About Smit Parekh & This Site
Working with me, response times, and how the free tools handle your data.
How much does it cost to hire a full-stack developer in India?
Rates for a senior full-stack developer in India typically range from $25–$60 per hour on the global freelance market, or ₹1.5L–₹4L per month for contract roles. Fixed-scope projects (MVP, redesign, feature build) are quoted per deliverable. Smit Parekh offers competitive rates for production-quality React, Next.js, and Node.js work — contact for a tailored estimate.
How long does it take to build a SaaS MVP?
A focused SaaS MVP — one core workflow, auth, and a basic dashboard — takes 4–8 weeks with a single senior developer. Timeline depends on scope: a FinTech transaction platform or multi-tenant system will be 8–16 weeks. Smit has shipped MVPs in as little as 3 weeks for well-scoped products using Next.js, Node.js, and PostgreSQL.
What is the difference between hiring a freelance developer and using a development agency?
A freelance developer is a single senior engineer who owns the full project — no account managers, no juniors, no handoff overhead. You get direct communication, faster iteration, and lower cost. An agency adds process, guarantees team continuity, and scales up for larger projects. For a 1–6 month product build, a senior freelancer like Smit Parekh typically delivers faster and cheaper with higher code quality than a comparable agency engagement.
What tech stack is best for building a production web application in 2025?
For most production web applications in 2025 the recommended stack is: Next.js (App Router) for the frontend and server-side rendering, Node.js with TypeScript for the backend API, PostgreSQL for the database, AWS or Vercel for deployment, and Docker for containerisation. This stack powers everything from indie SaaS to enterprise FinTech platforms and is the primary stack Smit Parekh uses across all client projects.
What should I look for when hiring a Next.js or React developer?
Look for: proven production deployments (not just side projects), TypeScript usage as a default, familiarity with server components and App Router in Next.js 14+, an understanding of performance (Core Web Vitals, Lighthouse), and experience integrating real backends (REST or GraphQL APIs, auth, databases). Ask to see past project code or GitHub. Smit Parekh has shipped 20+ production React and Next.js apps — view his portfolio for examples.
Do you work with international clients and which time zones?
Yes — clients across the US, UK, Canada, UAE, and Australia. Based in India (IST, UTC+5:30), which overlaps with EU mornings and US East Coast evenings. Async-first by default with daily updates; sync calls are scheduled to fit the client's working hours. No geographic barrier to collaboration.
What happens to files uploaded to the free tools?
Files are processed in memory and deleted immediately after the result is returned. Nothing is stored on the server. No account required, no data retained — privacy is a core design principle of every tool on this site.
Image Tools
Image Tools Questions
Edit, convert, and optimise images right in your browser - no upload required for most tools.
An AI-powered tool that automatically detects and removes the background from any photo. It outputs a transparent PNG in seconds - ideal for product images, profile photos, logos, and graphic design projects.
What types of images work best?
The tool works best on photos with clear separation between the subject and background - portraits, product shots, animals, and objects on plain backgrounds. Busy, cluttered backgrounds may require manual touch-up in an editor.
What image formats are supported?
You can upload JPEG, PNG, and WebP images. The result is always delivered as a transparent PNG.
Are there limits on how many images I can process?
No hard limits - you can process as many images as you need. Each image is processed and immediately discarded from the server.
Is my image stored on a server?
Images are sent to the AI model for processing and immediately deleted afterwards. We do not store, share, or use your images for any purpose.
What if the result has rough edges?
For best edge quality, use high-resolution images with good lighting and strong contrast between subject and background. You can further refine edges in any image editor like Photoshop or GIMP.
Is the background remover free?
Yes - completely free, no sign-up, no watermarks added to your output.
The tool reduces file size by re-encoding your image at the specified quality level. Higher quality = larger file, lower quality = smaller file. A setting of 75–85% typically cuts file size by 50–70% with minimal visible quality loss.
What is the best quality setting?
For web images, 75–80% provides an excellent balance between quality and file size. For print or archival purposes, use 90% or higher. For social media thumbnails, 65–70% is usually fine.
What image formats are supported?
JPEG, PNG, and WebP are supported. Note that compressing a PNG with JPEG output removes transparency - use PNG output to preserve it.
Is my image stored on a server after compression?
Images are temporarily processed on the server and immediately deleted after you download the result. No permanent storage.
Will the compression add a watermark?
No. Compressed images are returned clean - no watermarks, no branding, no modifications beyond the compression itself.
Is the image compressor free?
Yes - completely free with no usage limits, no account required.
You can convert between JPEG, PNG, and WebP. JPEG is best for photos, PNG for images with transparency, and WebP offers superior compression for web use with excellent quality.
Will my image lose quality during conversion?
Converting between lossy formats (e.g., PNG to JPEG) reduces some quality. You control the quality slider - higher values preserve more visual fidelity but produce larger files. WebP at 85% is usually indistinguishable from the original.
Which format is best for websites?
WebP is the best choice for web images in 2025. It provides 25–35% smaller file sizes than JPEG at equivalent quality. All modern browsers support it. Use PNG only when you need transparency.
Is my data secure? Are images stored?
No images are stored or uploaded. The entire conversion happens in your browser using the Canvas API. Your images never leave your device.
Is the image converter free to use?
Yes - completely free, no account, no upload limit. Since conversion happens in your browser, there are no server costs and the tool will always be free.
Can I convert multiple images at once?
Currently, the tool converts one image at a time. Upload a new image after downloading the previous conversion.
Content & SEO Tools
Content & SEO Tools Questions
Write better posts, audit your pages, and ship content that ranks and converts.
An AI-powered tool that writes high-engagement LinkedIn posts based on your topic, preferred tone (Professional, Casual, Inspirational, Story, Educational), and target audience. It handles structure, hook, and formatting so you can focus on publishing.
Will the generated posts actually get engagement?
The AI is trained on high-performing LinkedIn content patterns - strong hooks, concise paragraphs, calls to action, and appropriate length. While no tool guarantees virality, the output follows formats consistently shown to outperform generic posts.
Can I edit the generated post before publishing?
Yes - and you should. The generated post is a strong starting point. Personalise it with your own experience, data points, or anecdotes before posting. Authentic personal detail is what makes LinkedIn content resonate.
What is the LinkedIn character limit?
LinkedIn allows up to 3,000 characters per post. The generator stays within this limit by default. Posts that are 800–1,500 characters (about 150–280 words) tend to perform best.
Is this tool free to use?
Yes - completely free, no account required, unlimited generations.
What tones can I choose from?
You can choose from Professional, Casual, Inspirational, Story, and Educational. Each tone produces a distinctly different structure and voice - experiment to find what resonates with your audience.
Is it legal to download LinkedIn videos and images?
Downloading content for personal reference is generally accepted, but redistributing, re-uploading, or using others' content commercially without permission may violate LinkedIn's Terms of Service and copyright law. Always respect content ownership.
Why can't I download some LinkedIn videos?
This tool only works with public LinkedIn posts that anyone can view without logging in. Private posts, posts from private profiles, or content behind a login wall cannot be downloaded.
What format are downloaded videos saved in?
LinkedIn videos are typically saved in MP4 format, which is compatible with virtually all video players, phones, and editing software.
Are downloaded files stored on your server?
No. The tool fetches the media URL from LinkedIn and delivers it directly to you. No copies are saved on our servers.
How do I get the correct LinkedIn post URL?
On LinkedIn, click the three-dot menu (⋯) on the post and select 'Copy link to post'. Paste that URL into the tool. The URL should look like linkedin.com/posts/… or linkedin.com/feed/update/…
Is the LinkedIn Media Downloader free?
Yes - completely free, no account, no sign-up required.
What are meta tags and why do they matter for SEO?
Meta tags are HTML elements that tell search engines and social platforms what your page is about. The title and meta description directly affect your click-through rate from search results. Open Graph tags control how your content looks when shared on LinkedIn, Facebook, and WhatsApp. Missing or poorly written meta tags are one of the most common on-page SEO mistakes.
What meta tags does the checker analyse?
Title, meta description, canonical URL, Open Graph tags (og:title, og:description, og:image, og:url), Twitter Card tags, robots directives, and viewport tag - all the elements that affect search visibility and social sharing.
What is the ideal length for title and description tags?
Title tags: 50–60 characters. Meta descriptions: 150–160 characters. Going over these limits doesn't cause penalties, but Google will truncate the display in search results, which can reduce click-through rates.
What are Open Graph tags?
Open Graph tags (og:*) control how your content appears when shared on social media. Without them, platforms pick random text and images from your page - usually resulting in poor-looking shares with low engagement.
How often should I check my meta tags?
Check after any significant content update, when launching new pages, and quarterly as part of routine SEO maintenance. For pages where you notice dropping click-through rates in Google Search Console, check immediately.
Is the meta tag checker free?
Yes - completely free, no account required, unlimited URL checks.
The tool audits key on-page SEO factors including title tags, meta descriptions, heading structure (H1–H3), image alt text, canonical tags, internal and external links, page load signals, mobile-friendliness indicators, and structured data - all in one report.
How accurate is the SEO score?
The score reflects best practices aligned with Google's 2025 ranking guidelines. It is a solid indicator of your page's SEO health, but should be used alongside Google Search Console data for a complete picture of real-world performance.
How often should I run an SEO audit?
Run an audit after any significant content changes, when you notice ranking drops, when launching new pages, and at least monthly for important landing pages. Regular auditing catches regressions early.
Will fixing these issues improve my Google rankings?
Yes - implementing the recommendations addresses specific signals Google uses to evaluate pages. Users typically see measurable improvements within 4–12 weeks, depending on the competitiveness of their keywords and how many issues were fixed.
Is the SEO Analyzer free?
Yes - 100% free, no account required, no usage limits.
Can I get the report sent to my email?
Yes. Enter your email address in the optional field before running the analysis and a copy of the report will be sent to you.
The word counter analyses your text in real time as you type or paste it. It splits the text into words using standard word-boundary rules and counts each token instantly, with no server needed.
How is reading time calculated?
Reading time is estimated at 238 words per minute - the average adult silent reading speed per research. The estimate always rounds up to the nearest minute.
What is keyword density and why does it matter for SEO?
Keyword density is the percentage of times a specific word appears relative to the total word count. For SEO, a density of 1–3% for your primary keyword is considered natural. Higher than 3% may look like keyword stuffing to search engines and hurt rankings.
Is my text stored or shared?
No. All analysis happens entirely in your browser. Your text is never sent to any server, stored, or shared. It is 100% private.
Can I use this tool to check Twitter, LinkedIn, or Instagram limits?
Yes. The character count is shown in real time. Twitter allows 280 characters, LinkedIn posts up to 3,000, and Instagram captions up to 2,200.
Is there a character limit?
The tool handles standard document lengths without issue. For very large documents, performance depends on your device - most modern computers handle up to 100,000 characters smoothly.
Is the word counter free?
Yes - 100% free, no sign-up, no usage limits, works entirely in your browser.

Career & Dev Tools Questions
Practical utilities for developers and job seekers - secure passwords, QR codes, and ATS resume scoring.
You can encode website URLs, plain text, email addresses, phone numbers, SMS messages, and any other text-based content. Just enter the information and generate instantly.
What format will my QR code be downloaded in?
QR codes are downloaded as high-resolution PNG images, suitable for both digital and print materials.
Will my QR codes expire?
No. QR codes generated by this tool are static and will not expire. However, if the content they link to (e.g., a URL) becomes unavailable, the QR code will no longer lead to the intended destination.
Do I need an account to generate QR codes?
No account, no sign-up, no registration required. Generate as many QR codes as you need for free.
Can I use the QR codes commercially?
Yes. You are free to use the generated QR codes for personal and commercial purposes without restriction.
How do I test if my QR code works?
After generating, scan it with your smartphone camera or any QR code app. Most modern smartphones have built-in QR scanning in the native camera app - just point and tap.
Is the QR code generator free?
Yes - completely free, unlimited use, no account required.
An ATS (Applicant Tracking System) score measures how well your resume is structured and keyword-matched for automated parsing. Most companies use ATS software to filter resumes before a human ever reads them. A higher score means your resume is more likely to pass the initial filter.
What file formats are supported?
You can upload PDF or DOCX files. These are the two formats most commonly accepted by ATS systems - using any other format is itself an ATS red flag.
Is my resume data stored or shared?
No. Your resume text is sent to the AI model for analysis and immediately discarded. We do not store, share, or use your resume data for any other purpose.
Do I need to provide a job description?
No - the tool analyses your resume against general ATS best practices without a job description. However, tailoring your resume to a specific job description is the most effective way to improve your score for that role.
How do I improve a low ATS score?
The most common fixes are: use a clean, single-column layout; include keywords from the job posting; use standard headings (Experience, Education, Skills); avoid tables, graphics, and headers/footers; and save as PDF from Word (not Google Docs PDF).
Is the ATS resume checker free?
Yes - completely free, no account, no sign-up, unlimited analyses.
Yes. The tool uses the Web Crypto API (crypto.getRandomValues), a cryptographically secure random number generator built into every modern browser. It produces passwords that are statistically unpredictable and cannot be reproduced.
Are my passwords stored or sent to a server?
No. Every password is generated entirely in your browser using JavaScript. Nothing is ever sent to a server, stored, or logged. Your passwords are 100% private.
How long should my password be?
Security experts recommend at least 16 characters for important accounts. Longer passwords are exponentially harder to crack. For critical accounts like banking or email, use 20+ characters with all character types enabled.
Should I include symbols in my password?
Yes, whenever the website allows it. A 12-character password with symbols is roughly 1,000× harder to crack than one with only letters and numbers at the same length.
What makes a password 'Strong' in the strength meter?
The strength meter rates a password as Strong when it is at least 16 characters long and includes all four character types: uppercase letters, lowercase letters, numbers, and symbols. Each additional factor increments the score from Weak → Fair → Good → Strong.
How do I use strong passwords safely?
Use a password manager (like Bitwarden, 1Password, or KeePass) to store and auto-fill your generated passwords. Never reuse the same password across multiple sites.
Is this password generator free?
Yes - completely free, no account required, no usage limits. The generator runs entirely in your browser so no data is ever sent anywhere.
