What is Image Converter?

Convert images between JPEG, PNG, and WebP entirely in your browser using the Canvas API. Drop a file, pick the output format, and tune the quality slider to balance file size against visual fidelity. Files never leave your device - conversion is fully client-side, private, and works offline once the page is loaded. Useful for shrinking JPEGs to WebP before deploying to a website, swapping screenshot formats for upload requirements, or batch-preparing assets for an online store.

FAQ

Image Converter - Frequently Asked Questions

Everything you need to know before you start.

What image formats can I convert?

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.

More about Image Converter

Convert images locally - no upload, no privacy worries

Unlike most online converters that upload your file to a server, this tool uses your browser's Canvas API to convert images entirely on your device. That means your screenshots, designs, and personal photos never travel across the internet, and conversion still works even if your connection drops after the page loads. It is ideal for converting legacy JPEGs to WebP before a deploy, or swapping a PNG to JPEG to meet a platform's upload requirement.
