A quick guide to the three formats
JPG is the everyday photo format: small files, works everywhere, no transparency. PNG is lossless and supports transparency, but files are larger. WebP is newer and usually smaller than both, and supports transparency too.

Frequently asked questions
Are my files uploaded anywhere?
No. Everything happens inside your browser, on your own device. Your files are never sent to a server, and you can confirm that in your browser's network tab. Close the tab and they're gone.
Which format should I choose?
JPG for photos that need to work everywhere and stay small. PNG for graphics, screenshots and anything with transparency. WebP for the smallest files on websites.
What happens to transparency?
PNG and WebP keep transparent areas. JPG cannot, so transparent areas turn white when you save as JPG.
Which input formats work?
JPG, PNG, WebP, GIF, BMP and AVIF work in most modern browsers. HEIC photos from an iPhone open too, in every browser. Animated images are converted using their first frame.
Can I process several images at once?
Yes. Add as many as you like (up to 50). Each one is processed on its own, and you download them together as a ZIP.
Is there a file size limit?
Each file can be up to 100 MB, and up to 300 MB in total. Because the work happens on your device, very large files depend on your available memory. A desktop browser handles them best.
