Supported formats

Input: JPG, PNG, WebP, AVIF, HEIC, GIF, BMP, SVG, ICO
Output: JPG, PNG, WebP, AVIF

Which format should I choose?

JPG: photos, maximum compatibility. PNG: graphics, screenshots, transparency, lossless editing. WebP: websites – smaller than JPG and PNG, supports transparency. AVIF: the smallest files for websites, supported by all current browsers but not by older software.

Quality and codecs

Images are encoded with MozJPEG, libwebp and libavif – the same high-quality encoders used by Google’s Squoosh – compiled to WebAssembly and run on your device.

Limitations

Animated GIF/WebP are converted as a single frame.
TIFF and RAW camera files are not supported by browsers.

Privacy

Files you choose are read into your browser’s memory and processed on your device; they are not uploaded to a server. Temporary download links are released after use, and the offline cache never stores your documents. More about privacy and limits.
