GIF – Graphics Interchange Format

GIF dates from 1987 and is best known for short looping animations. Each frame is limited to 256 colours and transparency is on or off only, so photographs often look banded. It is still handy for simple graphics and animations that need to work everywhere.

AVIF – AV1 Image File Format

AVIF is a modern image format built on the AV1 video codec. It supports transparency and high dynamic range, and it often produces the smallest files of any web image format at a given quality. Encoding is slower than for JPG or WebP, and older browsers and some apps cannot open it.

Frequently asked questions

How do I convert GIF to AVIF?

Click Select File or drop your GIF file onto the upload box. Pick the quality and maximum size, and the converted AVIF appears in the list below with a download button. You can add many files at once and download them together as a ZIP.

Is it really free?

Yes. There is no sign-up and no watermark. To keep the service available for everyone there is a 95MB limit per file and a cap on how many files one connection can process in a short period.

Are my files stored?

Your upload is used only to make the converted file. Images are processed in memory; other files are written to a private temporary folder that is deleted as soon as the conversion finishes. Nothing is kept after the result has been sent back.

Will quality drop?

For images, a little, by design: the image is re-encoded at the Quality you choose (default 75%). Audio and video are re-encoded with high-quality settings; documents keep their text and layout as far as the target format allows. Converting never restores detail that is already missing from the original.

How this works: your file is uploaded over HTTPS and converted on this server with open-source engines (libvips for images, FFmpeg for audio and video, LibreOffice and Pandoc for documents, Calibre for ebooks, Ghostscript and Inkscape for PDF and vector files). Images are processed in memory; other files use a private temporary folder that is deleted as soon as the conversion finishes.
