Convert GIF to AVIF
Drop GIF files and download them as AVIF. Both formats support transparency, which is preserved. Conversion runs on your device, so large batches finish in seconds and nothing is uploaded.
How to use the GIF to AVIF
- Drop or paste your GIF files (up to 200).
- Set the AVIF quality (90 is visually lossless).
- Click Convert to AVIF.
- Download each file or all as a ZIP.
Why convert GIF to AVIF?
GIF is limited to 256 colours per frame, which ruins photos but suits simple animations and flat graphics. It supports one-bit transparency (a pixel is either fully opaque or fully transparent).
AVIF is based on the AV1 video codec and typically beats WebP by another 20–30% at the same quality, with transparency and HDR support. Browser support is universal since 2024, but many image editors, email clients and upload forms do not accept it yet.
What changes in the conversion
GIF is lossless and AVIF is lossy: the conversion trades a little detail for a much smaller file. At quality 90 the difference is invisible for photos; for text and line art keep quality high or prefer a lossless target. Both formats support transparency, which is preserved. Animated GIF files are converted to a still image of the first frame.

How it works on your device
Your browser decodes the GIF file into raw pixels, draws them onto a canvas and asks its built-in encoder to write AVIF (Chrome and Edge; Firefox and Safari cannot yet write AVIF and the tool will say so). Nothing is sent to a server, which is why there is no file-size limit beyond your device's memory and no queue.
