Convert a GIF image to a still AVIF file. Encoded in your browser, free, no upload.

    Drop GIF files here or choose files.

    • Up to 30MB per file, 10 images at a time, 40 megapixels max
    • AVIF encoding is slow. A 10 megapixel photo takes about 10 to 30 seconds, longer on a phone
    • Animated GIF: only the first frame is saved (no animated AVIF)

    Normal is hard to tell from the original. Use High for images with a lot of text, Light when file size matters most.

    How it works

    Pick your GIF files, choose a quality and click Convert. Several files are converted one after another, and you can save them one by one or as a ZIP. The result card compares the original and AVIF sizes.

    Transparent backgrounds are kept. Only the first frame of an animated GIF is saved, so if you need the motion, use GIF to MP4 or WebM.

    Things to know

    Every current browser opens AVIF, but older Windows Photos and some forum and store admin pages still do not. Check that the destination accepts AVIF, and keep the original if you are not sure.

    Encoding happens on your device, so bigger photos take longer. Resize photos over 40 megapixels before converting.

    Frequently asked questions

    Does an animated GIF become an animated AVIF?

    No. This tool saves only the first frame as AVIF and says so in the result card. To keep the motion and still cut the size, GIF to MP4 or WebM is a better fit.

    The AVIF file will not open.

    Current Chrome, Edge, Firefox, Safari (iOS 16 and later) and the current Windows Photos app open AVIF. Older Windows Photos and Paint, some forum and store admin pages, and older image editors may not open it or may refuse the upload. For those, JPG or WebP is the safe choice.

    Why does it take so long?

    AVIF compresses very well, but encoding takes a lot of computation. This tool does not send photos to a server. It encodes on your device, so one photo can take anywhere from a few seconds to over a minute depending on the hardware. For many or large photos a desktop computer is faster, and a phone may stop if the screen turns off.

    Do my photos get uploaded to a server?

    No. The first run downloads the AVIF encoder module (about 3.5MB), and after that decoding and encoding happen inside this browser. Results disappear when you close the page, so use the save button to download them.
