How to Convert AVIF to GIF
- Drag your AVIF into the drop zone above, or click to browse and select it.
- Choose GIF from the Output Format menu. There is no quality slider — GIF has no quality setting, only its 256-color palette.
- Download the GIF, or drop several AVIF files at once and take them away as a ZIP.
Your browser decodes the AVIF, so the conversion works anywhere AVIF itself opens — Chrome and Edge since version 85, Firefox since 93, and Safari since 16. If the AVIF displays when you open it in a new tab, this tool can convert it. Nothing is uploaded: the file never leaves your machine.
Converting an Animated AVIF to an Animated GIF
The honest answer up front: this tool cannot do it. It draws the AVIF onto a canvas, which yields the first frame and nothing else, and writes that single frame out as a static GIF. Rebuilding an animation means decoding every frame, choosing a palette per frame, and re-encoding the timing and disposal rules — real work for a real encoder, not a canvas.
If you have ffmpeg installed, one command does it properly. The two-pass palette filters are what separate a decent animated GIF from a muddy one:palettegen studies the whole clip and builds the best 256 colors for it, then paletteuse maps every frame onto them.
ffmpeg -i input.avif \
-vf "fps=15,scale=480:-1:flags=lanczos,split[a][b];[a]palettegen[p];[b][p]paletteuse" \
output.giffps=15andscale=480are the two dials that matter for file size. An animated GIF has no compression between frames, so every frame you keep and every pixel you widen costs bytes in full.flags=lanczospicks a sharper resampler than the default, which is worth having when you are already giving up so much color.- The GIF loops forever without you asking. Add
-loop -1before the output filename if you want it to play through exactly once. - Reading animated AVIF needs an ffmpeg built with an AV1 decoder such as libdav1d. Recent builds have one; very old ones do not.
Before you run it, though, be sure GIF is really the target. An animated AVIF is a short AV1 video in an image container, with inter-frame compression and full color. Flattening it to GIF throws away both, and the result is commonly many times the size of the original at markedly worse quality. GIF earns that cost in exactly one situation: somewhere that plays an image inline and automatically, with no click, and will not accept a video. If your destination accepts modern formats, animated WebP or MP4 keeps the motion without the penalty — the reasoning is laid out in GIF to MP4.
When to Convert AVIF to GIF
GIF is the most universally readable raster format there is, and that is its entire remaining advantage. Convert when you hit one of these:
- Software or apps that can't open AVIF but accept GIF
- Older email clients where AVIF simply won't display
- Platforms, forums, or forms that specifically require a GIF upload
- Sharing simple graphics, logos, or icons for maximum reach
- Embedding an image somewhere AVIF support is unreliable
Worth checking first: many places that cannot read AVIF can read PNG and JPG perfectly well, and both handle a modern image far better than GIF does. If the requirement is "a format this thing understands" rather than "a GIF specifically", use AVIF to PNG for graphics and transparency, or AVIF to JPG for photographs. Reach for GIF when something is genuinely asking for a .gif.
What the Conversion Costs You
Color. GIF caps each frame at 256 colors, while AVIF stores millions and can carry 10- or 12-bit HDR. Reducing to a palette is the whole of the conversion, and it is irreversible. Photographs, skies, and smooth gradients suffer most; flat illustrations, line art, and screenshots barely notice.
Transparency.AVIF's alpha channel has 256 levels of translucency. GIF has one palette entry meaning "draw nothing here". Every pixel that is less than half opaque becomes fully transparent, everything else becomes fully opaque, and a soft feathered edge or drop shadow turns into a jagged one. An image with transparency also drops to 255 usable colors, since one entry is spent on the transparent index.
File size. Counter-intuitively, the GIF is usually largerthan the AVIF despite holding far less information. GIF compresses with LZW over palette indices and has no way to predict a pixel from its neighbours; AVIF uses AV1's intra-frame compression. Dithering widens the gap further, because the fine speckle it introduces is noise, and noise does not compress. Keep the original AVIF for archiving and use the GIF only where it is actually needed.
AVIF vs GIF
| AVIF | GIF | |
|---|---|---|
| Colors | Millions, up to 12-bit HDR | 256 per frame |
| Transparency | Full alpha channel | One on/off index |
| Animation | Yes, AV1 inter-frame compression | Yes, no compression between frames |
| Compression | AV1 intra-frame, lossy or lossless | LZW over palette indices |
| Introduced | 2019 | 1987 |
| Support | Chrome 85+, Firefox 93+, Safari 16+ | Universal |
AVIF wins every technical row and loses the only one that forces a conversion. Both formats can hold animation, but they were built for different eras: animated AVIF inherits the AV1 video codec and delivers full-color motion at a fraction of a GIF's size, while animated GIF stores each frame as its own 256-color image and grows accordingly. GIF endures because it plays inline and automatically in places that will not embed a video. If you want small, high-quality animation for the modern web, the target is AVIF or WebP — see AVIF to WebP, which is broadly supported and still far more efficient than GIF. To pick a format by where the image is going rather than by habit, the image format by use case guide walks through each one.
What This Converter Actually Does
Three steps, and knowing them explains every surprise on this page. First the browser decodes the AVIF with its own built-in decoder and draws it onto a canvas. A canvas holds one frame of 8-bit sRGB pixels, which is why an animated AVIF arrives as its first frame and why HDR is flattened before anything else happens.
Then those pixels are reduced to a palette. The encoder bins every color into a 15-bit histogram and runs median cut over it: start with all the colors in one box, repeatedly split the box with the most to gain along its widest channel, and stop at 256 entries — or 255, when the image has transparency and one entry must be reserved. Pixels less than half opaque are assigned to that transparent index.
Finally the image is dithered and compressed. Floyd–Steinberg error diffusion spreads each pixel's rounding error into its neighbours, trading visible banding for a fine speckle that the eye blends at normal viewing distance. The resulting index stream is LZW-compressed and wrapped in a GIF89a container. All of it runs as JavaScript on your machine — no file is uploaded. Going the other way, GIF to WebP keeps an animated GIF animated.
Frequently Asked Questions
Why convert AVIF to GIF?
Compatibility, and essentially nothing else. AVIF is a modern format that older software, some email clients, and a few upload forms still can't open, while GIF has been readable by everything for over thirty years. Converting gives you a file that works in legacy tools and in the places that specifically demand a GIF. It does not give you a smaller or better-looking image — the GIF will usually be both larger and worse than the AVIF you started with.
Can this convert an animated AVIF to an animated GIF?
No. This converter renders the first frame of the AVIF and produces a single-frame, static GIF. Rebuilding the motion means decoding every frame and re-encoding it with a per-frame palette and timing, which is a job for a dedicated encoder rather than a browser canvas. If you need the animation, the ffmpeg command on this page does it in one pass. For most AVIF files — which are single still images — the static GIF you get here is exactly what you wanted.
Will AVIF to GIF conversion lose quality?
Yes, and often visibly. GIF stores at most 256 colors per frame while AVIF stores millions and can carry 10- or 12-bit HDR, so the palette has to be thrown away. Photographs, skies, and smooth gradients show banding; dithering hides some of it by trading it for a fine speckle. Flat illustrations, logos, line art, and screenshots with a handful of colors convert with little visible difference.
What happens to AVIF transparency in a GIF?
It becomes a hard on/off mask. AVIF has a full alpha channel with 256 levels of translucency; GIF has a single palette entry meaning "draw nothing here". This converter treats any pixel less than half opaque as fully transparent and every other pixel as fully opaque. Soft, feathered edges and drop shadows therefore come out with jagged, aliased borders. When the image has transparency the palette drops to 255 colors, because one entry is spent on the transparent index.
Why does my converted GIF look speckled or grainy?
That is dithering, and it is deliberate. Rather than snapping each pixel to the nearest of 256 palette colors — which turns a gradient into visible stripes — the encoder uses Floyd–Steinberg error diffusion, pushing each pixel's rounding error into its neighbours. Up close this reads as fine noise; at normal viewing size it reads as a smoother gradient than banding would. It is the standard trade in every serious GIF encoder.
Why is my GIF bigger than the AVIF?
Because GIF's compression is from 1987. It uses LZW over a stream of palette indices, with no concept of predicting one pixel from its neighbours, while AVIF uses the AV1 video codec's intra-frame compression. For a photograph, the GIF is routinely several times the size of the AVIF despite holding far less color information. Dithering makes this worse, because the speckle it adds is noise and noise does not compress. This is normal, and it is why GIF is worth reaching for only when something downstream requires it.
Is GIF a good replacement for AVIF?
Only for compatibility. AVIF produces far smaller files with far better quality, so keep AVIF wherever it is supported. Use GIF only when a platform or piece of software cannot read AVIF, or when a GIF is specifically required. If the target simply needs a widely supported format rather than GIF in particular, PNG is the better choice for graphics and JPG for photographs — both compress modern images far better than GIF does.
Is there a size limit on the GIF?
The format caps each side at 65,535 pixels, and the converter will tell you if an image exceeds that. In practice you will never meet this limit; you will meet a slow browser and an enormous file long before it. There is no limit on how many files you convert, and no watermark or sign-up.
Are my files uploaded to a server?
No. Your browser decodes the AVIF and the GIF is assembled byte by byte in memory on your own machine — the palette, the dithering, and the LZW compression all run as JavaScript on your device. Nothing is transmitted anywhere, which matters when the image is a client's artwork or an unreleased design. Drop several AVIF files at once and take them away together as a ZIP.
