GIF to AVIF Details
When something needs AVIF instead of GIF, GIF to AVIF keeps every step on one screen: upload, queue, convert, download.
GIF keeps at most 256 colours per frame and can hold a short animation inside a single file. AVIF is the still-image half of the AV1 codec and holds detail well even at low bitrates.
How to use it
If this is your first visit, here is how it behaves.
- Add the GIF files you want converted by dragging them in or clicking to browse.
- Files line up in the queue as you add them. The ceiling is 20 files, so run a second round for more.
- Use the convert button on a single row, or the batch button to run the whole queue at once.
- Rename the output in the queue field before downloading; the extension is set to AVIF for you.
- Downloading is the last step: the AVIF file goes to your browser folder and no copy stays on the server.
Formats, limits and behaviour
The limits match what the interface shows, and the processing behaves like this:
- Accepted input: GIF (gif), up to 24 MB per file.
- The result is written as AVIF and encoded at quality 60, which is why the file shrinks so much.
- The queue carries 20 files at a time, and each file travels in its own request.
- Transparent pixels survive the trip because AVIF supports an alpha channel.
- Upload an animated GIF and the AVIF result comes from the first frame; the rest are dropped.
- GIF is lossless while AVIF is encoded with loss, so hard lines and small text can soften slightly at the edges.
- Do not count on metadata surviving: whether EXIF and ICC data travel depends on the engine handling the file, so keep anything critical elsewhere.
When to choose this tool
If you hold GIF files and the destination genuinely wants AVIF, this is the right page. Hero images, high-resolution photography and pages that pay attention to mobile data cost benefit most. It usually lands smaller than WebP at matching quality, but encoding is slower and old software support is thin. GIF keeps at most 256 colours per frame and can hold a short animation inside a single file.
AVIF gives you the smallest file when page speed is the priority. If the file has to open in older software, WebP or JPG output is the safer call.
Practical notes
- Filling the queue with 20 files and hitting convert all is faster than working through them one by one.
- Renaming outputs in the queue keeps your downloads folder readable once several AVIF files land there.
- AVIF is encoded with loss, so converting the same file repeatedly costs quality. Keep the original.
- Open the AVIF file afterwards and check edges and colour gradients, and keep the GIF source where it is.
Data and privacy
Processing an image means uploading it, and that upload lives only as long as the request. Once the output exists, the file is not stored and never handed to a third party. Ads may appear on the page, but no ad network can reach your upload.
