avif
AV1 Image File Format
The current efficiency leader, often half the size of JPEG at matching quality. Encoding is slow.
Free, no account, no watermark. Converted on our servers, then deleted.
Drop an AVIF file here
As many as you like. We will show you what they convert to.
Drop an AVIF file onto the converter, or pick one from your device. You can add several at once.
Pick GIF as the output format. Open Settings if you want to control the quality, how long to spend, and whether to keep EXIF, and 2 more.
Convert and download the finished file. No account, and nothing to install.

Graphics Interchange Format
Limited to 256 colours, but still the lowest common denominator for short looping animation.
Yes. AVIF keeps everything, and GIF does not: it throws away detail to make the file smaller, and converting back cannot bring it back. If you need every detail kept, convert to PNG instead.
Yes, and the file will open — but a round trip is not free. Each pass re-encodes, so going AVIF to GIF and back leaves you with less than you started with.
You can set the quality, how long to spend, whether to keep EXIF, the width and height, and whether to enlarge. Anything left on Auto is decided by the encoder, which is usually the right answer unless you are targeting a specific size or device.
On our server. The file is sent over HTTPS and converted in a sandbox with no network access of its own; your input and the result go together, removed at once if it fails and otherwise kept for a few minutes so you can download them, then deleted — whether or not you did. There are no accounts for anything to be kept against.
Yes — there is a per-file cap and an hourly job limit, because this runs on one small server. The API page states the limits currently in force rather than a number baked into this page.
