AVI (Audio Video Interleave) has been around since 1992 and is still found in screen recorders, security cameras, and legacy archives. While reliable, AVI files are often large and not supported by modern web platforms. Converting AVI to GIF lets you extract the best moments and share them as lightweight animations.
Upload your AVI file, trim it to the segment you want, choose your quality preset, and click Convert. Our FFmpeg-powered server handles all common AVI codecs — DivX, Xvid, MJPEG, and more — so you don't need to worry about compatibility.
AVI files can be very large because many use minimal compression. The trim tool is your best friend here — select only the seconds you need to keep the resulting GIF at a reasonable size. You can also reduce the output width to further shrink the file.
AVI (Audio Video Interleave) is a multimedia container format introduced by Microsoft in 1992. It can hold video and audio streams encoded with a wide variety of codecs. While largely superseded by MP4 and MKV for modern use, AVI remains common in older archives and certain recording software.
AVI has no MIME type in the HTML5 media stack and no browser compatibility row: it is not a web container. This matters because of how the editor works. Before anything is uploaded, your file is loaded into an HTML5 video element so you can scrub the timeline, set trim points, crop, and paint a mosaic mask. That preview uses your browser's decoder. Our server converts AVI without any issue — we verified a DivX-encoded AVI through the live upload path — but most browsers will not render an AVI for preview regardless of what is inside it. If the editor reports a load error, the file is not corrupt and the converter has not rejected it. Remuxing to MP4 is the reliable fix, and because it copies the existing streams into a new container rather than re-encoding them, it takes seconds rather than minutes.
Most AVI files in circulation carry DivX or Xvid, both MPEG-4 Part 2 variants from the early 2000s. Two things follow from that. First, MPEG-4 Part 2 is explicitly not playable in any current browser, so these are exactly the files that will fail at the preview step while converting perfectly well on the server. Second, these codecs are far less efficient than H.264, which is why an AVI can be several times larger than an MP4 of the same footage at similar visual quality. That inefficiency does not hurt the GIF you get — the GIF is re-encoded from decoded frames either way — but it does mean a long upload for a short result, so trimming before you upload saves real time.
A meaningful share of older AVI files are interlaced, because they came from DV camcorders, TV capture cards, or security systems that recorded in fields rather than full frames. Interlaced source shows up in a GIF as horizontal comb-like lines along moving edges, most visible on fast motion. GIF has no concept of fields, so the interlacing is baked into the frames you export. If you see that combing, deinterlace the file before uploading — most desktop tools have a deinterlace filter — because it cannot be corrected after conversion. Static or slow-moving footage rarely shows the artefact, so this only matters for clips with real movement.
Server-side, FFmpeg decodes DivX, Xvid, MJPEG, H.264 and uncompressed video. The narrower constraint is your browser, which has to decode the file for the preview and trim step before upload — and AVI is not a container browsers support. That is why an AVI can convert correctly on the server yet still fail to open in the editor.
Almost certainly not. Browsers do not support AVI as a container, and the DivX or Xvid codec inside most AVI files is not playable in any current browser either. The editor needs a preview to let you trim and crop, so it stops there. Remux to MP4 first — it copies the streams without re-encoding and takes seconds.
The upload limit is 500 MB. For larger files, we recommend trimming the AVI on your computer first, or using a shorter clip.
Yes. GIF is an image format and does not support audio. Only the visual frames are converted.
Most clips finish in 10 to 30 seconds, and processing is capped at two minutes. Upload is usually the slowest part rather than conversion, and AVI is affected more than most formats because DivX and Xvid are inefficient compared with H.264 — the same footage is simply a bigger file to send.
That is interlacing, and it is common in AVI files from DV camcorders, TV capture cards, and security systems that recorded fields rather than full frames. GIF has no concept of fields, so the comb pattern is baked into the exported frames. Deinterlace the file in a desktop tool before uploading; it cannot be fixed afterwards.
Absolutely. The conversion happens on our server, so it works on any device with a web browser — iPhone, Android, tablet, or desktop.
