Supports: AVI
AVI (Audio Video Interleave) is a Microsoft container from 1992 — older than most file formats people use daily. It still hangs around in legacy archives: DivX/XviD downloads from the Kazaa/eMule era, MJPEG-encoded camcorder tapes, capture-card recordings of TV broadcasts, and the default output of older screen recorders like CamStudio. AVI plays in VLC and a handful of other players, but rarely renders inline anywhere. GIF embeds in every messaging app, every forum, every documentation page, and every email client made in the last 30 years. Common reasons to convert AVI to GIF:
| Property | AVI | GIF |
|---|---|---|
| Container | Microsoft RIFF (1992) | Image format (1987) |
| Typical codecs | DivX, XviD, MJPEG, Cinepak, uncompressed | Per-frame LZW |
| Color depth | 24-bit (16M colors) | 8-bit (256 colors max) |
| Audio | Yes (MP3, PCM, AC3) | No |
| Typical size for 5-sec clip | 5-50 MB (codec dependent) | 1-8 MB |
| Universal playback | VLC + a few apps | Every device, every viewer |
| Looping | Manual | Automatic |
| Best for | Legacy archives, capture cards | Embedding, sharing, reactions |
A 30 MB DivX AVI commonly drops to a 2-5 MB GIF at the right settings — a rare case where converting to a "less efficient" format actually shrinks the file because GIF doesn't carry audio or codec metadata, and the visual stream is downscaled. For audio-bearing clips that need universal playback, AVI to MP4 is the better path.
| Setting | Effect on size | Best for |
|---|---|---|
| 24-30 fps, 256 colors | Largest, smoothest | Film captures, animated cartoons in AVI |
| 15 fps, 128 colors | Balanced | Camcorder clips, DivX movie scenes |
| 10 fps, 64 colors | Compact | Reaction GIFs, GitHub READMEs |
| 8 fps, 32 colors | Smallest | Long clips that must fit a forum upload |
No, usually the opposite. AVI files are big mostly because of audio tracks and old codecs (DivX, MJPEG, uncompressed) plus full-resolution video. GIF strips audio entirely, downscales to whatever resolution you choose, and quantizes color to 256. A 700 MB, 90-minute AVI converted as a 5-second clip at 480 px wide, 12 fps, 64 colors will land at 1-3 MB. The size depends on your trim, resolution, fps, and palette — not the source file size.
The common ones: DivX, XviD, MJPEG, Cinepak, MPEG-4, Indeo, and uncompressed AVI from FireWire camcorder captures. If your AVI plays in VLC, it almost certainly converts here. AVI files using exotic 1990s codecs (early Indeo, Microsoft Video 1) may need a re-encode first — try AVI to MP4 to normalize the container before converting to GIF.
Yes. Use "specific frame" mode to grab one frame at a chosen timestamp, or "multiple frames" to extract a sequence as separate images. Output supports JPG and PNG if you don't need animation — see AVI to JPG and AVI to PNG for that.
No — GIF has no audio support. The original AVI's audio (MP3, PCM, AC3, etc.) is dropped during conversion. If you need to keep sound, convert to AVI to MP4 or AVI to WebM instead.
Drop fps to 10, set width to 480 px, palette to 64 colors. A 5-second clip at those settings typically lands at 1-3 MB. For tighter caps or longer clips, trim the AVI first using AVI cutter and reduce duration to 2-3 seconds. Old DivX movies tend to compress especially well at 64 colors because the source already has limited color range.
10-15 fps. Most DivX/XviD encodes from the early 2000s were already 23.976 or 25 fps, and dropping to 12-15 fps preserves perceived motion while halving file size. For very fast action (sports, fight scenes), 20 fps avoids stutter. Avoid 30+ fps unless the source is genuinely smooth high-frame-rate content — it doubles output size for marginal gain.
Yes — drop in as many AVI files as you want. Each converts in parallel within your browser session. Settings can apply to all files or be tuned per-file. Download individually or as a ZIP. Useful for archiving a folder of old camcorder clips into a shareable GIF set.
GIF caps at 256 colors per frame. Old DivX rips with film grain or gradients (sky, fog, dark scenes) show banding and dithering artifacts in GIF that aren't visible in the AVI source. Bump palette to 256 colors and quality to High to minimize this. For grain-heavy footage, AVI to WebM preserves full color and produces a smaller file than GIF — at the cost of GIF's universal embedding.
