AVI and DivX videos from the 2000s use MPEG-4 (DivX/Xvid) codecs that today's browsers and phones can't decode. This page converts AVI to H.264 MP4 on your device and plays it. No codec packs, no hunting for an old player.
How to use it
- 1Click 'Choose AVI files' or drop files onto the page. A whole folder works too.
- 2Click a file in the grid to start preparation — the container is first remuxed to MP4 (a few seconds), and if the browser can't decode that codec it is converted automatically with a progress indicator.
- 3Once ready it plays in place. ← → for the next file, F for full screen, Esc back to the grid.
How it works
The container is remuxed to MP4 first. If the video inside is DivX/Xvid (MPEG-4 Part 2) the browser can't draw it and the picture stays black — the viewer detects that and moves straight on to H.264 conversion, shown with a progress indicator. MP3 or AC3 audio becomes AAC.
Preparation runs on ffmpeg.wasm inside the browser. The engine (about 30 MB) is downloaded once on first use and cached after that. Prepared results are held in memory briefly and vanish when the tab closes. Files over 900 MB don't fit in browser memory — convert them first with the Video Converter tool.
Limits
Very old codecs such as DivX 3 (MS-MPEG4 v3), Indeo, and Cinepak aren't supported and won't play. Conversion can be slower than real time, so long videos take a while (3–10 minutes for a 10-minute video depending on the PC). Files over 900 MB aren't opened.
Good for
Checking AVI from old camcorders and digital cameras, sorting out an old downloads folder, and previewing family videos before backing them up.
Frequently asked questions
Why do some AVIs play instantly and others take long?+
It's the codec inside. AVI holding H.264 only needs a remux (seconds); DivX/Xvid needs conversion, which takes time proportional to length.
I hear audio but see no picture.+
That's a remuxed copy the browser can't draw; the viewer detects it and converts automatically. Wait for the progress indicator. If it never appears, the codec is one of the unsupported old ones.
Can I save the converted MP4?+
This page only makes a temporary playback copy. To keep a file, convert to MP4 in the Video Converter tool and download it.
