What happens when you convert AVI to DivX
- If the video inside the AVI is already MPEG-4 Part 2, the tool first copies the streams straight into the DivX. That takes seconds and loses nothing.
- If a copy is not possible, it re-encodes to MPEG-4 Part 2 video labelled DivX, with MP3 audio, in an AVI container, which is slow in a browser: expect several times the video's length for HD footage, less at lower resolutions.
- The video is labelled with the DIVX code that DivX Certified DVD players and TVs look for. Older DivX players only play up to 720 by 576, so choose 480p for them.
How to convert AVI to DivX online
- Press "Choose AVI files" and select one or more files, or drag them onto the box. You can add files of any size your device can hold in memory.
- Adjust the settings if you need to: resolution and quality control the size of the result. The defaults suit most people.
- Press "Convert to DivX". The first audio or video conversion downloads the converter engine, about 32 MB, which your browser then keeps for next time.
- Save each DivX with its download button. Close the tab and every trace of the files is gone from memory.
Why convert AVI to DivX?
AVI files usually come from older camcorders, digital cameras and legacy video libraries. People convert them to DivX because DivX is what DivX Certified DVD players, older smart TVs and car entertainment systems play from a disc or USB stick.
In short, AVI is good at what it was made for, and DivX is the more practical choice when the file has to play, upload or edit somewhere else. AVI does not play in browsers; plays in VLC and Windows players, while DivX does not play in browsers; plays in VLC and DivX-certified players.
How to convert AVI to DivX on Windows, Mac, iPhone and Android
On Windows
Open this page in Chrome, Edge or Firefox, drag your AVI files in from File Explorer, and press Convert. Each DivX is saved to your Downloads folder. If you prefer a desktop program, VLC can also convert AVI to DivX: choose Media, then Convert / Save.
On a Mac
Safari, Chrome and Firefox all work. Drag the AVI files from Finder onto the drop zone and the DivX files land in Downloads.
On iPhone and iPad
Open the page in Safari and tap Choose AVI files. You can pick from Photos or from the Files app. The converted DivX appears in Files, in the Downloads folder; to put it in your photo library, open it there, tap Share and choose Save Video.
On Android
Open the page in Chrome, tap Choose AVI files and pick them from Files or your gallery. The DivX is saved to the Download folder, where any file manager can find it. Keep the screen on while a long video converts, because Android may pause a tab in the background.
Best settings for AVI to DivX
DivX is written as MPEG-4 Part 2 video labelled DivX, with MP3 audio, in an AVI container. The Resolution setting is the one to reach for: 1080p keeps full HD detail, 720p is plenty for phones and laptops and roughly halves the size, and 480p suits email and old devices. Leave Resolution on Keep original and Quality on Standard, and an AVI whose video is already MPEG-4 Part 2 is copied into the DivX rather than re-encoded, which is fast and loses nothing.
The quality levels map to the H.264 CRF scale where the target uses H.264, and to fixed high-quality settings for older codecs such as MPEG-2, MPEG-4 Part 2, WMV and Theora. Re-encoding always costs a little detail, so convert from the best copy of the AVI you have.

About AVI and DivX files
What is an AVI file?
AVI dates from Windows 3.1 and predates the codecs most people use today. It is still readable by almost every desktop editor, which is why some older software asks for it.
What is a DivX file?
DivX squeezed a DVD film onto a single CD, which made it the file-sharing format of the early 2000s. The codec is MPEG-4 Part 2, a generation older than H.264.
AVI to DivX not working? Common problems
- The conversion is slow. Audio and container changes take seconds, but re-encoding video runs on your own processor. Lower the resolution to 720p, close other tabs, and keep the device plugged in.
- The tab stops or reloads on a very large file. Browsers limit how much memory one tab can use, around 2 GB and less on phones. Split long recordings or convert them on a computer.
- The DivX will not play on an old device. Try the other formats offered for AVI, or choose 720p, which older players handle more reliably.
Convert AVI to DivX with ffmpeg
This converter runs ffmpeg inside your browser. If you would rather use the ffmpeg command line on your own computer, this command produces an equivalent DivX with the same kind of settings:
ffmpeg -i input.avi -c:v mpeg4 -q:v 4 -vtag DIVX -c:a libmp3lame -b:a 192k -f avi output.divxReplace input.avi with the name of your file. For a whole folder of AVI files, run the command in a loop, or drop them all on the converter above, which processes them one after another.
AVI to DivX converter FAQ
Will I lose quality converting AVI to DivX?
A little. Both formats are lossy, so re-encoding compounds the loss slightly. Keep the default quality or higher and the difference is rarely noticeable.
Why is the DivX a different size from the AVI?
If the video inside the AVI is already MPEG-4 Part 2, it is copied and the DivX comes out about the same size. Otherwise, compared with video made with a modern codec such as H.264, the DivX is usually two to four times larger, because MPEG-4 Part 2 needs more data for the same picture. Choose 720p or 480p for a smaller file.
Are my AVI files uploaded anywhere?
No. The conversion runs inside this browser tab using ffmpeg compiled to WebAssembly, so your files stay on your device. You can disconnect from the internet after the page and converter engine have loaded and it still works.
Can I convert several AVI files to DivX at once?
Yes. Select or drop as many files as you like; they are converted one after another and each gets its own download button.
How do I open a DivX file?
DivX does not play in browsers; plays in VLC and DivX-certified players. DivX is common for films shared in the 2000s and DivX-certified DVD players.
Is this AVI to DivX converter free?
Yes. There is no sign-up, no watermark and no limit on how many files you convert. The site is paid for by advertising, and because conversions run on your device there is no server cost per file.
Can I convert AVI to DivX on my phone?
Yes. The converter works in Safari on iPhone and iPad and in Chrome on Android. Long HD videos convert more slowly on a phone than on a computer.
