What is a DivX file?
DivX stands for DivX video. It was created by DivX, Inc. and first released in 2001. 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.
| Type | video |
|---|---|
| Compression | Lossy |
| Usually contains | MPEG-4 Part 2 (DivX) video with MP3 or AC3 audio |
| In a browser | does not play in browsers; plays in VLC and DivX-certified players |
| Common uses | films shared in the 2000s and DivX-certified DVD players |
| MIME type | video/divx |
Which format should you convert DivX to?
- DivX to MP4 to play on any phone, computer or TV, or to upload to YouTube and social media.
DivX is already lossy, so converting it to a lossless format makes the file bigger without improving it; pick a lossless target only if a program requires one.
How to open a DivX file
Whether a DivX file opens with a double click depends on the device. Here is what works on each, without buying software:
| Windows | Films and TV and Media Player open the common formats; VLC opens almost any video file, DivX included. |
|---|---|
| Mac | QuickTime Player opens formats Apple supports; VLC or IINA open the rest. |
| iPhone and iPad | The Files app plays formats Apple supports. For others, a player such as VLC for iOS, or converting the file here, is the easiest route. |
| Android | Most gallery and music apps play the common formats; VLC for Android plays almost everything. |
| Web browser | DivX does not play in browsers; plays in VLC and DivX-certified players. |

| MOV | Lossy | H.264, HEVC or ProRes video with AAC audio | 1991 | iPhone recordings, Final Cut Pro and screen recordings on Mac |
| MKV | Lossy | almost any codec, often H.264 or H.265 with several audio and subtitle tracks | 2002 | films and TV rips, OBS recordings and anime releases |

Tips for converting DivX files without losing quality
DivX is lossy, so some detail was already discarded when the file was made. Converting it cannot bring that back. Converting to a lossless format preserves what is left exactly but makes the file larger; converting to another lossy format adds a small extra loss, which is invisible at sensible settings.
- Keep the original recording. Every re-encode costs a little detail, so convert from the best copy you have, not from a file that was already converted.
- Know whether you need a new container or a new codec. MOV, MKV and MP4 can all hold H.264 video, and switching between them is fast and lossless; changing the codec means re-encoding, which is slower.
- For sharing, MP4 with H.264 at 1080p or 720p is the safe choice: every phone, browser and social network plays it.
- Phones record at very high bitrates. If a file is too big to send, lowering the resolution to 720p usually shrinks it far more than any quality setting.
Convert DivX files from the command line
Everything this page does can also be done in a terminal. The most common DivX conversion, to AVI, looks like this with ffmpeg:
ffmpeg -i input.divx -c:v mpeg4 -q:v 4 -vtag xvid -c:a libmp3lame -b:a 192k output.aviChange the output extension to pick another format. The converter above runs the same ffmpeg engine inside your browser, so you get the result without installing anything.
