What is DivX?
DivX is a video codec and media format developed by DivX, LLC. It became widely popular in the early 2000s as one of the first formats capable of compressing DVD-quality video into files small enough to share over the internet.
DivX is based on the MPEG-4 Part 2 video standard and uses the .divx or .avi file extension. While largely superseded by H.264 and H.265, many older video libraries still contain DivX files.
How DivX Works
DivX is an implementation of the MPEG-4 Part 2 Advanced Simple Profile video codec, typically wrapped in an AVI container and paired with MP3 or AC-3 audio.[1] Its efficient compression let a two-hour film fit on a single CD-R at acceptable quality, a capability that drove its popularity for ripping and sharing DVDs.[2]
History
The name traces to a 1999 hack called "DivX ;-)" that repurposed Microsoft's MPEG-4 video codec; in 2000 Jerome Rota and Jordan Greenhall founded a company (later DivX, Inc., then DivX, LLC) to develop a clean, standards-based encoder.[3] The open-source project Xvid emerged in parallel as a free alternative implementing the same MPEG-4 Part 2 standard.[2]
DivX vs Modern Codecs
Because it is based on MPEG-4 Part 2, DivX is substantially less efficient than later standards such as H.264 (AVC) and H.265 (HEVC), which superseded it for streaming and high-definition video.[2] The Library of Congress documents DivX as a format of its era, now chiefly encountered in legacy video libraries.[1]

DivX is an MPEG-4 Part 2 codec from the DVD-rip era; H.264 and H.265 offer far better compression.
Pros & Cons of DivX
Advantages
Significantly smaller than uncompressed video while maintaining DVD-quality appearance.
Most older media players and DivX-certified DVD players support it natively.
Stable and well-understood with extensive software support.
Disadvantages
Superseded by H.264 and H.265 which offer better quality at smaller file sizes.
Modern browsers and mobile devices do not support DivX natively.
Requires licensed encoders and decoders.
When to Use DivX

Can modern players play DivX files?
Yes, VLC Media Player can play most DivX files. Modern browsers do not support DivX natively.
Is DivX still relevant today?
DivX is largely superseded by MP4 but many existing video archives use it. Converting DivX to MP4 is recommended.
How do I convert DivX to MP4?
Use our online converter, VLC, HandBrake, or FFmpeg. Most tools handle DivX conversion easily.
What is the difference between DivX and AVI?
AVI is a container format while DivX is a video codec. A DivX file is typically an AVI container with DivX video encoding inside.
Is DivX the same as Xvid?
No. DivX and Xvid are competing MPEG-4 Part 2 codecs. Xvid is the open-source equivalent of DivX.
