Add your DIVX file
Drop one or more .divx files onto the converter above, or browse for them. They load into browser memory only — nothing is uploaded, so there is no size-based pricing and no server queue.
DIVX to WEBM
Converting .divx video to .webm means re-encoding the picture and sound into a different container and codec family, and this page does it entirely in your browser. Free, private, and validated — the file never leaves your browser.

Converting .divx video to .webm means re-encoding the picture and sound into a different container and codec family, and this page does it entirely in your browser. A .divx file is video packaged for the DivX ecosystem: an AVI-derived container carrying MPEG-4 Part 2 video compressed with the DivX codec. The extension appeared on rips and downloads throughout the 2000s, when DivX certification logos on DVD players promised these files would play from burned discs.
A .webm file is an open, royalty-free video container built specifically for the web. It restricts itself to free codecs, VP8, VP9, or AV1 for video with Vorbis or Opus for audio, so any browser can play a .webm without patent licensing concerns. For this route the practical draw is free of patent royalties end to end and vP9 and AV1 deliver excellent compression efficiency — balanced against older iPhones and legacy Safari versions cannot play it, which is worth knowing before you commit a large batch.
Why convert DIVX to WEBM?
The practical trigger for this conversion is usually a mismatch: with .divx, obsolete next to H.264 and H.265, needing more bits for the same quality. Switching to .webm buys you free of patent royalties end to end, which is why it is the better fit for serving HTML5 video without codec license fees. Because the conversion runs locally, trying it costs nothing but a few seconds of compute on your own machine.
DIVX vs WEBM at a glance
| Aspect | DivX video (.divx) | WebM video (.webm) |
|---|---|---|
| Format type | Container — quality depends on the codecs and settings inside | Container — quality depends on the codecs and settings inside |
| How it stores data | aVI-compatible RIFF layout extended by the DivX Media Format with menus, chapters, and XSUB bitmap subtitles | structured as a deliberately restricted subset of Matroska's EBML layout |
| Strongest at | playing movie archives from the 2000s downloading era | serving HTML5 video without codec license fees |
| Weak spot | obsolete next to H.264 and H.265, needing more bits for the same quality | older iPhones and legacy Safari versions cannot play it |
| Metadata | inherits RIFF INFO tags from AVI, plus DivX-specific chapter and menu structures in Media Format files | only a minimal set of Matroska tags such as title and language is defined for WebM; the spec deliberately omits attachments and rich tagging |
Pick WEBM as the output
Select .webm in the output menu next to each file. The menu only offers targets this engine can genuinely produce, so if WEBM is selectable, the route is real and validated.
Convert on your device
Press Convert. The conversion runs on an FFmpeg engine compiled to WebAssembly, executing entirely inside your browser tab.
Verify and download
Each result is signature-checked before the download unlocks, so a failed encode can never masquerade as a valid WEBM file. Outputs keep the original filename with the .webm extension.
DIVX to WEBM questions, answered
Will converting DIVX to WEBM lose quality?
Both sides are re-encoded, so expect a small generation loss controlled by the quality setting: divx is container-oriented and webm is container-oriented. For visually or audibly transparent results keep quality high; for smaller files lower it and compare.
Is it private to convert DIVX files here?
Yes — the .divx file is processed inside your browser tab and never uploaded. The conversion runs on an FFmpeg engine compiled to WebAssembly, executing entirely inside your browser tab. Close the tab and the file is gone from memory.
Where will the WEBM file work?
Chrome, Firefox, and Edge have played WebM for over a decade, and Safari added playback in 2021 starting with version 14.1 on macOS, with iOS following in iOS 15. Beyond browsers the picture thins out quickly, since many televisions, set-top boxes, and editors still expect MP4.
Will the WEBM file be bigger or smaller than my DIVX?
It depends on the content: structured as a deliberately restricted subset of Matroska's EBML layout. Convert one representative file first and compare before batch-processing a large set.
What happens to the metadata in my DIVX file?
This converter strips container metadata deliberately (the FFmpeg command runs with metadata mapping disabled) so exported files do not leak recording details. In the source, inherits RIFF INFO tags from AVI, plus DivX-specific chapter and menu structures in Media Format files; none of it is transmitted anywhere because the file never leaves your browser.
Can I convert WEBM back to DIVX?
Yes — the reverse route exists as a separate tool. Bear in mind that round-tripping .divx → .webm → .divx is not a perfect undo when any lossy step is involved; keep your original if fidelity matters.
