Xvid to WEBM Converter
Processing entirely on your device — large files may take a moment.
Xvid Video and WebM Video exist for different jobs: Xvid is the open-source DivX competitor — the other MPEG-4 ASP encoder behind a decade of movie downloads. WebM delivers the best size-to-quality ratio for embedding video on websites without plugins.
Because the whole conversion happens on your device, it is instant, unlimited and genuinely private — no accounts, no watermarks, no files on anyone's server. Multiple files are converted in one go.

About the Xvid format
Xvid is the open-source implementation of the same MPEG-4 ASP profile DivX commercialized — after the original was open-sourced following a legal scuffle, Xvid became the encoder of choice for a decade of scene releases and personal rips.
Identical migration path as DivX: decode through ffmpeg, re-encode to H.264. The video quality at its usual bitrates survives the trip better than DivX's worst files, thanks to Xvid's tunable quantization.
+ Strengths
- ✓Open-source and configurable
- ✓Enormous existing content corpus
- ✓Decodes via ffmpeg everywhere
! Limitations
- −Same ASP-era limitations as DivX
- −Packed bitstream quirks in some files
- −Development ended years ago
About the WEBM format
WebM is Google's royalty-free video format for the web: a Matroska subset carrying VP8/VP9/AV1 video with Vorbis/Opus audio. YouTube serves most non-premium playback in VP9 WebM, and HTML5 `<video>` plays it natively in every modern browser — no licensing math required.
Efficiency is the selling point: VP9 and AV1 match or beat H.264/HEVC at the same quality for typical web content. Hardware decode is now widespread, though older Safari versions and some TVs remain the compatibility floor.
+ Strengths
- ✓Royalty-free codecs (VP9/AV1, Opus)
- ✓Native HTML5 video support
- ✓Efficient at web bitrates
! Limitations
- −Weaker support on older Safari/TVs
- −Not the default for camera or editor workflows
Why convert Xvid to WEBM?
There is a concrete reason this conversion exists: Same ASP-era limitations as DivX WEBM sidesteps that — Royalty-free codecs (VP9/AV1, Opus) If that is your situation, the tool above settles it in seconds, entirely on your device.
Frequently asked questions
Is this Xvid to WEBM converter really free?
Yes — completely free, with no sign-up, no watermark and no daily conversion limits. The site is supported by advertising.
Are my files uploaded to a server?
No. The conversion runs entirely inside your browser using WebAssembly, so your files never leave your device — that is what makes it instant and private.
Does it work on Windows, Mac, iPhone and Android?
Yes. Anything with a modern browser works: Windows, macOS, Linux, Android and iOS. No software installation is required.
Is there a file size limit for Xvid to WEBM?
The only limit is your device's memory, since nothing is uploaded. Files up to a few hundred megabytes work fine on a modern desktop browser; very large files simply take a little longer.
Does converting Xvid to WEBM re-encode my video?
Yes. The video is decoded and re-encoded with the settings chosen by the quality slider, which is what allows the format and size to change. For an archival copy, keep higher quality; for sharing, lower quality gives a much smaller file.
Will the audio track be kept?
Yes. The audio is carried over and re-encoded to the standard audio codec of WEBM, staying in sync with the video. If your Xvid file has multiple audio tracks, the first one is used.
