DivX to FLAC Converter
Processing entirely on your device — large files may take a moment.
DivX Video and FLAC Lossless Audio exist for different jobs: DivX is the MPEG-4 ASP profile that defined movie sharing and DVD-player compatibility in the 2000s — most "AVI movies" of the era are DivX. Convert to FLAC when you want a permanent, lossless archive of your music.
This converter runs entirely in your browser using WebAssembly — your files never leave your device, nothing is uploaded, and there are no watermarks, sign-ups or queues. Drop in several files at once to convert them as a batch.

About the DivX format
DivX was the codec that made movie-sharing possible on a CD-R: MPEG-4 ASP at a bitrate that fit a 90-minute film into 700MB. The .divx container is DivX's own variant of AVI with chapter and menu extensions, and a decade of downloaded movies carry it.
Conversion to MP4 is straightforward — the MPEG-4 ASP video decodes through ffmpeg and re-encodes to H.264 at half the size for phones and smart TVs that never learned the DivX profile.
+ Strengths
- ✓Enormous installed base of content
- ✓Hardware players supported it for a decade
- ✓Decodes cleanly via ffmpeg
! Limitations
- −QPEL/GMC profiles break some decoders
- −MPEG-4 ASP artifacts at low bitrates
- −Superseded by H.264 everywhere
About the FLAC format
FLAC (Free Lossless Audio Codec, Xiph, 2001) compresses audio to roughly 50–60% of its PCM size and restores every bit on playback — a ZIP for music that also carries proper tags, hi-res support up to 32-bit/655 kHz on paper (24-bit/192 kHz in practice) and full open-source pedigree. It is the archive format of digital music collections.
Support followed maturity: every serious player, modern Android (system-level), most cars and streaming purists' devices handle FLAC natively. Apple resisted for years but iOS 11+ plays it, with the caveat that iTunes/Apple Music syncing still prefers ALAC. The price of losslessness is size — about five times MP3 at comparable quality.
+ Strengths
- ✓Bit-perfect lossless with real compression
- ✓Hi-res capable (24-bit/192 kHz)
- ✓Open, unpatented, tag-native
! Limitations
- −~5× the size of lossy formats
- −Apple syncing prefers ALAC
- −Overkill for casual listening

Frequently asked questions
Is this DivX to FLAC 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 DivX to FLAC?
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.
Will the audio track be kept?
Yes. The audio is carried over and re-encoded to the standard audio codec of FLAC, staying in sync with the video. If your DivX file has multiple audio tracks, the first one is used.
Does converting DivX to FLAC 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.
