Xvid to M4R Converter
Processing entirely on your device — large files may take a moment.
Xvid is the open-source DivX competitor — the other MPEG-4 ASP encoder behind a decade of movie downloads. Converting MP3 to M4R is how you turn any song into a proper iPhone ringtone that syncs via Finder or iTunes.
iLoveConverter processes everything locally on your computer, which makes it private and fast: no upload wait, no server storage, no limits. Add as many files as you like — batch conversion is built in.

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 M4R format
M4R is simply iPhone ringtone packaging: an AAC audio file (same as M4A) capped at 40 seconds, named .m4r so iOS treats it as a ringtone instead of a song. GarageBand and Finder sync are the supported paths to install one; the audio itself is ordinary AAC.
Practical workflow: pick the 30–40 second chorus you want, convert to M4R, sync it to the phone, and set it in Sounds & Haptics. Nothing about the audio changes — the extension and the length limit are the entire format.
+ Strengths
- ✓The native iPhone ringtone format
- ✓Simple — it is AAC with a new name
! Limitations
- −Hard 40-second length cap
- −Installation requires sync or GarageBand

Think of it as moving your file to the container that fits the job. Same ASP-era limitations as DivX M4R works differently: The native iPhone ringtone format If any of that sounds like your task, run the conversion — it takes seconds and nothing leaves your device.
Frequently asked questions
Is this Xvid to M4R 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 M4R?
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 M4R 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.
Why is video conversion slower than image conversion?
Every frame has to be decoded and re-encoded. This site runs that work on your own CPU via WebAssembly — nothing is uploaded, but a multi-minute video reasonably takes a few minutes. Images, by comparison, are single-frame jobs.
