M4R to TBZ2 Converter
Processing entirely on your device — large files may take a moment.
Convert TBZ2 exactly like TAR.BZ2. If your files are still in M4R format, this page is the shortcut: M4R is Apple’s ringtone format — technically an AAC file capped at 40 seconds that iTunes and iPhones recognise as a ringtone.
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 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
About the TBZ2 format
TAR.BZ2 pairs the tar container with bzip2 compression — the classic release artifact of the 2000s Unix world. Bzip2's block-sorting algorithm compresses text and source trees noticeably tighter than gzip, which is why distribution mirrors and source releases favoured it for years.
Today it has largely ceded the top spot to TAR.XZ (smaller) and tar.gz (faster), but countless build scripts, mirrors and legacy toolchains still expect the exact .tar.bz2 artifact — and producing it is a matter of running the tar through a bzip2 encoder.
+Strengths
- ✓Tighter than gzip on text and source trees
- ✓Classic, universally supported on Unix-like systems
- ✓Deterministic, well-understood artifact for releases
!Limitations
- −Slow compression compared to gzip/zstd
- −Larger than TAR.XZ for the same content
- −Single stream — no random file access
Why convert M4R to TBZ2?
Think of it as moving your file to the container that fits the job. Hard 40-second length cap TBZ2 works differently: Tighter than gzip on text and source trees If any of that sounds like your task, run the conversion — it takes seconds and nothing leaves your device.
Frequently asked questions
Is this M4R to TBZ2 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 M4R to TBZ2?
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.
Are tags like title and artist preserved?
Tag handling varies between target formats and this conversion focuses on the audio itself. For archival copies where tags matter, keep the original file; the converted copy is for playback and sharing.
Can I convert a whole folder of M4R files?
You can select many files at once and they are processed in a single batch. Output files land in one ZIP download when there is more than one result.
