TTC to BZ2 Converter
Processing entirely on your device — large files may take a moment.
TTC packs several TrueType fonts into one file with shared glyph tables — how Microsoft and Apple ship CJK system fonts. The first member extracts as a normal TTF. Convert BZ2 to ZIP or TAR when modern tools need a friendlier container.
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 TTC format
TTC (TrueType Collection) is how you ship five CJK fonts in one download: a small ttcf header with member offsets points into shared glyph tables, so the fonts that differ only in metrics cost almost nothing extra. Microsoft's SimSun family and macOS system fonts are TTCs.
Most font tools want a single font, not a collection — extraction picks the first member and trims it to its own table directory, producing an ordinary TTF that every converter and @font-face rule accepts.
+Strengths
- ✓Shared glyphs make multi-font files small
- ✓Standard on Windows and macOS for CJK
- ✓First member extracts to a clean TTF
!Limitations
- −Most apps cannot use a collection directly
- −Web @font-face does not accept TTC
- −Members share glyphs — editing one is tricky
About the BZ2 format
BZ2 applies the Burrows–Wheeler transform: slower than gzip but noticeably smaller, which is why Wikipedia database dumps and old source tarballs still arrive as .bz2.
Few GUI tools ship a bz2 reader these days, so converting the contents into a ZIP or TAR is the practical way to hand the payload to someone else.
+Strengths
- ✓Better ratio than gzip
- ✓Common in dumps and archives
- ✓Mature, stable format
!Limitations
- −Slow to compress and decompress
- −Declining tool support
Why convert TTC to BZ2?
There is a concrete reason this conversion exists: Most apps cannot use a collection directly BZ2 sidesteps that — Better ratio than gzip If that is your situation, the tool above settles it in seconds, entirely on your device.
Frequently asked questions
Is this TTC to BZ2 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 TTC to BZ2?
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.
What about folders and directory structure?
The full directory tree is preserved: folders stay folders, and deep paths arrive exactly as they were packed in the TTC file.
Are the files inside my TTC archive modified?
No. Contents are unpacked in memory and repacked into BZ2 byte-for-byte — the conversion changes the container, never the files inside it.
