PFB to XZ Converter
Processing entirely on your device — large files may take a moment.
PostScript Font (Binary) and XZ Compressed File exist for different jobs: PFB is Type 1 PostScript in binary segments — length-prefixed blocks instead of printable hex, the form X11 and printer drivers actually want on disk. Unpack XZ into ZIP/TAR for tools that cannot read LZMA2.
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 PFB format
PFB packages the same Type 1 font as length-prefixed binary segments — ASCII header, encrypted binary body, ASCII trailer — marked with 0x80 sentinel bytes. This is the on-disk form X11 font servers, printer drivers and Ghostscript expect, and it is about 30% smaller than the ASCII PFA.
Converting PFB to PFA turns every segment back into printable text — handy for diffing fonts, patching hinting by hand or feeding interpreters that only accept ASCII.
+Strengths
- ✓Compact binary form of Type 1
- ✓The form X11/drivers actually install
- ✓Lossless round-trip with PFA
!Limitations
- −Not human-readable
- −Type 1 is end-of-life at Adobe
- −Segment size cap of 64KB per block
About the XZ format
XZ wraps the LZMA2 algorithm: the best ratio of the common Unix compressors, which is why distribution packages and source releases pick it when bandwidth matters more than CPU.
Windows Explorer and many cross-platform tools cannot open it — unpacking to ZIP or TAR makes the payload portable.
+Strengths
- ✓Highest common ratio
- ✓Standard for Linux packages
- ✓Integrity checks built in
!Limitations
- −Memory-hungry at high settings
- −Sparse support outside Linux
Why convert PFB to XZ?
There is a concrete reason this conversion exists: Not human-readable XZ sidesteps that — Highest common ratio If that is your situation, the tool above settles it in seconds, entirely on your device.
Frequently asked questions
Is this PFB to XZ 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 PFB to XZ?
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 PFB file.
Are the files inside my PFB archive modified?
No. Contents are unpacked in memory and repacked into XZ byte-for-byte — the conversion changes the container, never the files inside it.
