PDF/A to XZ Converter
Processing entirely on your device — large files may take a moment.
PDF/A Archive and XZ Compressed File exist for different jobs: PDF/A is the ISO-standardized archival dialect of PDF: everything needed to render the document — fonts, color profiles, no external dependencies — must be embedded, and encryption or dynamic content is forbidden. The point is that the file renders identically in decades. 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 PDF/A format
PDF/A is what happens when archives get to rewrite the rules. Regular PDF allows external fonts, unembedded color profiles, JavaScript, video and encryption — conveniences that quietly rot: open the file on another machine in twenty years and the layout may not survive. PDF/A (ISO 19005) bans everything that needs an outside dependency or a runtime: fonts must be embedded, color must be tagged with an OutputIntent, encryption and executable content are forbidden. The result is a PDF that is a complete, self-contained time capsule.
There are conformance levels (b = basic, a = accessible) and generations (PDF/A-1, -2, -3). PDF/A-2b is the pragmatic sweet spot: it allows modern compression and transparency while keeping validation strict, and it is the level most universities, courts and tender portals actually ask for. Conversion runs Ghostscript's pdfwrite through a PDF/A OutputIntent with an embedded sRGB profile, then validates that nothing violates the profile.
+Strengths
- ✓Self-contained: fonts and colors embedded, renders identically forever
- ✓Accepted by archives, courts, universities and tender portals
- ✓ISO-standardized — not a vendor-specific dialect
!Limitations
- −Forms, JavaScript and encryption are stripped
- −File size usually grows (embedded fonts + profiles)
- −Visually identical output — you get compliance, not a new look
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 PDF/A to XZ?
There is a concrete reason this conversion exists: Forms, JavaScript and encryption are stripped 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 PDF/A 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 PDF/A 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.
Is there a size limit for archive conversion?
There is no upload cap because nothing is uploaded — the practical limit is your device memory. A few hundred megabytes of unpacked content works comfortably on a modern computer.
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 PDF/A file.
