Which PDF/A levels do you support?

PDF/A-1b, PDF/A-2b, and PDF/A-3b. Pick PDF/A-2b for most modern archival needs; PDF/A-1b for the strictest legacy compliance.

What's the difference between PDF and PDF/A?

PDF/A is a subset designed for long-term archival. It embeds all fonts, color profiles, and metadata required to render the document identically decades from now — no external dependencies.

Will conversion change how the document looks?

Visually no. The conversion adds embedded fonts and color profiles where missing and removes anything PDF/A forbids (encryption, JavaScript, embedded video). The page content stays the same.

My PDF to PDF/A job is stuck on "processing".

Refresh the page and try again. Browser-side processing depends on your device's CPU and RAM, so closing other tabs usually helps.

The downloaded file looks different from the preview.

Clear your browser cache and re-run the job. Outdated cached fonts can occasionally cause rendering glitches. If the issue persists, email us a sample to help@pdfwix.com.

Can I undo a PDF to PDF/A operation?

Your original file is never modified — PDFWix always produces a new file. Just discard the new version and start again with the original.
