Frequently Asked Questions
What is PDF/A?
PDF/A is an ISO-standardised version of PDF designed for long-term archiving. It embeds all fonts and colour information and forbids features (like external links or JavaScript) that could make the file render differently in the future.
Is my PDF uploaded to a server?
No. Conversion runs entirely in your browser using a WebAssembly build of Ghostscript. Your document never leaves your device.
Which conformance level should I choose?
PDF/A-2b is a good default for most archiving. PDF/A-1b is the oldest and strictest (often required by courts and government). PDF/A-3b additionally allows embedded source files.
Will fonts and images be preserved?
Yes. Fonts are embedded and colours are converted to an sRGB output intent so the document looks the same on any compliant viewer.
Are password-protected PDFs supported?
No. Remove the password first (for example with the PDF Password tool), then convert the unlocked PDF to PDF/A.
Is it free?
Yes — completely free, no account, no watermark, and no conversion limit.
