orConvert PDFs to PDF/A — the ISO standard for long-term document archiving used by governments, libraries and enterprises. If an institution ever asked you for an “archival PDF”, this is what they meant.
PDF/A compliance isn't just a file extension — every font must be embedded, colors mapped to standard profiles, and encryption removed, then the result validated against the ISO standard. That validation pipeline runs on a server. We're building it.
PDF/A is an ISO-standardized flavor of PDF designed to stay readable for decades — fonts embedded, no encryption, no external dependencies. Governments, courts, libraries and enterprises require it for archiving.
Both guarantee visual preservation (“b” = basic). The number is the generation — 2b is the common modern choice; 3b additionally allows embedding arbitrary files like spreadsheets.
No — the extension doesn't make it compliant. Real PDF/A needs font embedding, color profile mapping and validation, which is what the upcoming converter does.
It should look identical — PDF/A restricts features (like encryption), but visually the pages stay the same.
