Courts, public tenders, patent offices and digital archives demand PDF/A — the ISO-standardized archival flavor of PDF that guarantees the file renders identically decades from now. Upload a regular PDF and get a PDF/A-2b back: fonts embedded, color profiles fixed, no external dependencies. One of very few free tools that does this at all.

PDF/A is an ISO standard (19005) for long-term archiving: every font is embedded, colors are device-independent, and features that break over time (JavaScript, external links, encryption) are forbidden. Courts, government tenders, registries and universities often reject regular PDFs and require PDF/A.
2b is the pragmatic sweet spot: unlike the older 1b it supports transparency and JPEG2000 (which modern PDFs contain anyway), and 'b' conformance (visual reproducibility) is what institutions actually check. It passes the common validators used by e-filing systems.
No — the page content is unchanged. The conversion embeds fonts, normalizes colors to device-independent RGB and adds the PDF/A metadata and output intent. Encrypted PDFs must be unlocked first (use Unlock PDF).
Yes — most competitors put PDF/A behind a paid desktop app. Here it's a free web tool: 20 operations a day, files auto-deleted from EU servers within 1 hour.
