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.
Typical use: Convert PDF to PDF/A when a thesis, invoice, tender or government filing must be archived in a compliance-friendly, self-contained form.
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.
