PDF/A is an ISO-standardized PDF variant designed for archival. It removes dependencies (fonts, links, JavaScript) so the file displays identically decades later, when current PDF software no longer exists.
PDF/A-1b is widely supported and minimal. PDF/A-2b adds compression and transparency support (recommended for most archival needs). PDF/A-3 allows embedding source files (e.g., invoice XML alongside PDF rendering).
No. Visual appearance is identical. The conversion embeds fonts and removes external dependencies behind the scenes — the page content displays the same.
Archives must remain accessible — encrypted files become unreadable if passwords are lost. PDF/A removes encryption to guarantee future readability.
JavaScript is removed for PDF/A compliance. Form fields are preserved in PDF/A-2 and PDF/A-3 but become static (non-fillable) in PDF/A-1.
Yes. The PDF to PDF/A converter handles scanned PDFs — but for searchable archives, run OCR first (use our OCR tool) before converting to PDF/A.
Yes — 30 conversions per day for guests, more on free accounts. No watermark on output.
Slightly. Embedded fonts add 50-200 KB. PDF/A-2b compression often offsets this. Net size change is typically within ±10%.
