FREQUENTLY ASKED QUESTIONS

Common Questions About PDF to PDF/A

This tool prepares the file toward PDF/A-1b — a clean rebuild plus archival metadata and the conformance stamp. For certified compliance (courts, government archives), validate the result with a dedicated validator such as veraPDF.
PDF/A is the ISO standard for documents meant to last decades: it demands self-contained files with archival metadata. This tool rebuilds your document toward that shape.
No — the pages, text and images are preserved as-is; only the structure and metadata are brought into archival shape.
Full PDF/A-1b forbids some constructs (certain fonts, encryption, external references) that a browser-side rebuild cannot always remove. That is exactly why the tool is honest about being preparation, not certification.
No — everything runs locally in your browser.
