PDF to PDF/A Converter - Best Effort
Upload a PDF to get a best-effort PDF/A-style approximation: a standard sRGB color profile and PDF/A conformance metadata embedded, plus a check of whether the document's fonts are already embedded.
Perguntas frequentes
Is the output a real, certified PDF/A file?
No, and this tool doesn't claim it is. True PDF/A (ISO 19005) conformance is verified against the full spec with a dedicated validator such as veraPDF, which this free browser tool doesn't have access to. What it does is a genuine best-effort approximation of the parts of PDF/A that matter most for basic archival use: an embedded sRGB color profile (as the document's OutputIntent) and an XMP metadata packet declaring PDF/A-1B conformance intent.
What about embedding fonts?
PDF/A requires all fonts to be embedded. This tool checks and reports which fonts (if any) in your source PDF aren't embedded, but it can't embed a font after the fact - that requires the original font program, which pdf-lib doesn't have access to for a font that was never embedded. If fonts are missing, re-export the original document with font embedding turned on, then convert again.
Should I use this for legal or regulatory archiving?
Only after verifying the output with a dedicated PDF/A validator. This tool is meant for casual/basic archival purposes where an approximation is good enough - not as a substitute for real compliance validation where it's legally required.
Is my PDF uploaded to a server?
No, the whole conversion happens entirely in your browser using pdf-lib. Nothing is sent anywhere.
