About PDF → PDF/A

Produce a genuinely PDF/A-1b (ISO 19005-1) compliant, long-term-archival copy of a PDF.

To guarantee real ISO 19005-1 compliance from any input PDF, this converter rasterizes every page at the chosen DPI onto a white background, embeds each page as a JPEG, and attaches the two PDF/A credentials validators look for — an sRGB output intent profile and the PDF/A-1b XMP conformance block. Because pages are flattened to images, selectable text is intentionally not preserved; use a high DPI (200+) for archive-fidelity legibility.

Where it is used

Submitting to archives, courts, or government agencies that mandate ISO 19005; future-proof document retention.

How to use the PDF → PDF/A

  1. PDF File — select a file (.pdf) — Up to 50 MB. File never leaves your browser..
  2. Document Title (optional) — enter the value (e.g. Archival title).
  3. Raster Quality (DPI) — enter the value in dpi (Higher = sharper text but larger file.).
  4. Calculate — press the Calculate button to see the result instantly above.

Formula

ISO 19005-1 (PDF/A-1b): rasterize each page against a white background, embed as JPEG, attach sRGB profile OutputIntent and PDF/A-1b XMP conformance metadata.

Frequently Asked Questions

Why is the text not copyable anymore?
PDF/A-1b compliance is guaranteed by rasterizing pages. This is the client-side way to pass strict PDF/A validators on any input file; the text is preserved visually at the DPI you choose.
