About this PDF to PDF/A converter

PDF/A is an ISO standard designed for reliable long-term preservation. Our converter embeds all fonts, ensures device-independent color profiles, and removes features that can break in the future (like JavaScript or audio/video).

When should I use PDF/A?

  • Regulatory filings and legal documents.
  • Academic papers, theses, and long-term records.
  • Any PDF that must look the same years from now.

Best practices before converting to PDF/A

  • Make sure your fonts are allowed to be embedded. Missing fonts can be substituted.
  • For scanned PDFs, run OCR first (use JPG → Text (OCR)) to keep text searchable.
  • Optimize file size with Compress PDF if the document contains many images.
