When You Actually Need to Convert PDF to PDF/A

PDF/A is required by courts and archives but unnecessary for most use cases. Here's how to tell which situation you're in.

PDF/A is mandatory for certain document submissions but unnecessary noise for everyday use. Here's how to tell the difference.

You need PDF/A when

  • A submission system explicitly requires it. Court e-filing portals, university thesis submission systems, government regulatory filings, patent applications often demand PDF/A.
  • You're archiving for long-term preservation. Documents you need to be openable in 20, 50, or 100 years should be PDF/A.
  • Internal compliance policy mandates it. Some industries (legal, financial, healthcare) require PDF/A for records that must be retained for regulatory periods.

You don't need PDF/A when

  • Sharing a document with a colleague this week. Regular PDF is fine.
  • Emailing a contract to a client. Regular PDF.
  • Posting a resume to a job portal. Regular PDF (unless the portal specifies otherwise).
  • General everyday document sharing. Regular PDF.

PDF/A isn't "better" — it's stricter. Stripping out features (encryption, JavaScript, multimedia) that you might actually want for normal documents.

How to convert

SwitchPDF PDF to PDF/A runs Ghostscript's PDF/A pipeline. Upload your regular PDF, click Convert, download. Takes about 10 seconds for typical documents.

The conversion:

  • Embeds all fonts (some get larger but ensure forward compatibility)
  • Removes encryption (PDF/A forbids it)
  • Strips JavaScript and embedded multimedia
  • Normalizes color profiles to ICC-defined standards
  • Rebuilds the document structure to comply with PDF/A-2b (the most widely accepted profile)

Verifying compliance

After conversion, validate with veraPDF (free, open-source). Some archival systems run their own validation on upload and reject non-compliant files with cryptic errors. Local validation first saves a round-trip.

Download veraPDF from verapdf.org, drag the converted file in, click Validate. You want to see "Compliant" with no validation errors.

What PDF/A doesn't change

  • Visual appearance is identical to the original
  • Text content unchanged
  • Page count, page sizes preserved
  • Hyperlinks survive
  • Form fields survive (without scripts)

The only visible differences are slightly larger file sizes (from embedded fonts) and missing interactive elements (any JavaScript-driven behavior is gone).

Common rejection reasons

If your PDF/A gets rejected by a submission system:

  • Fonts not embedded — happens with very custom or symbol fonts; replace them in the source if possible
  • Wrong profile — system expects PDF/A-1b (older, stricter) but you submitted PDF/A-2b
  • Transparency in PDF/A-1b — older profile doesn't allow it; either re-export without transparency or submit PDF/A-2b if accepted

Bottom line

Convert to PDF/A only when a system requires it. Validate with veraPDF before submitting. For everyday work, regular PDF is the right format.
