Frequently Asked Questions

What is PDF/A and why would I need it?

PDF/A is an ISO-standardized archival format that ensures documents remain viewable long-term. Government agencies, courts, and archives often require PDF/A submissions.

What changes does the conversion make?

The tool embeds all fonts, converts color spaces to sRGB, removes JavaScript and multimedia, and adds the required PDF/A metadata.

Will the document look different after conversion?

Visually the document should look the same. Transparency may be flattened in PDF/A-1b, and embedded multimedia will be removed since PDF/A does not allow it.
