What is PDF/A and why do I need it?▾
PDF/A is an ISO-standardised archival format designed for long-term preservation. It embeds fonts and colour profiles so the document renders identically decades from now. Courts, governments, and archives often require it.
What version of PDF/A does fwip produce?▾
fwip converts to PDF/A-2b, the most widely accepted conformance level. It requires visual appearance preservation and embedded colour profiles.
Does the conversion change my PDF content?▾
The visible content stays identical. fwip adds an sRGB colour profile, XMP metadata, and MarkInfo, then strips JavaScript and actions that PDF/A prohibits.
How do I verify my PDF is valid PDF/A?▾
fwip produces PDF/A-compatible output. You can verify the result with fwip's <a href="/tools/validate-pdfa/">Validate PDF/A</a> tool, or use a certified validator like veraPDF.
Can I convert PDF/A without Adobe Acrobat?▾
Yes — fwip converts to PDF/A entirely in your browser. No Acrobat, no subscription, no software to install.
