Asked
Questions
Quick answers about this PurePDF workflow.
Is PDF to PDF/A conversion free?
Yes. Converting to archival PDF/A format is free with no signup.
What is PDF/A and why use it?
PDF/A is the ISO-standardized archival version of PDF. It embeds fonts and prohibits external dependencies so documents render identically decades from now. Courts, governments, and archives often require it.
Do my files get uploaded to a server?
No. The conversion runs in your browser — your document never leaves your device.
Which PDF/A version does the tool produce?
The tool targets PDF/A-2b, the most widely accepted level for visual archiving.
Will my document look different after conversion?
No. PDF/A preserves the exact visual appearance; it adds embedded fonts and metadata for long-term stability.
How can I verify the result is PDF/A compliant?
Open the file in Adobe Acrobat — compliant files show a blue PDF/A banner. Dedicated validators like veraPDF also confirm compliance.
