PDF to PDF/A — frequently asked questions

What is PDF/A and why use it?
PDF/A is an ISO-standardized version of PDF for archiving. It embeds fonts and resources so the document will display identically far into the future, which is why archives and courts often require it.
How is PDF/A different from a normal PDF?
PDF/A forbids features that depend on external resources or that could change rendering over time, such as unembedded fonts and certain encryption, making it self-contained and stable.
Will the appearance change after conversion?
No. The document looks the same; the conversion mainly embeds resources and removes elements that are not allowed in the archival standard.
Is my file kept private?
Yes. Files are transferred over encrypted HTTPS and automatically deleted from our servers after conversion.
