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.
