Frequently asked questions

Everything worth knowing before you convert a file.

help

What is PDF/A, exactly?

An ISO-standardized (ISO 19005) version of PDF built for long-term archiving — every font is embedded and a color profile is included, so the file doesn't depend on anything outside itself to render correctly, today or decades from now.

help

Will this change how my file looks?

No. PDF/A doesn't alter your document's visible content or layout — it only embeds fonts, a color profile, and metadata that make the file self-contained.

help

What if my file can't be converted?

Password-protected PDFs aren't supported — PDF/A doesn't allow encryption at all, so you'll need to remove the password first. A small number of unusual files may also fail; you'll see a clear error rather than a file that only looks right.

help

Is my file kept after converting it?

No. Your file is processed only to create the PDF/A version, then deleted from our servers right away. Max file size: 1 GB.
