What PDF to PDF/A does
PDF to PDF/A performs a best-effort archival cleanup of a PDF — rebuilding its structure and setting clean metadata — but does not produce a certified ISO PDF/A file.
PDF/A is the archival flavour of PDF, designed so a document opens and looks identical decades from now. Real conformance is strict: every font used must be embedded, colour must be pinned down by a verified ICC profile, and encryption is forbidden entirely.
Two of those cannot be honestly guaranteed for an arbitrary uploaded file from inside a browser, so this tool does not claim the badge. What it genuinely does is worthwhile on its own: it re-serialises the document from scratch, which repairs a lot of malformed and inconsistent files, and writes clean explicit metadata. If you need a file that will actually pass a PDF/A validator, we would rather tell you to use a dedicated tool than sell you a sticker.

PDF to PDF/A: details and limits
This is not a certified PDF/A-1B converter and the output is not guaranteed to pass a compliance validator. If a court, government body or records system requires genuine PDF/A, use a dedicated desktop tool or a print-to-PDF/A driver.
What it does do reliably: rebuilds the file structure (which fixes many subtly broken PDFs), and sets clean creation and modification metadata.
PDF/A forbids encryption, so protected files are handled rather than waved through. A PDF that only carries permission restrictions is decrypted and written out clean. One that needs a password to open is turned away — unlock it first.
An existing creation date is kept; only a missing one is invented. Producer and Creator, though, are overwritten with BabaPDF, so the original producer string is lost — that is a real change to a file you may be archiving precisely for its provenance.
True conformance additionally needs a verified embedded ICC colour profile and a guarantee that every font in use is embedded — neither can be established for an arbitrary file in a browser.
Flatten PDF in "Everything to images" mode gets you closer to the practical goal of "looks the same forever", though it also loses selectable text.

What PDF/A actually requires
PDF/A demands embedded fonts and a colour profile a browser cannot reliably supply — so honest online tools do archival cleanup, not certified conversion.
