PDF/A to PDF

How to fix a PDF/A that opens read only

Upload the file above and download the copy. That is the whole fix, and it takes a couple of seconds.

The reason it is that simple is worth knowing. Nothing about your file is locked. No password was set, no permissions were changed, and the document is not damaged. Your reader spotted a small block of metadata saying “this is an archival copy” and decided to protect you from yourself by disabling edits.

We tell people this constantly, because the alternative theories are so much more alarming. Anyone who has spent twenty minutes hunting for a password that does not exist has met this behaviour. Clear the flag and the file behaves normally again.

How to convert PDF/A to normal PDF in your browser

Your document never leaves your device. The rewrite happens in this tab, which matters given what archival PDFs usually contain — contracts, deposited records, medical files, evidence bundles.

1. Choose the file. Drag it onto the panel or click to browse.
2. Read the result. We report which level the file declared, so you know what it was before you changed it. Note it down if you will need to convert back to the same level later.
3. Download and edit. The copy opens normally in any editor, including our own PDF editor.

If the panel tells you it found no identification to remove, that is useful information rather than a failure. It means archival mode was never the problem.

What removing PDF/A information actually changes

One block of XMP metadata, and nothing else. This is the same operation Acrobat performs under Preflight, and we kept it just as narrow on purpose.

Your embedded fonts stay embedded. The output intent and its colour profile stay put. Page content, bookmarks, annotations and attachments are untouched. The file still renders identically anywhere — it simply no longer claims to be archival.

That last distinction is the honest argument for doing it this way. A PDF/A file stops being a faithful archival copy the second you edit it. Leaving the declaration in place on a document you are about to change would make the file lie about itself, and a validator would eventually catch the mismatch. Removing the claim first is the tidier sequence. You can confirm the before and after with our PDF/A validator, which reads the same metadata block.

Should you turn off PDF/A mode in your reader instead?

Sometimes, yes. In Acrobat the setting lives under Preferences → Documents, where archival viewing can be set to never. Nothing about the file changes, which is the appealing part.

The catch is that it only helps on your machine. Email the document to a colleague and they meet exactly the same wall, then ask you what is wrong with the file. It also switches the behaviour off for every archival document you ever open, including the ones you genuinely did not intend to modify.

So the rule we use is simple. Change the preference for a one-off you are reading yourself. Change the file when it has to move between people. There is a longer walkthrough of both routes in editing a PDF/A file.

When to go from PDF/A to PDF, and when not to

Good reasons: the file is yours, you need to correct it, and archival mode is in the way. A supervisor sent back a thesis chapter. A contract needs a clause amended before signature. A scanned bundle needs pages reordered.

Bad reasons are worth naming too, because no tool page should pretend they do not exist. If the document is a signed, deposited or officially issued record, it was archived precisely to show it has not changed. Editing your own copy is fine. Editing it and then passing it off as the original is not, and the removed identification is itself evidence that the file was altered.

Our advice to anyone unsure: work on a duplicate and keep the original exactly as it arrived. Storage is cheap, and reconstructing an archival copy you overwrote is not.

Edit it, then archive it again

Going from PDF/A to PDF is best treated as one step in a loop rather than a destination. Clear the flag, make the changes, then convert the finished document back with our PDF/A converter at whichever level you were asked for.

Not sure which level that is? The differences are laid out in which conformance level you need, and the format itself is explained from scratch in what PDF/A actually is. If the re-archived file comes back rejected, the cause is usually typography rather than anything you did here — see the fonts not embedded error. Working from scans, or preparing a university deposit? Read OCR a scan before archiving and saving a Word document as PDF/A.

One last practical note. If the document was password protected as well as archived, this tool will not help — that is a different mechanism entirely, and it needs removing a PDF password instead, assuming the file is yours to unlock.
