Is Repair PDF free?
Yes. Repair PDF is free to use with no account, and it runs entirely in your browser.
Does it upload my PDF to a server?
No. The repair runs locally in your browser, so your damaged PDF stays on your device the whole time.
Can it repair every broken PDF?
No. Repair PDF is a best-effort client-side path for mildly damaged files and cannot guarantee recovery of severely corrupted PDFs.
Will the repaired file keep the original structure?
Not always. Recovery may rebuild readable pages into a flatter, more image-like export rather than preserving the original structure.
What if only some pages recover?
On a partial recovery, the tool reports which pages were dropped so you know exactly what was salvaged into the fresh export.
What can repair actually fix?
Structural damage: a broken cross-reference table, a malformed trailer, the kind of corruption that stops a reader opening a file whose pages are otherwise intact.
What can it not fix?
Missing content. If a download was interrupted, the bytes were never written, and no repair can invent them. Download the file again first.
Will my forms and annotations survive the repair?
Not necessarily. Rebuilding the document structure often drops interactive layers: forms, annotations and bookmarks are the first to go, and the pages are what is being saved.
The PDF opens but some pages are blank. Did the repair fail?
It succeeded structurally, which is why it opens. Blank pages mean the content for them was damaged or absent. Check every page rather than assuming an opening file is a complete one.
Can it repair a password-protected PDF?
Not while it is locked. Remove the password first, if you have it.
Is the damaged file uploaded to a server?
No. The repair runs in your browser, so a document too broken to open is not also a document you have handed to somebody else.
