Examples and checks for PDF Repair
Example inputs
- A PDF that will not open at all
- A file that opens to a blank first page
- An email attachment that arrived truncated
Common mistakes to avoid
- Repairing the only copy instead of working on a duplicate
- Assuming every page will come back
- Skipping a page-by-page check of the repaired file
Output checklist
- Confirm the file opens in a normal reader
- Compare the page count with the original
- Scan pages for missing images or blank spreads
A damaged document can still hold sensitive content, so give the repaired copy the same handling as the original and check it before passing it on.

Frequently asked questions
- Is PDF Repair free to use?
- Yes. PDF Repair is available on the free plan with 20 daily runs. Paid plans add higher quotas for repeat work.
- What kind of damage can a structural rebuild fix?
- Mostly a broken cross-reference table or object structure, which is what happens when a download stops early or a reader saves badly. Rebuilding restores that structure so the file opens again.
- Will every page come back?
- Not always. Rebuilding restores the container rather than the content, so pages, images or text that were already unreadable in the damaged file are dropped from the repaired copy.
- Should I repair before or after compressing?
- Repair first. Compression on a broken file tends to fail or produce another broken file, so get a copy that opens reliably and optimize that one.
- What if the repair fails too?
- Some files are damaged past the point where any tool can parse them. Keep the original, ask the sender for a fresh copy, and treat a working backup or a re-scan as the reliable route.
