Recovery workflow
Repair is a recovery attempt—always verify the result
A damaged PDF can fail in one viewer and work in another, or lose structure while still looking acceptable. A repaired file should therefore be treated as a recovered copy that deserves a quick visual and page-count check.
- PDFs that refuse to open
- Files that fail during conversion or printing
- Legacy PDFs that need to enter a modern workflow
- First, middle and last pages
- Page count and bookmarks
- Images, fonts, forms and links that matter to the job
Keep the original file. If the recovered version is important, compare the two before deleting the source.

A human tip
The useful version of Repair Pdf
A conversion tool is most valuable when it removes the work around the conversion. People usually arrive with a destination in mind—an upload, a submission, an email, a report, a website or another editing step. The page should make that destination obvious, keep the interface focused, and offer a sensible next action when the first operation is only part of the job.
