Frequently asked questions

How do I repair a corrupted PDF?
Upload the damaged PDF — the tool attempts to rebuild the file structure, recover readable content, and produce a clean working PDF for download.
What causes PDF files to become corrupted?
Common causes include incomplete downloads, interrupted transfers, storage errors, software crashes during save, and virus damage. Partially transmitted email attachments are another frequent cause.
Will repairing a PDF recover all the content?
Recovery depends on the extent of corruption. Minor structural damage is usually fully repaired. Severe corruption (e.g. encrypted with lost key, heavily truncated files) may only allow partial recovery.
Can I repair a PDF that won't open?
Yes — upload the file even if it fails to open in your PDF viewer. The repair tool works directly on the file structure without needing to render it first.
How do I fix a 'PDF file is damaged' error?
This error means the PDF structure is corrupt. Upload the file to the Repair PDF tool. If the file is too damaged, try recovering the original from a backup or re-downloading from the source.
Is repaired PDF quality the same as the original?
If the underlying data is intact, yes. The repair process reconstructs the PDF structure around the original content — it does not re-compress or modify the actual text and images.
