Frequently Asked Questions
Is it free?
Yes. No signup required.
Is my file safe?
Yes — your PDF is processed entirely in your browser and never uploaded.
What kinds of problems can this fix?
Many common ones: a broken cross-reference table, invalid or malformed objects, or a file that other viewers refuse to open. We re-read your PDF leniently and rebuild a clean, valid file from what's recoverable.
Can this recover missing or deleted content?
No — if data is truly missing or unreadable (not just structurally broken), no repair tool can bring it back. This works by rebuilding the file's structure around whatever content is still intact.
Why did my PDF stop opening in the first place?
Usually an interrupted download or save, a bug in whatever created it, or an incomplete transfer — any of these can leave the file's internal structure broken even though most of the content is still there.
Are there settings to configure?
No — repair is automatic. Just upload your file and confirm.
