When does a PDF need repair?
PDFs become corrupted from interrupted downloads, broken USB sticks, partial cloud syncs, or buggy software. Symptoms: file won't open, blank pages, "damaged" warnings, encryption errors.
PDF7 runs the file through a standard PDF recovery — fixes the cross-reference table, normalizes structure, and saves a clean copy. Severely damaged files (binary corruption mid-stream) may still be unrecoverable.
A common case: you open a file and get "This file is damaged and could not be repaired," or the download stopped halfway and the last megabytes never arrived. Sometimes a PDF opens but crashes the reader on a specific page, or shows blank where the content should be. Run it through PDF7 first — a rebuilt cross-reference table is often all it takes to get the file open again.

FAQ
Will recovery always succeed?
No. If the file is severely truncated or has binary corruption, parts may be unrecoverable. We do our best — try it and see.
What about password-protected PDFs?
Repair works on encrypted files too, but you may need to re-encrypt after. We don't store or use passwords.
Can I repair scanned PDFs?
Yes. Repair fixes structural damage; image content (scans) is preserved as-is.
Is repair lossless?
Yes when possible — we save with original streams unmodified. Only the file structure is rewritten.
Can every corrupted PDF be recovered?
No — it depends on how much of the file is intact. If the page content streams are still present and only the structure is broken, recovery usually works well. If bytes were lost mid-file or the data was overwritten, those parts can't be rebuilt. The repair is free, so it's worth trying before you give up on the file.
What causes a PDF to get corrupted, and are my files kept?
Corruption usually comes from interrupted downloads or transfers, faulty USB drives and memory cards, incomplete cloud syncs, or software that closed before finishing a save. As for privacy, PDF7 processes everything on our own servers with no external API, and your uploaded and repaired files are deleted automatically after processing.
