Fix corrupted PDFs and recover your content
Repair PDF rebuilds damaged documents that refuse to open or throw errors like "file is damaged" or "cannot open document". Corruption happens from interrupted downloads, failing drives, email mangling or buggy generators — and often the actual content is still intact inside, just wrapped in a broken structure. Our repair pass reconstructs the file skeleton (cross-reference tables, object streams) so readers can open it again and recover as much content as possible.
Try repair before giving up on a document
When an important contract or thesis won't open, don't assume it's gone. Structural damage — the most common kind — is very often fully recoverable. Upload the broken file, let the rebuilt version download, and check the result. It's free, so trying costs nothing.

Repair PDF — frequently asked questions
Can every PDF be repaired? ＋
Most structural damage is recoverable, though heavily corrupted files may lose some content.
Can a corrupted PDF really be fixed? ＋
Very often yes. Most corruption is structural — the content survives, and rebuilding the file structure makes it readable again.
What if only part of my PDF is recovered? ＋
Severely damaged regions may be lost, but repair salvages every intact object, which is usually most of the document.
Why did my PDF get corrupted? ＋
Common causes: interrupted downloads/transfers, storage errors, email system mangling, or faulty PDF-generating software.
