A second chance at a broken file

Damaged PDFs can often be rebuilt well enough to open and read.

Rebuilds the file structure

Most unopenable PDFs are structurally damaged rather than empty - the pages are still in there, but the index that points at them is broken. Repair rebuilds that structure.

Recovers what can be recovered

Where parts of the file are genuinely missing, the repair keeps everything that survives rather than refusing the whole document.

Leaves your original alone

The repair works on a copy, so a failed attempt costs you nothing and you can still try other software on the file you have.

When a PDF will not open

A PDF that a reader refuses to open, or opens as a blank document, is usually damaged rather than empty. Interrupted downloads, a full disk during a save, a failed transfer or a storage fault all produce files where the content is largely intact but the structure that points at it is not.

Repair rebuilds that structure and writes out a document a reader can open. It is worth trying before concluding a file is lost.

Your pages, restored in a file that works

What repair can and cannot do

This is recovery, not reconstruction. If a page's data is physically absent from the file, nothing can bring it back, and a document that was truncated part-way through will come back shorter.

Be honest with the result: open it and check that the pages you need are there and readable. A repaired file that opens is not automatically a complete one, and the failure rate on badly damaged input is high.

Repair a PDF in the browser

Nothing to install, which matters when the file will not open in the reader you already have. The repair runs in a browser tab on Windows, macOS, Linux, Android and iOS.

Upload from your device, from a link or from cloud storage, up to 50 MB without an account.

How your PDF is handled

The file you hand over for this is often the one that matters most. These are the terms it is handled under.

Encrypted connection

Uploads and downloads run over TLS with modern ciphers, and personal data is stored in encrypted form.

Nobody opens it

The process is automated end to end. No one reads your document or copies it, and no backup of a user file is kept.

GDPR compliant

QaamGo Web GmbH runs the service under the GDPR. Your copyright stays yours and nothing trains an AI model.

Frequently asked questions about repairing PDFs

Is it free to repair a PDF?

Yes. Repair PDF is free and needs no account. Files up to 50 MB can be processed without registering, and a free account or a paid plan raises that limit.

Can every damaged PDF be repaired?

No. Repair rebuilds a broken file structure, which covers the common cases, but content that is genuinely missing from the file cannot be recovered by anything.

Will the repaired PDF be complete?

Not necessarily. Open it and check the pages you need are present and readable - a file that opens is not automatically a whole one.

Does repairing change the original file?

No. The repair works on a copy, so your original is untouched and you can still try other tools on it.

Why did my PDF get damaged in the first place?

Usually an interrupted download or transfer, a save that ran out of disk space, or a storage fault. The content is often still there; what breaks is the index that points at it.

Is it safe to upload a damaged PDF?

Yes. The upload runs over an encrypted connection and personal data is stored encrypted. Processing is fully automated, so nobody opens your document or copies it, and no backup of a user file is kept. QaamGo Web GmbH, a German company, runs the service under the GDPR.
