About PDF Repair
A PDF that won't open is one of the more frustrating file problems, especially when it holds work you can't easily recreate. Damage can happen during an interrupted download, a failed upload, a crashed program, or a faulty USB transfer. This repair tool tries to rebuild the broken internal structure so you can get your content back.
Upload the damaged file and the tool scans it for corruption, rebuilds the cross-reference table and object structure where it can, and outputs a recovered PDF. Everything happens in your browser, so a sensitive file never gets sent to a server. It's free to use, requires no account, and adds no watermark. Repair isn't magic, but it often rescues files that other viewers reject.

FAQ
Can it recover every corrupted PDF?
No. Repair works best when the page content is intact but the file's structure is damaged. Severely overwritten or truncated files may be unrecoverable.
Will repairing change how my document looks?
The goal is to restore the original appearance. In most cases the recovered PDF matches the source, though heavily damaged areas may show gaps.
Is it safe to repair a confidential file here?
Yes. Processing happens in your browser, so the file isn't uploaded to any server.
Can I use PDF Repair on mobile?
Yes — ToolHub is fully responsive and works on iPhone, Android, tablets and all modern browsers. No app install needed.
