Frequently Asked Questions

Common questions about our PDF repair tool

Our tool repairs: broken PDF structure, corrupted cross-reference tables, damaged object streams, incomplete downloads, disk errors, transfer corruption, and PDFs that won't open. We use 3-layer recovery: structural repair, object rebuild, and visual extraction.
Absolutely! All processing happens 100% in your browser using client-side technology. Your PDF never leaves your device, is not uploaded to any server, and is not stored anywhere. Complete privacy guaranteed.
Yes, if you know the password! Our tool can attempt repairs on encrypted PDFs by ignoring encryption during structural analysis. However, we recommend removing passwords first for best results.
If structural and object repair fail, we attempt visual recovery - extracting readable content as images. This works for severely damaged files. If a PDF is completely unrecoverable, we'll clearly indicate it's unrepairable.
Most repairs complete in 10-30 seconds. Severely damaged PDFs requiring visual extraction may take 1-2 minutes for large documents as each page needs to be re-rendered and rebuilt.
