Frequently Asked Questions
Can it fix any damaged PDF?
It recovers files whose page content is still intact but whose structure is broken. A file that's truncated or encrypted beyond parsing can't be salvaged.
Will I lose anything in the repair?
Form fields, annotations, and bookmarks may not survive the rebuild — the priority is getting readable pages back. Keep your original too.
Is my file uploaded to be repaired?
No. The whole rebuild happens in your browser; the file never leaves your device.
