Attempt to recover readable pages from a damaged PDF by re-parsing and rebuilding the file. Recovery depends on how much original data remains. Runs privately in your browser.
Try to recover a PDF that will not open, by re-parsing the file and rebuilding the pages that can still be read.
No, and no repair tool can promise otherwise. It recovers pages whose data survives in the file. If the content was truncated or overwritten — a failed download, a bad transfer — that part is gone and cannot be reconstructed.
No. Your damaged original is not modified; the repair produces a separate file, so you can always try something else.
No. The repair runs in your browser.
