Try to recover a corrupted or damaged PDF file — rebuilding the structure and page tree, with page-by-page validation.
This tool rebuilds the file from every object it can find in the PDF, even if the cross-reference table (xref) is damaged — but it can't recover data that no longer exists in the file (e.g. a PDF truncated halfway loses whatever is missing). Password-protected files must first be unlocked in "Remove password". If the file is too damaged for any recovery, consider dedicated data recovery software.
Choose the file that's corrupted, doesn't open properly, or shows errors in other readers.
The PDF's internal structure is analyzed; pages that can't be recovered can be kept blank or removed, depending on the option you chose.
You get a rebuilt version of the file that should open normally in any PDF reader.
It can recover most common cases of structural corruption, but not all damage is recoverable — if a page is too corrupted, you can choose to keep it blank or remove it from the final result, instead of blocking the repair of the rest of the document.
No — an encrypted PDF first needs to be unlocked (with the correct password, using the "Remove password" tool) before it can be analyzed and repaired.
You can choose to keep those pages as they were (even with defects), replace them with a blank page, or remove them from the final document — the choice is always yours before creating the result.
No. All processing happens inside your own browser — the file never leaves your computer or passes through any external server. You can confirm this by disconnecting from the internet once the page has loaded: the tool keeps working normally.
No. PDFsy doesn't ask for sign-up, an account or payment — just open the page and use the tool.
