Recover PDF Files That Won't Open
A PDF can become damaged when a download or email attachment is interrupted, when a program crashes while saving, or when a storage device fails. Such files often refuse to open or show an error. This tool scans the damaged file, rebuilds its internal structure — the cross-reference table and the page tree — and saves a clean, standards-compliant PDF.
If part of the file is missing, the pages that survived are recovered and the rest is dropped. The repair happens on our server: your file is uploaded, rebuilt and streamed back to you for download.

Frequently Asked Questions
Is this PDF repair tool free?
Yes, repairing PDF files is completely free.
Can every damaged PDF be repaired?
Most structural damage can be fixed completely. If part of the file is missing (for example, an interrupted download), only the pages whose data survived can be recovered. A file that contains almost no PDF data at all cannot be restored.
Is my file kept private?
Files are transferred over an encrypted connection and processed on our server. Uploaded files and results are stored for 48 hours, so you can download the result via its link, and are then deleted automatically. You can delete them yourself at any time with the delete button in the “Your files” list.
Is there a file size limit?
Yes, uploaded PDF files must be 1 GB or smaller.
