Λειτουργεί για ελαφρώς αλλοιωμένα PDF. Τα κρυπτογραφημένα PDF πρέπει πρώτα να ξεκλειδωθούν.
A corrupted PDF is rarely your fault. Most often an interrupted download leaves the file incomplete, a faulty transfer (a USB drive pulled out too early, a truncated attachment, a dropped connection) scrambles the data, or a storage error damages the disk where the document was saved. In each case the file's internal structure no longer matches what viewers expect.
The symptoms are easy to spot: the document refuses to open, shows blank pages, or throws an error such as "file is damaged" or "cannot be loaded." To repair PDF files is to rebuild that structure: the tool reads whatever remains usable, rewrites the cross-reference table and saves a clean new file. That is often enough to fix a corrupted PDF and make it readable again without altering its content.
Let's be honest about the limits: this tool fixes light corruption, the kind that affects how the file is organised without destroying the data itself. If the content has been erased, overwritten or deeply truncated, no tool can bring it back. Repairing a PDF does not guarantee that every file can be saved, but it is always worth trying before giving up on a document.
One special case: an encrypted PDF must be opened first. Run it through unlock if you know the password, then try the repair again. Once the file is restored, you can chain compress to make it lighter, or metadata to check and correct its title, author and properties.
On privacy, no sign-up is required and your files are deleted automatically after processing. Your documents are used only to produce your repaired PDF, nothing more.

Download the resulting document in one click — your files are deleted automatically after processing.
Upload the damaged file: the tool attempts to rebuild and re-save it cleanly. This works for light corruption; encrypted PDFs must be unlocked first.
The tool fixes light corruption, such as a damaged file structure that prevents opening. A severely damaged PDF, or one whose page data is lost, cannot always be restored.
If the file is password-protected, unlock it first before running the repair, because the tool needs to access the content to rebuild it. You can then re-encrypt it afterwards if needed.
