Repairing a PDF attempts to recover and reconstruct the structure of a corrupted or damaged document that does not open correctly. PDFs can become corrupted during transfer, due to storage problems, or because of interruptions during saving.
OnlinePdfEditor analyses the internal structure of the PDF and tries to reconstruct cross-references, repair the xref table, and restore the recoverable parts of the document. The process does not guarantee complete recovery in all cases, but often allows access to the content of otherwise unusable files.
The operation happens in the browser via pdf-lib, without transmitting the file to external servers.
No. Success depends on the type and extent of the damage. PDFs with a partially intact structure have good recovery chances. Severely corrupted files may not be recoverable.
The tool is effective on PDFs with corrupted xref tables, missing headers, damaged streams or interrupted downloads. It cannot recover permanently deleted data.
No. Analysis and the repair attempt happen entirely in the browser. The file never leaves your device.
If local repair fails, try opening the file with Adobe Acrobat (which has a more powerful recovery engine) or a specialised data recovery service.
If the PDF is both corrupted and protected, repair may not be possible without the password. Try unlocking the document first if you know the password.
Free, in the browser, nothing to install. Upload your PDF and go.
