Frequently Asked Questions
What types of PDF issues can this tool fix?
This tool can fix structural issues such as corrupted cross-reference tables, damaged object streams, and malformed headers by re-encoding the PDF with pdf-lib.
Will repairing change my PDF content?
In most cases, no. The repair process re-encodes the PDF structure while preserving all content. However, some embedded elements may be lost if they rely on unsupported features.
Is my file uploaded to a server?
No. All repair processing happens locally in your browser using pdf-lib. Your files never leave your device.
