Frequently Asked Questions
What types of PDF corruption can be fixed?
This tool is effective for PDFs with structural issues like incomplete cross-reference tables, invalid object pointers, or corrupted metadata. It works best on files that partially open but show errors, not files with binary corruption in image or font data.
What if the repair fails?
If the core page content data is corrupted, even advanced desktop tools may not be able to recover the file. Try opening the PDF in different readers (Adobe Acrobat, Foxit) or contact the file sender to request a new copy.
