Frequently Asked Questions
Can this browser tool fix unreadable cross-reference tables or broken streams?
Not currently. This interface serves as an upload and preview staging workspace while deep byte reconstruction algorithms are being finalized. It does not rebuild corrupted binary streams.
What alternatives can repair severely damaged PDF files?
Command-line utilities such as qpdf (with the --repair flag) or Ghostscript (pdfwrite) are recommended for reconstructing broken xref tables and unreadable xref offsets.
Does uploading a file here send broken documents to third-party servers?
No. File selection and UI validation execute locally in your browser memory with zero network uploads.
