Scanning objects and rebuilding the cross-reference table
A PDF that won’t open — an error about a broken file, a missing cross-reference table, or a document that just shows blank pages — usually has all of its content intact. What broke is the index: the xref table that tells the viewer where each object lives inside the file.
Drop the damaged PDF here: Rollphy scans the raw bytes for every object, rebuilds a fresh cross-reference table and trailer, and hands you back a structurally valid document — junk before the header gets sliced off, and the report tells you exactly what was fixed. The whole repair runs in your browser; the file never leaves your device.
Recovery is content-preserving: pages, fonts and images are untouched because only the index at the end of the file is rebuilt. What can’t be recovered is data that never made it into the file — a PDF truncated mid-download is missing whatever came after the cut.
Frequently asked questions
- What does “repair” actually change in my PDF?
- Only the index. Your pages, text, fonts and images are byte-for-byte untouched — the tool rebuilds the cross-reference table that tells viewers where everything is.
- The PDF says “there was an error opening this document” — will this work?
- That error usually means a damaged xref table or trailer, which is precisely what gets rebuilt here. If the file was truncated mid-download, everything up to the cut is recovered.
- Can you repair password-protected PDFs?
- No — encrypted files are detected and reported, but recovering them would require the password by design.
