About Repair PDF
Most 'corrupt' PDFs are structurally broken rather than missing content: an interrupted download cut off the cross-reference table, or a tool wrote something slightly out of spec. Two independent repair passes — qpdf's recovery mode, then a full Ghostscript rewrite — rebuild that structure.
Frequently asked questions
What kind of damage can be fixed?
Broken cross-reference tables, truncated downloads, invalid object streams and files written by buggy generators. Content that is physically missing cannot be invented.
Will my content change?
No. Pages, text and images are copied across as they are; only the file's internal structure is rebuilt.
It still will not open — now what?
If both repair passes fail, the data itself is missing or encrypted. Try re-downloading the original.
