FAQ
What kinds of damage can be repaired?
Broken cross-reference tables, wrong object offsets, structural inconsistencies and trailing garbage — the most common corruptions from interrupted downloads or faulty converters.
What if the file is truncated (cut off mid-download)?
If the file lost its structure tables entirely, recovery may be impossible client-side — you'll get a clear error instead of a broken file. Repair fixes broken offsets and cross-reference tables fully; for truncation, re-download or re-export the original.
Is anything uploaded?
No. The repair engine (qpdf compiled to WebAssembly) runs entirely on your device.
Will the repaired file look identical?
Content is preserved; internal structure is rebuilt, which sometimes makes the file even smaller.
