FAQ
Is full recovery guaranteed?
No. The tool fixes structural errors, but severely damaged files may have content that cannot be restored.
What kinds of corruption can be fixed?
Truncated files, broken xref tables, and stream structure errors. Physically overwritten data cannot be recovered.
Why did my PDF get corrupted?
Common causes include interrupted downloads, save failures, and storage media errors. The tool handles most such cases.
Will images and formatting be preserved?
If the underlying data is intact — yes. The tool only restores structure, it does not alter content.
What if the file still can't be repaired?
Try opening it in Adobe Acrobat Reader, which has its own repair feature. If the file is fully corrupted, recovery is not possible without the original.
