Frequently Asked Questions
What types of PDF issues can this fix?
Structural corruption, broken cross-references, orphaned objects, and bloated file structure. It cleans and rebuilds the PDF structure using MuPDF.
My PDF shows errors when opening — will this fix it?
It works for many common structural issues. However, if the file data itself is damaged (e.g., from a failed download), it may not be recoverable.
Will the content change after repair?
No. The tool only cleans the PDF structure. Text, images, and formatting remain unchanged.
Is the file size reduced?
Often yes — the repair process also removes unused objects and compresses efficiently, which typically reduces file size.
