Files are handled using SSL/TLS encryption and deleted instantly after repair.
Our engine uses advanced reconstruction techniques to rebuild corrupted PDFs.
No software needed. Repair your files directly on your desktop or mobile.
Fix corrupt, damaged, or unreadable PDF files instantly. We rebuild the file structure to make it valid again.
Upload the PDF file that refuses to open or shows errors.
We scan the file for errors and attempt to rebuild the index automatically.
Download your restored document. It's now safe to open anywhere.
We can repair structural issues (headers, XREF tables). However, if the actual data content (images/text) was overwritten or zeroed out, recovery is impossible.
PDFs are complex files relying on an intricate "Cross-Reference Table" (XREF). When this table breaks—due to bad downloads, disk errors, or faulty software—readers can't find the pages.
Our repair engine doesn't just patch the file; it rebuilds the entire file structure. It scans for PDF objects (text, images, fonts) throughout the raw data stream and constructs a new, compliant XREF table from scratch.
We use industry-standard libraries (like QPDF) to ensure the recovered file adheres strictly to the PDF specification, making it readable by all viewers again.
Analyzes raw bytes to recover lost objects.
Automatically repairs corrupt headers and footers.
Files deleted instantly after processing.
PDF corruption is common. It often happens during file transfers (incomplete downloads), due to hard drive errors, or when a PDF creator software crashes while saving.
When a PDF viewer says "The file is damaged and could not be repaired," it usually means the Cross-Reference Table (the map that tells the viewer where every page is located in the file) is broken. Our PDF Repair Tool ignores the broken map and rebuilds it by scanning the file directly.
Most PDF viewers are "lazy"—if the index is wrong, they just give up. Our repair engine is strict but smart. It acts like a forensic investigator:
Cross-Reference Table. The index that points to the location of every object (page, image) in the file.
The end section of a PDF that points to the XREF table. Often the first thing to break.
Reading the file code. We parse the raw bytes to find recoverable data.
Optimization for web viewing. Repairs often linearize the file for faster loading.
If the repaired file has blank pages, it means the visual data for those pages was completely lost or overwritten. We recovered the page structure, but the content is gone.
We cannot repair a file that is also password protected if the password header itself is corrupt.
Your documents are processed in secure, isolated containers and are permanently deleted immediately after processing.
