What is PDF Repair?
PDF Repair is the process of fixing corrupted or damaged PDF files by extracting valid content and rebuilding a clean PDF structure. PDF files can become corrupted due to incomplete downloads, file system errors, storage media issues, or transmission errors. PDF repair tools analyze the corrupted file, extract recoverable pages and content, then rebuild a new, clean PDF document.
According to MDN Web Docs, the FileReader API enables reading PDF files in the browser. Our PDF repair tool uses pdf-lib, a powerful JavaScript library for PDF manipulation. The pdf-lib library provides comprehensive PDF processing capabilities that can validate PDF structure, extract valid pages, and rebuild clean PDF documents.
PDF repair is essential for recovering important documents, fixing files damaged during transfer, restoring corrupted archives, and ensuring PDF files remain accessible. PDF repair tools can fix various types of corruption including damaged file structure, corrupted page data, invalid cross-reference tables, and incomplete PDF streams.

Best Practices for PDF Repair
Following these best practices ensures optimal PDF repair results:
Identify Corruption Early
If a PDF file won't open or displays errors, try repairing it as soon as possible. The longer corruption exists, the more difficult it may be to recover content. Early repair increases the chances of recovering all pages and content from your PDF file.
Backup Original Files
Before repairing, make a backup copy of your corrupted PDF file. While our repair tool is safe and non-destructive, having a backup ensures you can try alternative repair methods if needed. Keep the original file until you've verified the repaired version is satisfactory.
Understand Repair Limitations
PDF repair can extract valid pages and content, but severely corrupted pages may be skipped. If a PDF is too damaged (e.g., completely encrypted or binary corrupted), it may not be repairable. The tool will extract all recoverable content and rebuild a clean PDF with what can be salvaged.
Verify Repaired Files
After repair, verify that the repaired PDF opens correctly and contains the expected content. Check that all important pages are present and that text and images are readable. If some pages are missing, they may have been too severely corrupted to recover.
