Browse FilesWhat Is PDF Repair & PDF Recovery?
PDF files can become corrupted due to incomplete downloads, storage failures, email encoding issues, or bugs in the software that generated them. Common symptoms include error messages like "Failed to load PDF", blank pages, missing content, or viewers refusing to open the file entirely. A PDF recovery tool like this one helps you repair and recover damaged files.
Our Repair PDF and PDF recovery tool addresses these issues by rebuilding the document from scratch. It first attempts a structure-level repair using pdf-lib — copying every page, annotation, and metadata field into a brand-new PDF with a valid cross-reference table and object tree.
If structure repair fails (e.g. the internal objects are too damaged), the tool falls back to an advance scan that is more lenient with corrupt files. It renders each page at 2× resolution and embeds the result as a high-quality image in a fresh PDF. This recovers the visual content even from severely damaged files and saves the corrupt PDF as a healthy document in a new location.

Features of the PDF Repair & Recovery Tool
Two-stage PDF recovery and repair strategy with detailed reporting
Structure Repair
Rebuilds the PDF's internal cross-reference table and object structure by copying every page into a fresh document, fixing most corruption issues automatically.
Image-Based Recovery
When structure repair fails, each page is rendered at high resolution and embedded as an image in a new PDF — recovering visual content from severely damaged files.
Page Recovery
Recovers all readable pages from the source PDF. The repair report shows exactly how many pages were successfully extracted and rebuilt.
Detailed Repair Report
After repair, see the method used, pages recovered, file size comparison, metadata preservation status, and any warnings — with color-coded status indicators.
Metadata Preservation
Title, author, subject, creator, producer, and keywords are copied from the original PDF to the repaired version whenever possible.
100% Private & Secure
Your PDF never leaves your device. All repair processing happens locally in your browser using pdf-lib and pdfjs-dist. Nothing is uploaded to any server.
