Repair Corrupted PDFs and Remove Hidden Data
Upload a PDF File
Drop a PDF that fails to open, is missing pages, or needs cleaning before it's shared. The pipeline analyzes its structure, repairs what it can, and applies the sanitization profile you select.

Upload a PDF that won’t open or contains content you don’t want to share; we repair structural damage in stages and strip hidden revisions, metadata, scripts, and invisible text according to your chosen policy.
Repair corrupted PDF files that will not open. The PDF repair tool climbs an escalation ladder of revision rollback, structural repair, cross-reference table rebuild, content-stream salvage, font recovery, and content reassembly, and keeps only a result that passes your checks for page count and readable text. Even when a file is beyond repair, its images, attachments, metadata, text, and form values are extracted and returned to you.
Then the repaired PDF is sanitized: hidden revisions, JavaScript, attachments, and invisible text are removed under a profile such as Public release, Court filing, or Internal share, and a sanitization certificate proves what is gone. A fidelity report explains what was broken and how it was fixed. Uploaded a renamed DOCX or EPUB by mistake? Recovery recognizes the real format and returns the file with the right extension.
How PDF Repair and Sanitization Works
1. Upload Your PDF
Select the PDF file you want repaired, sanitized, or both.
2. The File Is Triaged and Repaired
The file is scanned for damage, then run through repair stages in order of increasing intervention — revision rollback, structural repair, cross-reference rebuild, content-stream salvage, and font recovery. Each candidate is checked against your page-count and text-coverage requirements before it's accepted.
3. Hidden Data Is Found and Removed
The repaired file is scanned for prior revisions, orphaned objects, metadata, embedded attachments, active content, and text hidden in plain sight — invisible, covered, or color-matched to the background. The sanitization profile you pick decides what must be removed; the removal is then verified by re-scanning the output.
4. Download the Repaired PDF and Its Report
You get the repaired and sanitized PDF, any images or attachments recovered from the original file, and a report describing what was wrong, what was fixed, what was removed, and what could not be proven gone.

PDF Repair and Sanitization
Escalating Repair Ladder
Tries the least invasive fix first — revision rollback, then structural repair, cross-reference rebuild, stream salvage, and font recovery — escalating only when the simpler stage doesn't meet your page-count and text-coverage requirements.
Configurable Sanitization Profiles
Choose a built-in profile — structural, full, public release, court filing, internal share, or keep attachments — or skip sanitizing entirely.
