PDF recovery
Recover readable structure from damaged PDF files
PDFPA uses tolerant parsing and document rebuilding to recover what remains readable, then validates the rebuilt output before download.
Readable content recovery
Keeps pages, text and images that can still be interpreted from the damaged source file.
Automatic workflow
There are no object-table or command-line settings to configure; upload the file and start the repair attempt.
Validated repaired output
The rebuilt PDF is reopened and checked before the repaired result is offered for download.
How to repair a corrupted PDF
Upload the damaged file, run automatic recovery and download the rebuilt copy when recovery succeeds.
Upload the damaged PDF
Choose one PDF up to 200 MB. The file must still contain enough recognizable PDF data for recovery to begin.
Run automatic repair
PDFPA analyzes readable objects, rebuilds document structure and verifies recovered pages.
Download the repaired copy
If recovery succeeds, save the validated PDF during the temporary result window.
Temporary processing with automatic cleanup
Your file is processed temporarily to create the requested result. Normal completed results remain available for up to 10 minutes and are then removed automatically.
Short result window
Uploaded and generated files are temporary processing files rather than documents stored in a permanent public library.
Delete when finished
Use Delete result on the completion screen if you want to request removal before automatic cleanup.
Corrupted PDF recovery
Repair damaged PDF structure when the original file no longer opens correctly
A corrupted PDF may fail to open, show missing pages or report structural errors. PDFPA attempts to rebuild recoverable document structure so readable content can be saved into a new PDF without changing the damaged source.
PDF repair is recovery, not reconstruction from nothing
PDF files contain internal objects and references that tell a reader where pages and resources are located. If those structures are damaged, some readers may fail even when useful content remains. A repair tool can sometimes recover readable objects and rebuild the surrounding structure.
No software can recreate data that is physically missing or overwritten. If a file was truncated or important objects no longer exist, the repaired document may contain fewer pages or incomplete elements. PDFPA therefore treats repair as best-effort recovery.
Keep the recovered copy separate from the damaged original
PDFPA creates a separate repaired file, letting you keep the original for comparison or another recovery attempt. After repair, check page count, text, images and other important content before relying on the result.
There is currently no daily repair quota. Each attempt supports one PDF up to 200 MB, subject to normal anti-abuse safeguards. Completed repair files are temporary and expire after the standard result window.
