Repair Corrupted PDF File

I was looking for some tool to repair one of the PDF file but none helped. Some worked but they were licensed and didnt repair entirely.

Then I encountered Ghostscript which can repair corrupted PDF files automatically.

Ghostscript is a suite of software based on an interpreter for Adobe Systems' PostScript and Portable Document Format (PDF) page description languages. Its main purposes are the rasterization or rendering of such page description language files, for the display or printing of document pages, and the conversion between PostScript and PDF files.

Download URL:
Download and install Ghostscript from the location http://www.ghostscript.com/download/


How to Repair:
gswin32c.exe -o repairedfile.pdf -sDEVICE=pdfwrite -dPDFSETTINGS=/prepress sourcefile.pdf

Password protected:
gswin32c.exe -o repairedfile.pdf -sDEVICE=pdfwrite -dPDFSETTINGS=/prepress -sPDFPassword=password sourcefile.pdf

gswin32c.exe is located in the installation directory and normally in C:\Program Files\gs\gs9.05\bin

Example:
C:\Program Files\gs\gs9.05\bin>gswin32c.exe -o repaired.pdf -sDEVICE=pdfwrite -dPDFSETTINGS=/prepress Vasantham.pdf
