PDF is a binary coded format generated by virtual printing of various files. Since most of PDF data is compressed, editing PDF files with a text editor will cause data error, or lose part of the data due to network instability during network transfer, which will cause PDF files to be damaged and corrupt. PDF readers and viewers cannot open or repair those corrupt PDF files and would throw out a few error alerts. PDF Fixer is a free PDF repair utility which fixes corrupt PDF files by restructuring the damaged PDF data, rebuilding XREF tables and then recovers those PDF documents back. Due to PDFTK just fixes PDF metadata errors and Ghostscript can only recreate XREF tables, PDF Fixer can repair PDFs which PDFTK & Ghostscript cannot repair. It restructures the data from the corrupt PDF files, and builds the objects to make PDFs readable again. With the multi-thread feature, this program can fix multiple PDF files at once. Features - Fix unreadable and corrupt PDFs - Fix PDF XREF tables - Export recovered data to PDF files - Auto preview the fixed PDF content - Automatically detecting bad PDF documents - Batch repair multiple damaged PDF files at once - No required Adobe Acrobat installed - Portable version available
