Repair PDF for researchers
Updated July 2026
Arthize lets researchers and academics repair a corrupted PDF in a private workspace — free, with no watermark. Repairing a PDF rebuilds a damaged file's internal structure, recovering as much readable content as possible from a document that won't open.
Why researchers repair a corrupted PDF
A researcher merges a paper with its appendices, extracts a results table into Excel for re-analysis, and compresses the figure-heavy submission under a journal's upload limit — privately.
Built for papers. Whether it's papers, datasets, appendices, Arthize's repair pdf keeps the work inside your private workspace. Unpublished work and grant applications are confidential; a private workspace keeps them out of public tools.
What matters when you repair a corrupted PDF
Repair rebuilds a PDF's cross-reference table and object structure.
It can recover files that won't open due to interrupted downloads or transfers.
Recovery depends on how much of the file is intact.
