Repair PDF for startups
Updated July 2026
Arthize lets startup founders and teams 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 startups repair a corrupted PDF
A founder exports the pitch deck to PDF, merges it with financials into a data-room file, and sends a SAFE for e-signature — without paying for enterprise document software.
Built for pitch decks. Whether it's pitch decks, cap tables, contracts, Arthize's repair pdf keeps the work inside your private workspace. Fundraising materials and cap tables are highly confidential; private processing is critical.
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.
