Unlock PDF for startups
Updated July 2026
Arthize lets startup founders and teams unlock a PDF in a private workspace — free, with no watermark. Unlocking a PDF removes a known password or usage restrictions from a document you own, so it opens and prints without prompting.
Why startups unlock a 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 unlock pdf keeps the work inside your private workspace. Fundraising materials and cap tables are highly confidential; private processing is critical.
What matters when you unlock a PDF
Unlocking requires the current password — it removes protection you are entitled to remove.
It is used to clear a known password so a file stops prompting on every open.
Arthize does not crack unknown passwords on documents you don't own.
