Unlock PDF for developers
Updated July 2026
Arthize lets software developers 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 developers unlock a PDF
A developer converts a Markdown spec to a clean PDF for a stakeholder, extracts text from a vendor PDF to parse it, and archives the release notes as PDF/A.
Built for technical docs. Whether it's technical docs, specs, README files, Arthize's unlock pdf keeps the work inside your private workspace. Internal specs and unreleased docs are confidential; a private workspace keeps them off public converters.
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.
