PDF ロック解除 — Frequently Asked Questions

Do I need to know the password to unlock?

Yes — this tool removes protection from PDFs you already have the password for. We do not crack passwords.

Why would I want to remove a PDF password?

Passwords can be inconvenient for documents you frequently open on trusted devices. Removing it saves time.

Is it legal to unlock a PDF?

Yes — unlocking a PDF you own and have the password for is completely legal.

What if my PDF has permission restrictions but no open password?

Some PDFs restrict printing or copying. Our tool focuses on open-password removal; permission restrictions may vary.

Does unlocking change the PDF content?

No — only the password protection is removed. All content, formatting, and images remain identical.
