Frequently Asked Questions

What kind of password protection is applied to my PDF?

QuickDropTools applies AES-strength encryption to your PDF, the same standard used by professional PDF tools and trusted by businesses worldwide.

Is there a minimum password length?

Yes. Your password must be at least 4 characters. We recommend using a longer, unique password for sensitive documents.

Does QuickDropTools store my password?

No. Your password is used only during the encryption process and is never stored, logged, or transmitted beyond what is needed to protect your file.

Can the password be removed later?

Yes. The password can be removed using Adobe Acrobat, PDF-editing software, or another online PDF tool — as long as you know the original password.

Is there a file size limit?

The free Protect PDF tool supports files up to 3 MB. Most contracts, reports, and forms fall well within this limit.
