About this tool

Password-protecting a PDF is useful when a document contains personal, financial, business, or contract information and should not be opened casually by anyone who receives the file. This tool creates a new encrypted copy of the selected PDF, leaving the original file untouched. You can choose an open password for readers and an optional owner password for permissions. Keep the password somewhere safe, because TinyBee does not store it and cannot recover it later.

Common scenarios

Bank statements and records

Add a password before sending statements, invoices, IDs, or archived records by email or chat.

Client document packets

Protect drafts, contracts, reports, or supporting paperwork before sharing with a limited audience.

Internal reviews

Create a protected copy for review while keeping the original unencrypted file on your device.

FAQ

Are passwords uploaded or stored?

No. The password is used in your browser for the current action and is not stored by TinyBee.

Can TinyBee recover my password?

No. Keep your password in a safe place. If you forget it, TinyBee cannot recover the protected file.

Will the original file change?

No. The tool creates a new protected PDF download and leaves your original file unchanged.

Can I control printing and copying?

Yes. The tool includes permission options for printing, copying, and editing support in readers that respect PDF permissions.

Does every PDF reader enforce permissions?

Password opening is widely supported. Permission flags depend on the PDF reader, so treat them as guidance rather than a guaranteed access-control system.

Can I protect an already locked PDF?

If the PDF is already encrypted, enter the current password first. TinyBee unlocks it in memory before creating the new protected copy.
