Is this real encryption or just a setting?

It is real PDF encryption: the content streams are encrypted, and a reader cannot show a single page without the correct password.

What if I forget the password?

The document cannot be recovered — by us or by anyone. Store the password in a password manager before you send the file.

Do all readers respect the permissions?

Compliant readers do. Permissions are enforced by convention rather than cryptography, so treat them as clearly stated intent and rely on the open password for actual secrecy.

Should I send the password with the file?

No. Send the document by email and the password by message or phone, so one intercepted channel is not enough.

Are my files uploaded anywhere?

No. Every operation runs inside your browser tab using JavaScript and WebAssembly. Nothing is transmitted to MyToolyard or any third party, and nothing is stored after you close the tab.

Is there a file size or page limit?

There is no artificial limit — the practical ceiling is your device's memory. Files up to roughly 100MB are comfortable on a modern laptop; very large scanned documents are best processed in smaller batches.

Does it work on a phone or tablet?

Yes. The interface is fully responsive and touch-friendly. Very large documents will be slower on mobile because processing uses the device's own CPU and memory.

Protect PDF with Password — Overview

About this tool

What is Protect PDF with Password?

Protect PDF adds a genuine open password to a PDF: without it the document cannot be read at all, because the page content itself is encrypted rather than merely hidden behind a setting.

You can also set owner permissions that decide what a reader may do once the file is open — printing, copying text, editing content, commenting, filling forms and rearranging pages.

Encryption runs entirely in your browser. Neither the document nor the password is transmitted, which makes it usable for payslips, medical letters, board papers and client files.

Turn off editing and page assembly so a circulated pack cannot be quietly rearranged.
