Protect PDF files with a password directly in your browser. Lock documents locally, set permissions, and download without uploads.
Add a PDF, set a password, and protect it locally in your browser-no uploads or watermarks.
Use at least eight characters with a mix of letters, numbers and symbols. If you lose this password, it will be very hard to recover access.
Most PDF readers honor these print/copy/edit flags, but determined users or non-compliant apps can bypass them. For sensitive content, pair with watermarks and access controls.
Waiting for file and password.
Common ways people use this tool.
Clear notes so you know what to expect.
A quick path from upload to download.
A local-first workflow that keeps your documents on your device.
Your PDFs are processed locally. We do not send your files to our servers.
Everything runs in your browser so you stay in control from start to finish.
Results download directly to your device with no waiting or email steps.
This Protect PDF tool allows you to add password protection to PDF files directly in your browser. The encryption process runs locally on your device, which means your document is not uploaded to an external server during protection.
It is designed for users who want a simple way to set an open password and basic viewing permissions before sharing or storing a file.
When you select a PDF and set a password, the file is processed only within your browser session. The original document remains on your device, and the protected version is generated locally.
This approach helps users understand exactly how their documents are handled.
The tool allows you to set a password required to open the PDF. You can also choose basic permissions that many PDF readers respect, such as whether printing, copying text, or editing should be allowed.
These options help reduce casual misuse while keeping the document usable for its intended audience.
This tool is commonly used to protect files such as contracts, reports, invoices, academic documents, and personal records. It focuses on applying standard PDF encryption rather than advanced digital rights management.
The content of the PDF remains unchanged. Only access and permission settings are added.
All steps are completed in the browser.
Password protection helps prevent casual access, but it cannot guarantee complete control once a file is shared. Different PDF readers may interpret permissions differently, and determined users may still find ways to copy information.
This tool is intended for everyday privacy needs rather than high-security or compliance-critical use cases.
This Protect PDF tool is designed to reduce reliance on server-based processing. Encryption happens locally during the session, and files are not transmitted as part of normal operation.
More information about file handling can be found in the site's Privacy Policy and Terms pages.

Permissions are respected by most readers, but they are not the same as DRM.
There is no recovery. The file remains locked without the correct password.
No. Protection happens locally in your browser.
This Protect PDF tool provides a straightforward way to add password protection to PDF files using only your browser. It focuses on clarity, local processing, and predictable behavior rather than complex security systems.
