Lock PDF files with a password—right inside Chrome.
Lock PDF helps you encrypt PDFs in seconds so sensitive documents stay private when you send, upload, or archive them.
Password protect PDFs fastExport a locked copyPrivacy-first workflow
When you need to lock a PDF, speed matters.
If a PDF is going to email, WhatsApp, a client portal, or cloud storage, it should be protected.
Lock PDF adds a simple “secure it now” step so only the right person can open the file.
Problem
PDFs get forwarded too easily
Once a file leaves your device, it can be shared and opened by unintended viewers—especially in fast-moving threads.
Agitation
One mistake can expose sensitive data
Pricing, bank details, IDs, and contracts become readable to anyone who gets the file. That risk is hard to undo.
Solution
Lock in Chrome, export a protected copy
Set a password, generate a new secured PDF, and share confidently—without switching tools or installing bulky software.
