Protect PDF
Add strong password encryption
Frequently asked questions
What encryption does PDF protection use on The PDFverse?
AES-256, the strongest encryption in the PDF standard. It's applied by qpdf, an open-source PDF library compiled to WebAssembly so it runs inside your browser. The same password is set as the password to open the file and as the owner password that controls permissions.
Can I recover a forgotten PDF password?
No. The PDFverse never sees or stores your password, and AES-256 has no backdoor. Save the password in a password manager before you close the tab.
Will my protected PDF still have selectable or searchable text?
Yes. The tool encrypts your original document as it is, without converting pages to images. Once the correct password is entered, the file is identical to the original: text, links, images and quality are all preserved, and the file size stays almost the same.
Is my file uploaded anywhere while it's being protected?
No. Encryption happens locally in your browser tab. Neither the file nor the password is sent to a server.
How it works
From file to finished PDF in three steps
2
Processed on your device
Your browser does the actual work using WebAssembly and JavaScript (pdf-lib, pdf.js), the same technology behind offline apps. The file itself never leaves your computer.
3
Download the result
As soon as processing finishes, your browser triggers a normal file download. Nothing is stored on our end — there's no server copy to delete because one was never made.
Real Privacy: Your Files Never Leave Your Device
Unlike traditional online PDF tools, The PDFverse works entirely client-side using WebAssembly and JavaScript. Your documents are never uploaded, stored, or accessed by third-party servers.
Zero Uploads
Not a single byte of your document is sent to any server.
Zero Latency
Instant processing without waiting in cloud queues.
100% Confidential
Ideal for legal contracts, financial sheets and private records.
