Drag and drop a PDF file into the upload area, or click to browse. If the file is password-protected, you will be prompted to enter the current password.
Select whether to add password protection to an unprotected PDF or remove the password from a protected one. When adding a password, enter your desired password and confirm it.
Click Apply to process the PDF. Download the result, which is either a newly protected file or an unlocked version of the original.
Open the downloaded PDF to confirm the password protection works as expected. For encrypted files, you should be prompted for the password on open.
Encrypt any PDF with a password so only authorized recipients can open and view the document.
Files are securely uploaded over an encrypted HTTPS connection, processed on our servers, and automatically deleted once the operation completes.
Unlock password-protected PDFs when you know the current password, creating a freely accessible copy for your records.
Choose from 40-bit, 128-bit, or 256-bit AES encryption. Set separate user and owner passwords with granular permission controls for printing, modifying, copying, annotating, forms, and more.
Encryption and decryption are handled efficiently on our servers, returning your protected or unlocked file within seconds.
Password-protecting PDFs is essential when sharing sensitive documents electronically. Tax returns, financial statements, medical records, and legal documents should be encrypted before emailing or uploading to shared drives. Adding a password ensures that even if the file is intercepted or accessed by an unauthorized person, the content remains unreadable without the correct password.
Removing passwords is equally important in everyday workflows. Many organizations receive password-protected documents from banks, government agencies, and business partners. Once verified and stored securely, removing the password makes these files easier to access internally without repeatedly entering credentials. Archival systems also function better with unprotected files that can be indexed and searched.
Your documents are transmitted over an encrypted HTTPS connection and processed on secure servers. Both the original file and the result are automatically deleted after you download the output. Your password is used solely for the encryption operation and is never stored, logged, or retained by our system.
No. You must provide the current password to remove protection from a PDF. This is by design, as bypassing PDF encryption without the password would defeat the purpose of the security feature.
The tool uses standard PDF encryption as defined in the PDF specification. This provides reliable protection that is recognized by all major PDF readers including Adobe Acrobat, Preview, and Chrome's built-in PDF viewer.
No. Your password is transmitted securely over HTTPS and used only for the encryption operation. It is never logged, stored, or retained on our servers. Both your file and password are purged from memory immediately after processing.
Yes. The tool supports granular permission controls including restrictions on printing, modifying, copying, annotating, filling forms, accessibility extraction, and document assembly. You can set separate user passwords (to open) and owner passwords (to control permissions), and choose from three encryption levels: 40-bit, 128-bit, or 256-bit AES.
Yes. Standard PDF encryption is universally supported by all major PDF readers and applications. The encrypted file will prompt for a password in Adobe Acrobat, web browsers, Preview on macOS, and any other compliant PDF viewer.
