PDF protection adds a password that is required to open the document. Without the correct password, the file contents are encrypted and completely inaccessible. You can also set permissions restrictions — allowing the file to open freely but preventing printing, copying text, or editing — without requiring a password to view.
Processing happens entirely in your browser. Your document and password are never sent to any server — protection is applied locally on your device.
Use at least 12 characters combining upper and lowercase letters, numbers, and symbols. Avoid common words, names, or dates. Share the password through a different channel than the document itself — if you email the protected PDF, send the password by SMS or phone call to prevent anyone who intercepts the email from accessing the file.
Store the password in a password manager so you can access the document yourself in future. Losing the password means losing access to the file permanently — there is no recovery mechanism for correctly encrypted PDFs.
Sensitive documents shared via email. Contracts, financial reports, medical documents, and personal identification sent by email benefit from password protection. Email is not an encrypted channel — a protected PDF adds a layer of security even if the email is intercepted.
Cloud storage. PDFs stored in shared cloud folders (Google Drive, Dropbox, SharePoint) with broad access permissions can be individually protected so only intended recipients can open them.
Permissions restrictions without a password. Adding edit and print restrictions prevents casual modification in standard PDF viewers, useful for distributing final report versions where you want to discourage unofficial editing.
Archival files. Long-term archive documents containing sensitive historical records can be protected so they require authentication to open even years after creation.
What happens if I forget the password?
The document is genuinely inaccessible without the correct password. There is no recovery mechanism. Always store passwords for important protected documents in a password manager before sharing the protected file.
Can I remove the protection later?
Yes. Use the Unlock PDF tool with the original password to remove protection and download an unprotected version. Keep an unprotected copy in a secure location for your own records.
Is permissions protection as strong as open password protection?
Permissions protection is weaker — it prevents casual misuse in standard PDF viewers but can be removed by someone with technical tools. It signals intent and deters non-technical users. Open password protection with AES-256 encryption is significantly stronger and genuinely prevents access without the correct key.
Is my document uploaded to a server when adding protection?
No. Encryption is applied entirely in your browser using your device's processing power. Your document and the password you choose are never transmitted anywhere. This is particularly important for the sensitive documents that most benefit from protection.
Will the protected PDF open on mobile devices?
Yes. Password-protected PDFs are supported by all modern PDF viewers on iOS and Android. The recipient will be prompted to enter the password when they open the file, regardless of which app they use.

Permissions protection is weaker — it prevents casual misuse in standard PDF viewers but can be removed by anyone with the right tools. It signals intent and deters non-technical users. Open password protection with AES encryption is significantly stronger. Use both for maximum protection of sensitive documents.
Rifix Protect PDF encrypts your PDF with a password using AES-256 encryption — all within your browser. No file is ever sent to a server. Set an open password (required to view the document) or an owner password (restricts printing, copying, and editing). Download the protected PDF instantly.
Password-protecting a PDF is essential when sharing sensitive documents by email or messaging. Contracts, payslips, medical reports, financial statements, and ID scans should always be password-protected before sharing, especially over unencrypted channels.
Upload your PDF — Select the document you want to protect.
Set your password — Enter a strong password. Optionally set permissions to restrict printing or copying.
Click Protect PDF — AES-256 encryption is applied immediately in your browser.
Download — Share the protected file. The recipient will need the password to open it.
Rifix uses AES-256 encryption, the same standard used by governments and financial institutions worldwide. A file encrypted with AES-256 and a strong password cannot be opened without the correct password.
A user password (open password) is required to open and view the document. An owner password restricts what the viewer can do — such as printing, copying text, or making edits — even after the document is opened.
Yes. Use the Rifix Unlock PDF tool with the correct password to remove encryption and restore the original unprotected PDF.
No. Encryption runs entirely in your browser using PDF-lib and the Web Crypto API. Your document never leaves your device, which is especially important for highly sensitive files.
Yes. Completely free, no account required, no watermarks added to the output.
Use a password of at least 12 characters mixing letters, numbers, and symbols. Avoid using the recipient's name, the document title, or common words. Share the password through a different channel than the document itself — for example, send the PDF by email and the password by WhatsApp.
Rifix applies 128-bit AES encryption, the same standard used by most PDF software. This is suitable for protecting confidential business documents.
Yes. You can set an open password (required to view the PDF) and a separate permissions password (restricts printing, copying, and editing).
No. There is no way to recover a forgotten PDF password. Keep a secure record of any password you set.
Yes. Password-protected PDFs open normally in Adobe Reader, Apple Preview, browser PDF viewers, and all standard PDF software.
