Secure Your Information: When to Protect a PDF
Adding a password is the first line of defense for your sensitive documents. Here's when it matters most.

Protect internal reports, financial statements, business plans, and contracts that contain sensitive company information before sharing.
Personal & Private Files
Secure personal documents like bank statements, medical records, tax forms, or legal papers that contain private, identifiable information.

Your PDF is locked using 256-bit Advanced Encryption Standard (AES), the same powerful encryption trusted by governments and banks worldwide.
3. Secure Deletion After Processing
Your file is uploaded securely, encrypted, and then both the original and protected versions are permanently deleted from our servers after one hour.
The Power of a Protected Document
Encrypting your PDF is the most effective way to control access and ensure confidentiality, giving you complete peace of mind when sharing information.
-
Prevents Unauthorized Access: A password is the digital key to your document. Without it, your file remains a securely encrypted, unreadable block of data.
-
Ensures Confidentiality in Transit: When you email a password-protected PDF, the content remains secure even if the email is intercepted. Only the recipient with the password can open it.
-
Maintains Document Integrity: Password protection signals that a document is a final, secure version, discouraging unauthorized attempts to edit or misuse the information within.
Solve Common Document Security Scenarios
Our PDF protection tool is the easy fix for these common privacy concerns.
The Problem: Emailing a Sensitive Attachment
You need to email a document with personal or financial information, but you worry about it being intercepted or sent to the wrong person.
The Solution: Encrypt Before Sending
Password protect the PDF before you attach it. Then, share the password with the recipient separately (e.g., via text message) for maximum security.
The Problem: Storing Files in the Cloud
You store your documents on a cloud service like Google Drive or Dropbox, but want an extra layer of security for your most important files.
The Solution: Add Your Own Encryption
Password protect your PDFs before you upload them. Even if someone gains access to your cloud account, they still won't be able to open your protected files.
The Problem: Sharing a Report with a Limited Audience
You're sharing an internal report or a paid e-book and want to ensure only the intended recipients can view it.
The Solution: Control Access with a Password
By adding a password, you create a barrier to entry. You can share the link to the file publicly, but only those you share the password with can access the content.
The Problem: Preventing Unauthorized Viewing
You have a final version of a contract on a shared drive, but you only want certain people to be able to open and read it.
The Solution: Lock the Final Version
Password protecting the final PDF ensures that only stakeholders with the password can view the contents, preventing casual browsing by unauthorized team members.
