Why Secure Your PDFs?
PDF security is essential for protecting sensitive information. Whether you need to password-protect a confidential document, remove protection from a PDF you own, or add a watermark to prevent unauthorized sharing, our browser-based PDF security tools handle it all without uploading your files anywhere.
How to Password-Protect a PDF
Use the Protect PDF tool to add a password to your PDF. You can set a user password required to open the document and a permissions password to restrict printing, copying, and editing. This is ideal for sharing confidential reports, legal documents, and financial statements securely with clients and colleagues.
How to Unlock a PDF
The Unlock PDF tool removes password protection from PDFs that you own. If you have a PDF with a known password and want to remove the restriction for easier access, simply upload, enter the password, and download the unlocked version. This works for both open passwords and permissions passwords.
Adding Watermarks to PDFs
The Watermark PDF tool lets you add text or image watermarks to every page of your PDF. Customize the watermark text, font, size, color, opacity, rotation, and position. Watermarks are perfect for marking documents as Draft, Confidential, or Sample to protect your intellectual property from unauthorized use.
Benefits of Browser-Based Security
Processing sensitive PDFs on a server introduces security risks. AIAZH Tools processes all PDF operations locally in your browser. Your confidential documents never leave your device, making it safe to protect, unlock, and watermark sensitive files like contracts, financial records, and legal documents.
