How to Protect, Watermark & Sign PDFs Online for Free

Securing Your PDF Documents

PDFs often contain sensitive information — contracts, financial data, personal records. Here's how to protect them without expensive software.

Password Protection

Password-based PDF protection on Fluranto is temporarily unavailable while the encryption workflow is being rebuilt.

When to use: Before sending confidential documents via email, sharing contracts, or distributing internal reports.

Removing Password Protection

PDF password removal on Fluranto is also temporarily unavailable while the decryption workflow is being rebuilt.

Adding Watermarks

The Watermark PDF tool overlays text or patterns on your pages:

• "CONFIDENTIAL" — for sensitive documents
• "DRAFT" — for work-in-progress documents
• Company name — for branding
• Custom text — any text you need

You can customize:

• Font size, color, and opacity
• Rotation angle
• Position on the page
• Which pages to watermark

Digital Signatures

The Sign PDF tool lets you add signatures to documents:

Draw your signature with your mouse or touchscreen

Position it on the document

Resize as needed

Adding Page Numbers

Professional documents need page numbers. The Add Page Numbers tool offers:

• Multiple position options (top/bottom, left/center/right)
• Custom formatting (Page 1 of 10, just "1", Roman numerals)
• Start from a specific number
• Skip specific pages

Security Best Practices

• Always use strong passwords (16+ characters)
• Add watermarks to documents you share externally
• Sign documents digitally instead of printing and scanning
• Use Compress PDF after adding security to keep file sizes manageable
