Add Watermark to PDF

You just finished an important document. A proposal. A contract. A report.

Now you want to share it — but you also want to protect it. Or maybe it's not final yet and you need to label it DRAFT. Or it's sensitive and needs to say CONFIDENTIAL before you send it to a client.

A watermark does all of that in one step.

With fi50, you can add watermark to PDF in about thirty seconds — free, no software, no sign-up. Everything runs in your browser and your file never leaves your device.

What Is a Watermark?

A watermark is text or an image placed on top of your PDF pages — usually semi-transparent so everything underneath is still readable.

You have seen them before:

• CONFIDENTIAL stamped in gray letters across a page
• A company logo sitting faintly behind the content
• DRAFT printed diagonally from corner to corner

Simple. Effective. Takes thirty seconds to add.

Why Add a Watermark to a PDF?

Here are the most common reasons people use a PDF watermark tool:

• 🔒 Protect Your Work — Your name or logo on every page makes it clear who created the document. Great for proposals, designs, and reports you share before a deal is finalized.
• 🚫 Mark It Confidential — Add a confidential watermark to PDF and immediately signal that the content is sensitive. Anyone who opens it knows not to share it further.
• 📝 Label It as a Draft — Sending a version that is not final yet? Add draft watermark to PDF so nobody mistakes it for the finished product.
• 🎨 Brand Your Documents — Your logo on every page keeps your brand visible every time someone opens the file. Use our add logo watermark to PDF feature to stay recognizable and professional.
• ✅ Add a Transparent Watermark — Want a subtle mark that doesn't overpower the content? Use the add transparent watermark to PDF option to keep things clean and readable.

Text Watermark vs Image Watermark — Which One to Use?

fi50 supports both types. Here's a simple guide:

Use a Text Watermark when you need:

• Labels like CONFIDENTIAL, DRAFT, DO NOT COPY
• Your company name or website
• Quick, clean, and customizable text with font and color options

Use an Image Watermark when you need:

• Your company logo on every page
• A signature graphic or branded visual
• Full control over scale, position, and transparency

Not sure? If you just need a quick label — go with text. If you want brand recognition — upload your logo as an image.
