How do I add a watermark to a PDF?

Open your PDF in the tool, then create a watermark from text or from an image. Apply it to the pages you want, then drag it on the page to set the position, size and rotation. Lower the opacity so it sits behind your text. When the preview looks right, download the file. The whole thing takes under a minute and needs no account.

Is it safe to watermark a confidential PDF here?

Yes. This tool runs entirely in your browser, so your PDF and your logo are opened, stamped and saved on your own device. Nothing is uploaded to a server, stored or scanned, which matters because watermarks usually go on sensitive files. If you want proof, open your browser's network tab and watch: no file leaves.

Will the watermark reduce the quality of my PDF?

No. The tool draws the watermark on top of your existing pages and leaves the original content untouched, so text stays sharp and selectable. An image watermark is placed at the size you set. Nothing behind the mark is re-rendered or compressed, so the rest of your document looks exactly as it did before.

Can I put a watermark on every page at once?

Yes. Apply a watermark to the full page range and it lands on every page in one step. You can also pick a smaller range so only certain pages carry it, and add more than one watermark, for example a logo in the corner and a Confidential mark across the middle of the page.

Can I use my own logo as an image watermark?

Yes. Choose "Create image watermark" and add a PNG or JPG of your logo or stamp. Place it where you want, resize it, rotate it and lower its opacity so it sits lightly on the page. A transparent PNG works best because the page stays visible behind your artwork.

Does it add its own Visual PDF watermark?

No. The only mark on your file is the one you create. Visual PDF never stamps its own branding on your output and never asks you to sign up or pay to remove anything. You download a clean PDF with exactly the text or image watermark you placed, and nothing more.

Can I add a watermark on my phone?

Yes. The tool works in a mobile browser on iPhone and Android, with no app to install. Open your PDF, create a text or image watermark, then tap and drag it on the page to position it. Because nothing uploads, it runs on your phone's own hardware and there is no wait for a file to transfer.

How do I make a diagonal Confidential watermark across the page?

Create a text watermark with the word "Confidential", apply it to the pages, then rotate it to a diagonal and drag it to the center. Lower the opacity so it reads through the text without hiding it. Adjust each setting in the live preview until it looks right, then download the marked PDF.

Add a text or image watermark to your PDF and see it land on the page as you set the position, size, rotation and opacity. Everything happens in your browser, so your file is never uploaded.

Text or your own logo
Type a word like "Confidential" or "Draft" and style it with your own font and color, or upload a PNG or JPG of your company logo. A transparent PNG keeps the page clear behind your mark.
Adjust it right on the page
After you apply a watermark, click it and drag to move, resize or rotate it. What you see on the page is exactly what downloads, so there is no guessing about the final result.
Set the opacity so text stays readable
Turn the opacity down and the stamp sits behind your content instead of hiding it. Rotate it to a diagonal and resize it to fit the page the way you want.
Every page or just a range
Stamp all pages at once, or pick a page range so only certain pages carry the mark. Add more than one watermark in a pass: a logo in the corner and a note across the middle.
Reusable watermark templates
Build a watermark once and it becomes a template you can apply to any pages in one click. Change the template later and you can update every page you already stamped in one step, so a logo or Confidential mark stays consistent.
Your document never leaves your device
Watermarks usually go on confidential files, so yours is opened, stamped and saved in your browser. Nothing is uploaded, stored or scanned. Open your network tab and check. No file leaves.

How to add a watermark to a PDF

Open your PDF
Drop your PDF into the box or pick it from your device. It opens straight in the editor with no upload and no waiting, however large the file is.
Create your watermark
Choose text or image. For text, type the words and set the font, color and opacity; for an image, add your logo or stamp. Each one becomes a reusable template you can apply again.
Place it and set the look
Apply the watermark to the pages you want, all of them or a range, then drag it on the live page to move, resize and rotate it. Add a second watermark if you need a logo and a note on the same page.
Download your file
When the preview looks right, download the watermarked PDF. Only your device ever touches the file, and no Visual PDF branding is added to it.

Watermark PDF questions

When to add a watermark to a PDF

Mark a document confidential

Before you email a contract, payslip or internal report, stamp "Confidential" or "Internal Only" across the pages. A low-opacity mark reminds every reader not to forward or print the file, without getting in the way of the text they need to read.

Brand a PDF with your logo

Add your company logo to a proposal, quote or portfolio so anyone who opens it knows where it came from. It signals the source, adds a note of trust, and makes the file harder to pass off as someone else's work.

Label drafts and samples

Put a "Draft", "Sample" or "Do Not Copy" watermark on work you share for review or preview. Reviewers see the status at a glance, and a bold "Sample" mark makes clear the file is not the final version you deliver on payment.
