How to Add a Watermark to a PDF Free Online (No Account)
Stamp any PDF with a text or image watermark online for free — no account, no watermarks added by the tool itself. Works on any device.
Adding a watermark to a PDF online is free with FixMyPDF — no account, no "free tier" limits, and no ironic second watermark added by the tool. Everything runs in your browser, so your document stays private.
How to Add a Watermark in 3 Steps
Go to fixmypdf.in/tools/watermark-pdf. Upload your PDF. Choose text watermark (type your text, set size/colour/opacity) or image watermark (upload a PNG logo). Click "Add Watermark" and download the result. No account needed.
Text Watermark Options
Type any text: "CONFIDENTIAL", "DRAFT", "COPY", "DO NOT DISTRIBUTE", your company name, or any custom text. Choose font size (20–120pt), colour (black, red, grey, or custom hex), opacity (10%–100%), and rotation angle (45° diagonal is most common).
Image Watermark Options
Upload a PNG logo or stamp image. PNG with a transparent background produces the cleanest result — the logo appears over the document content without a white rectangle around it. Set opacity lower (20–40%) so the document content remains readable beneath the logo.
No Meta-Watermark Added
Some free watermark tools add their own branding to your PDF as an extra watermark (e.g., "watermarked with freetool.com" in a corner). We don't. The only watermark on your output PDF is the one you chose.
Privacy — Document Never Leaves Your Browser
Your PDF is processed locally using JavaScript in your browser. No file is uploaded to FixMyPDF's servers. This is especially important when watermarking confidential documents — the content stays completely private during the watermarking process.
Works on All Devices
The same URL works on Windows, Mac, iPhone, iPad, and Android. No device-specific requirements — any modern browser (Chrome, Safari, Firefox, Edge) supports the tool. Open the URL and start watermarking from any device.
After Watermarking
Your watermarked PDF can be compressed for email, password-protected so only authorised people can open it, or split into sections. All free, all in-browser, no account needed.
