**Watermark PDF Online Free** is an essential tool for professionals who need to establish ownership or indicate the status of a document. Whether you are adding a "DRAFT" stamp to a preliminary report or placing your company's logo on an official invoice, watermarking serves as a visual copyright notice. It discourages unauthorized sharing and ensures that your brand identity remains attached to your work.
Using ToolForge for watermarking is safer than using cloud-based alternatives. Because our process runs entirely in your browser, your sensitive proprietary documents and high-resolution logos are never uploaded to an external server. This allows you to maintain strict corporate security protocols while still enjoying the convenience of a free online tool.

"Adding a watermark is more than just branding — it's a layer of psychological security that signals the status and handling requirements of a document to all recipients."
To add a watermark to a PDF for free, use the ToolForge Watermark utility. Simply upload your PDF file, choose between a text or image watermark, and customize your settings.

Yes, watermarking your sensitive documents with ToolForge is completely secure because we use client-side technology. Your PDF file and your watermark images are processed entirely within your web browser. This means your private documents are never uploaded to our servers, keeping your proprietary information or personal data strictly under your control on your own local device throughout the entire session.
Absolutely. Our tool supports both text-based stamps and image watermarks. You can upload any common image format like PNG or JPG to serve as your watermark. This is ideal for adding company logos, official stamps, or professional signatures to your documents. You can also adjust the transparency and position of the image to ensure it looks professional and doesn't obscure important document content.
When using a text watermark, ToolForge allows you to customize the content and the transparency level. You can choose from standard positions like Center (Diagonal), Top Left, Top Right, Bottom Left, or Bottom Right. By adjusting the opacity slider, you can make the text prominent enough to be visible while ensuring it remains subtle enough that the underlying PDF text remains perfectly readable for the final recipient.
You can easily watermark a PDF on your iPhone or Android phone by visiting ToolForge in your mobile browser. The mobile-responsive interface allows you to upload a PDF from your phone memory, type your watermark text or upload a logo from your photo gallery, and apply the watermark instantly. The resulting branded PDF is then saved directly to your mobile downloads folder without the need for any app store installations.
Adding a text watermark adds virtually zero overhead to the file size of your document. Image watermarks will increase the file size slightly based on the resolution of the image you upload. If you find your watermarked PDF has become too large, you can use our "PDF Compressor" tool immediately after to optimize the file size while maintaining the visual integrity of your newly added watermark and original content.
Fast, private, and 100% free. Protect your work with custom watermarks.
