Visit [pdfhub24.com/add-watermark](/add-watermark) 2. Upload your PDF 3. Choose **Text watermark** or **Image watermark** 4. For text: type your watermark text, choose font size, colour, and opacity 5. For image: upload your logo or watermark image (PNG with transparent background recommended) 6. Set position: diagonal (most common), corner, or centred 7. Choose which pages: all pages, first page only, or a page range 8. Download ## Text Watermark Settings That Work Best **For CONFIDENTIAL, DRAFT, SAMPLE stamps:** - Position: diagonal across the page - Opacity: 15–25% (visible but not distracting) - Colour: grey or dark red - Font size: large enough to cross the page diagonally (60–80pt) **For company name branding:** - Position: bottom centre or top centre - Opacity: 30–40% - Colour: company brand colour ## Image Watermark Tips Use a PNG file with a transparent background — this ensures only your logo appears, not a white rectangle around it. If you only have a JPG logo, convert it to PNG first and remove the white background using [pdfhub24.com/remove-bg](/remove-bg). Position in the bottom-right corner is the most professional placement for logo watermarks on business documents. ## Watermarking First Page Only For proposals and reports where you want your logo or DRAFT stamp only on the cover page, select "First page only" in the page range settings. ## Removing Watermarks If you've added a watermark and need to remove it from the final clean version, always keep the original unwatermarked file. Apply watermarks to copies you're distributing, not to your master file.

Frequently Asked Questions
Can I add both text and image watermarks?
Yes. You can add a text watermark, an image watermark, or both simultaneously. Each watermark type has independent position, size, and opacity controls.
Will the watermark affect print quality?
No. Watermarks are added as a transparent overlay layer. The underlying document content, images, and formatting remain at full quality. You can adjust watermark opacity to ensure readability.
Can a watermark be removed after adding it?
Watermarks added by our tool are embedded into the PDF content. While specialized software may attempt removal, a properly configured watermark is difficult to remove cleanly without visible artifacts.
