How do I remove a watermark from a PDF or image online for free?

Upload your PDF or image, draw a box (or use the brush) over the watermark, pick a fill colour that matches the background — or use the eyedropper to sample the exact colour — then click Remove Watermark. The tool paints over the selected region and gives you a cleaned file instantly.

How does the eyedropper colour picker work?

Click the eyedropper icon in the Fill group, then click anywhere on the page to sample that exact pixel colour. It becomes your active fill colour, so any watermark you paint over blends perfectly with the background — even on burgundy, cream, or tinted letterheads.

Is my file uploaded to a server?

No. All processing happens inside your browser using JavaScript, PDF.js and the Canvas API. Your files never leave your device.
