Image Watermark
Stamp a text watermark onto your image. Runs entirely in your browser.
Sharing photos, portfolio pieces, or product mockups publicly often calls for a visible watermark to discourage unauthorized reuse and mark ownership. This tool draws your chosen text onto the image at the position, size, and opacity you set, rendered directly on a canvas in your browser. It's a lightweight alternative to a full editor when all you need is a single text stamp - for a full logo or image-based mark on a PDF instead, see PDF Watermark.

Common questions
Does it upload my image?
No - watermarking happens locally on a canvas.
Can I use an image or logo as the watermark instead of text?
This tool stamps text only. For a full logo overlay, composite it in an image editor or use the PDF Watermark tool if your output is a PDF.
Can I control how visible the watermark is?
Yes - adjust the opacity slider to make it subtle or bold, and choose its position anywhere on the image.
Does watermarking reduce image quality?
The image is re-encoded once after the text is drawn, so quality stays effectively unchanged at normal settings.
