About Image Watermark

Protect your photos or brand your images by adding a custom text watermark. Control the watermark text, font size, position (9 placement presets or custom), opacity, and color. Preview changes live before downloading the watermarked image. Everything runs in your browser — no upload required.

Use Cases

Protecting photographer portfolios from unauthorised use, branding product photos with a company name, adding copyright notices to creative works, labelling proof images sent to clients, marking draft or confidential images.

How It Works

Draws the image on a canvas, then uses ctx.fillText() to overlay the watermark text. Opacity is set via ctx.globalAlpha, color via ctx.fillStyle, and position is calculated based on the selected preset relative to the canvas dimensions.

FAQs

Can I add an image watermark instead of text?

Currently only text watermarks are supported. Use the Image Cropper or an external tool to overlay an image watermark if needed.

Can the watermark be removed?

Text watermarks rendered with moderate opacity across key areas of the image are difficult to remove cleanly. For strong protection, use higher opacity and position it over the main subject.

Will the watermark print correctly?

Yes. The watermark is baked into the image pixels at the original resolution, so it will appear in prints and all exported copies.
