About the Add Watermark Tool
Protect your creative work, brand your marketing images, and establish copyright ownership by adding professional text watermarks to your photos and graphics. DCPIXEL renders the watermark directly on the image canvas with adjustable opacity, size, position, and color — all in your browser with no server upload.
100% Private — Processed in Your Browser
Every file stays on your device. DCPIXEL processes images entirely using the browser's built-in Canvas API and WebAssembly — zero server uploads, zero data collection.
Free — No Account, No Limits
DCPIXEL is completely free with no daily limits, no watermarks, and no registration. We never process your files on our servers, so we can offer this permanently at no cost.
