Watermarks help protect ownership of photos and graphics shared online, discourage unauthorized reuse, and add branding to shared images.
No. The watermark text is drawn on top of the original image at full resolution — the underlying photo quality is unaffected.
Yes. Select "Tiled" as the position to repeat the watermark text in a grid pattern, which makes it much harder to crop out.
No, everything is processed locally using the Canvas API — your image never leaves your browser.
This tool lets you add a customizable text watermark to any image directly in your browser — no software, no signup, and no uploads to a server. You control the watermark text, position, font size, color, and opacity, then download the result as a full-resolution PNG.
Watermarking is a simple, low-effort way to protect creative work shared publicly online. Photographers, designers, and content creators commonly add a subtle watermark — a name, logo text, or website URL — to portfolio previews, social media posts, and stock samples, making it harder for others to claim the work as their own or use it without permission. A watermark doesn't prevent copying outright, but it does make casual misuse more visible and less appealing, and it reinforces attribution wherever the image circulates.
Once you upload an image, it's drawn onto an HTML canvas at its original resolution. Your watermark text is then rendered on top using the settings you choose — position, size, color, and opacity — using the canvas's native text and transparency rendering. The final combined image is exported as a PNG file you can download immediately, with the watermark permanently baked into the pixel data.
All watermarking happens locally in your browser using the Canvas API. Your original image is never uploaded to a server, keeping unpublished photos and designs completely private until you choose to share them.
The tool draws the uploaded image onto an HTML5 canvas element at its native pixel dimensions, then calls fillText() with the chosen font, color, and globalAlpha value to composite the watermark directly into the pixel buffer. Because the text is rasterized onto the same canvas as the image — not layered as a separate HTML element — the exported PNG contains a single flattened image with no editable overlay, which is what makes the watermark difficult to strip out with simple cropping or layer removal.
Adding a watermark manually in a desktop editor like Photoshop or GIMP means creating a text layer, positioning it, setting blend mode and opacity, then flattening and exporting — a process that takes several minutes per image and requires installed software. This tool collapses that into adjustable sliders and a live preview, so the same result takes seconds and works from any browser, including on a phone, without installing anything.
The tiled mode repeats the watermark text across the entire image in a grid rather than placing it once in a corner. This is the strongest protection option available here: because the watermark appears dozens of times at regular intervals, no single crop can remove it without destroying most of the image content. It's the right choice for preview images, stock samples, or any photo you specifically don't want reused even in part.
A light color such as white or pale yellow typically reads best on darker photos, while black or dark gray stands out better on bright backgrounds. If an image has mixed tones, a mid-opacity gray often stays legible across both light and dark areas without needing to pick a single best-contrast color.
People looking for this feature often search for phrases like "add text to photo online," "copyright stamp image free," "how to watermark photos for Instagram," "bulk watermark alternative," and "protect photos from theft online." This tool covers the single-image text watermarking case for all of these without requiring an account or software download.
