Watermarking runs locally — your photos and logo never leave your browser
About this tool
WRRK's image watermark tool overlays your text or logo onto photos using the browser's Canvas API. Each image is decoded, drawn at full resolution, and your watermark is composited on top with the alpha and rotation settings you choose. The whole pipeline runs locally — your photos and your logo never get uploaded to any server.
Two modes cover the common cases. Textis the right choice for copyright lines ("© 2026 Studio Name"), photo credit, or simple brand names — pick a font size, opacity, color, and rotation. Image mode lets you upload a logo (transparent PNG works best) and set its scale as a percentage of the canvas width, so the same setting looks consistent across images of different sizes.
How to add a watermark (5 steps)
- Pick mode. Choose 'Text watermark' to type a copyright line or brand name, or 'Image / logo watermark' to upload a logo PNG (transparent backgrounds work best).
- Drop your images. Drag JPG, PNG, or WebP photos into the drop zone, or click to browse. Any number of files is fine.
- Style it. For text: set font size, color, opacity, rotation. For logos: set scale (% of width) and opacity. Both modes share a 3×3 position grid for placement.
- Apply. Click 'Apply'. The watermark is rendered on top of every image at full resolution using the Canvas API. Nothing leaves your browser.
- Download. Download files individually, or click 'Download ZIP' for a single archive of every watermarked image.

Frequently asked questions
+−Will the watermark appear on every image in my batch?
Yes. Once you set the watermark text (or upload a logo) and pick position, opacity, and size, click 'Apply' — the same watermark is rendered onto every image in the list. Each output is downloadable individually or as a single ZIP.
+−Can I use a transparent PNG logo as the watermark?
Yes — and you should. Transparent PNGs blend cleanly with photos. The opacity slider then dials back the entire logo so it doesn't dominate. SVG files are not supported by the Canvas drawImage API used in browsers — convert SVG to a transparent PNG first.
+−Is the watermark really removable?
No watermark is uncrackable, but a semi-transparent watermark in the center, or a tiled watermark across the image, is much harder to remove than one tucked in a corner. For maximum robustness, place a logo at 30-40% opacity in the middle of the image — that requires inpainting to remove.
+−Does the watermark scale with image size?
Yes. The text font size is calibrated to a 1500px-wide reference image and scales proportionally — so the same setting looks identical on a 4000×3000 photo and a 1080×1080 social post. Logo size is set as a percentage of canvas width for the same reason.
+−Are my images uploaded anywhere?
No. Both your photos and your watermark logo are processed entirely in your browser using the Canvas API. Nothing is sent to a server — the tool works offline once the page has loaded.
+−Why does my JPG output have a white background where the photo had transparency?
JPG doesn't support transparency. If your source image has an alpha channel, the transparent pixels are filled with white when you export to JPG. Use the PNG output option to preserve transparency throughout.
+−What's the best position for a watermark?
Bottom-right is the most common — viewers expect it there and it doesn't draw the eye away from the subject. For maximum protection from cropping or removal, put a semi-transparent watermark in the middle of the image. The 3×3 position grid lets you pick any of the nine standard anchors.
