Watermark Adder
Stamp text or a logo watermark onto your images.
Runs 100% in your browser — nothing is uploaded
Add a text or image watermark to your photos in your browser — control the text, font size, colour, opacity, position, rotation, and tiling to protect your work or brand it. Batch-friendly and completely private: images are processed locally and never uploaded.
Frequently asked questions
Can I use a logo as the watermark?
Yes. Add a text watermark or upload a logo (a transparent PNG works best), then set its size, opacity, and position.
Is my image uploaded?
No. Watermarking is done on a canvas in your browser, so your photos stay on your device.
Can I tile the watermark across the whole image?
Yes. Choose a single placement in one of nine positions, or tile it repeatedly for stronger protection.
Does it reduce image quality?
The watermark is drawn onto a copy at full resolution. Export as PNG for a lossless result or JPG for a smaller file.
