Add a text or logo watermark to your photos with full control over size, color, opacity and position — entirely in your browser. Nothing is ever uploaded to a server.
What is the Watermark Adder?
The Watermark Adder stamps a custom text label or logo image onto your photos to protect your work or reinforce your brand before sharing them online. Choose between a text watermark — with your own wording, font size, color and opacity — or an image watermark using your own logo, scaled as a percentage of the photo's width. A nine-point position grid lets you anchor the watermark to any corner, edge, or the center of the image, and a live canvas preview updates instantly as you adjust the controls so you can see exactly how the final result will look. Everything is rendered with the browser's built-in Canvas API, so your original photo and any logo you upload stay on your device the entire time — nothing is sent to a server, which makes it safe to use on private or unpublished images. The finished image downloads in the same format as the one you uploaded.
How to Use the Watermark Adder
- Drag and drop the photo you want to watermark into the upload area.
- Pick the Text Watermark or Image Watermark tab depending on what you want to add.
- For text, type your wording and adjust font size, color and opacity; for a logo, upload the image and adjust its size and opacity.
- Use the nine-point grid to anchor the watermark to a corner, edge, or the center of the photo.
- Check the live preview, then click Download Watermarked Image to save the result.
