UlvixorImage Watermark
Upload an image and add a text watermark (your name, brand, or website) with adjustable position, size, color, and opacity, seeing the result live before downloading. All processing happens in your browser.
How it works
- Select an image from your device using the file picker.
- Type the watermark text and choose its position (corners or center).
- Adjust opacity and font size with the sliders, and pick the color with the color picker.
- The preview updates instantly with every change, drawing the text onto a copy of the image on a canvas.
- Download the result as a PNG.
Use cases
- Add your name or brand to photos before sharing them on social media.
- Protect portfolio or catalog photos with a discreet watermark.
- Mark drafts or preview images before delivering the final version.
- Add an event name or date to photos shared within a group.
Common mistakes
- Expecting the watermark to protect the image against any unauthorized use.A text watermark is easy to crop out or cover up. It's useful as visible attribution or a basic deterrent, not as technical copy protection.
- Choosing a text color that blends into the image's background at that position.Try different positions and colors while watching the live preview; a light color over dark backgrounds (or vice versa) usually reads better.
- Using a font size that's too large on small images, pushing the text outside the frame.Adjust the font size while watching the preview; on lower-resolution images, a smaller size keeps the text fully within the visible area.
Frequently asked questions

Alternatives
Editors like Photoshop or GIMP allow more elaborate watermarks (with images or effects), and some can batch-process a whole folder with a script. This tool is handy for a quick text watermark on a single image, with no editor to install.
