Add a Text Watermark Online
Add visible attribution or branding text to photos and graphics directly in your browser.
Realistic Example
A photographer sharing a client preview can enter a studio name and use about 45% opacity so the mark remains visible without completely covering the photograph.
Factors That Affect the Result
Opacity, image brightness, text length, image dimensions and detail behind the watermark affect readability. Very low opacity can disappear on bright areas, while very high opacity can distract from the image.
Frequently Asked Questions
Does a watermark prevent copying?
No. It provides visible attribution rather than technical copy protection.
Can I control transparency?
Yes. Adjust the opacity slider before applying it.
Is processing local?
Yes. The image is processed in your browser.

Using Image Watermarks Effectively
A watermark places visible text or a graphic over an image to identify ownership, branding, status or source. Position, opacity and size determine how noticeable the watermark is and how much of the original image remains visible. A subtle corner mark may preserve the viewing experience but can be easier to crop, while a larger central watermark is harder to remove but may obscure important detail. Keep an untouched original because watermarking permanently changes exported pixels unless the editor uses a reversible project format. Watermarks can discourage casual reuse, but they do not provide complete technical or legal protection against copying. When preparing product photos, proofs or portfolio images, test the watermark on both light and dark areas and choose sufficient contrast without making the underlying image difficult to evaluate.
Methodology and Practical Limits
A watermark is most effective when placement, opacity and scale balance visibility with preservation of the underlying image. A visible watermark discourages casual reuse but does not technically prevent copying, cropping or editing.
