How to Add a Watermark to an Image
Protect your photos, mark drafts, or brand images before sharing. ImageZen4u stamps any text onto images entirely in your browser.
15–25% for a barely-visible protection mark. 40–60% for a clearly visible brand or copyright notice.
Currently text watermarks are supported. Logo/image watermarks are on the roadmap.
