About Watermark

Stamp a readable text watermark at any of 7 positions with opacity control.

Enter text, pick a corner (or center), and set opacity. White bold type with a dark stroke stays legible on any background, sized relative to the image so thumbnails and originals both read well.

Visible watermarks deter casual theft, not determined removal — register copyrights that matter. Files stay in your browser.

Where it is used

Frequently Asked Questions

Which position protects best?
Center — hardest to crop out. Corners protect least but intrude least; match strength to risk.
What opacity should I use?
40–70% for previews, 15–30% for elegant branding. Below 10% it vanishes on bright areas.
Can watermarks be removed?
Yes, with inpainting tools. They deter casual misuse and prove provenance socially, not forensically.
