Add Watermark to Image stamps text or a logo across a photo, in one corner or tiled over the whole frame. A corner mark is unobtrusive and easy to crop out; a tiled mark is intrusive and very hard to remove, which is why proofs use it. Opacity, size, rotation and an outline for light-on-light cases are all adjustable.
A watermark is a deterrent, not a lock. Anyone determined enough can remove one, but the point is to make casual reuse obvious and to carry attribution wherever the file goes.
The choice that matters is corner or tiled. A corner mark is unobtrusive and easy to crop out; a tiled mark across the whole frame is intrusive and very hard to remove, which is why proofs and previews use it. Both are here, along with text or an uploaded logo, full control of opacity, size, rotation and colour, and an outline option that keeps a light mark readable over a light photograph.
A single unobtrusive mark for published work, or a full tiled grid for proofs where removal must be impractical.
Upload a PNG and its transparency is preserved, so only the mark is drawn rather than a white box.
An optional outline and shadow keep a light watermark visible over a light photograph.
A diagonal mark at 30 percent is the proof convention, and both are controls rather than assumptions.
Marking happens in your browser, so unpublished work never leaves the machine to get watermarked.
Drop in the image you want marked.
Type the text, or upload a PNG logo — transparency is preserved.
One corner for something subtle, or tile it across the frame for a proof.
25 to 40 percent is readable without dominating. Download when it looks right.
It deters casual reuse and carries attribution, which is most of the value. It does not prevent theft — a determined person can crop or retouch one out, especially a corner mark.
Tile it for proofs and previews where removal must be impractical. Use a single corner mark for published work, where a tiled mark would ruin the image for the people you want looking at it.
Between 25 and 40 percent. Below 20 it disappears on busy images; above 50 it competes with the photograph itself.
Yes. Upload a PNG and its transparency is preserved, so only the mark itself is drawn rather than a white box around it.
