What it is
The Image Watermark tool writes text over a picture, with control over position, size, colour and transparency.
What a watermark is actually for
It is a deterrent and an attribution, not a lock. Anyone determined enough can crop or paint over it. What it does reliably is make casual reuse inconvenient, and make sure that when an image does travel, your name travels with it.
The two situations where it earns its place: photographs and artwork shared publicly, and documents sent to someone else. Writing "for X purpose only, dated" across a copy of an ID or a proof of address is a genuinely useful habit, because it makes that copy obviously unusable for anything else.
How to use it
- Add the image.
- Type the text and set position, size, colour and transparency.
- Download the watermarked copy.
Getting it right
Transparency is the whole craft. Fully opaque ruins the picture; nearly invisible protects nothing. Somewhere around 30 to 50 percent usually reads without dominating.
Corners are the easiest to remove, because a crop takes them off. A watermark across the middle survives cropping but competes with the subject. For a document copy, across the middle is the right answer; for a photograph, a corner is usually the compromise.
Keep the original. The watermark is written into the pixels and cannot be removed afterwards.
