How to use Image Watermark
- Choose your image.
- Enter the watermark text — a name, a URL, or PROOF.
- Set position, size and opacity, and check it reads against the actual image.
- Download the watermarked copy; the original is untouched.
- A corner watermark is easily cropped; a central one is not, but dominates the image.
- Keep the unmarked original — the watermark cannot be removed from the download here.
- Everything runs in your browser; client work is not uploaded anywhere.
What a watermark is for, and what it cannot do
It attributes and it deters. A visible mark makes casual reuse obviously improper and keeps your name attached as an image travels. It does not protect the image: a determined person can crop it out, clone over it, or these days remove it with generative editing in seconds. Treat it as a signature rather than a lock, and do not let it substitute for sending low-resolution proofs and holding the full-quality file back until you are paid.
Placement, and the crop problem
A mark in a corner is unobtrusive and trivially cropped away. A mark across the centre survives cropping and ruins the image, which is exactly right for a proof and wrong for anything you want seen. The usual compromise for portfolio work is a discreet mark in the lower third, sized so that removing it would visibly damage the composition. For proofs sent to a client before payment, a large diagonal at low opacity across the whole frame is the honest choice — they can judge the picture and cannot use it.
Opacity and legibility
Around 30–50% works for a signature-style mark: readable without competing with the image. The difficulty is that a single colour cannot read on both light and dark areas of a photograph, which is why white text with a subtle shadow, or a mark placed in a deliberately chosen flat area, is more reliable than picking a colour and hoping. Check the result at the size people will actually view it, not at full resolution.
