/01 Adding a watermark to your images
Stamp text or a logo onto a picture, positioned where you want it, with control over size and opacity. Everything happens in your browser, which matters when the images you are protecting are unpublished work.
Apply the same treatment across a set of images to keep them consistent.
/02 Where to place a watermark, and what it can achieve
A corner watermark is easily cropped out; one crossing the subject is harder to remove but competes with the image. Semi-transparent marks across the middle are the usual compromise for proofs and previews.
Be realistic about what this achieves. A visible watermark deters casual reuse and identifies the source when an image is shared onward, but anyone determined can remove it. For work that genuinely matters, treat it as attribution and deterrence rather than protection, and keep your unwatermarked originals safe.
/03 How to add a watermark to a photo
Drop the photo in, then add your watermark as a PNG, ideally a logo or signature with a transparent background. Choose where it sits, set its size and padding from the edge, and lower the opacity until it is visible without competing with the picture. Download the result when the preview looks right.
Blend modes decide how the watermark mixes with the photo underneath. Normal lays it on top as it is. Screen suits a white or light logo on darker photos, because it only ever lightens. Multiply suits a dark logo on bright photos, because it only ever darkens. Overlay pushes contrast and can work on mid-tone images.
To use a text watermark, create the text as a transparent PNG first, in any image editor or even a slide app exported as PNG. Doing it once also guarantees the watermark is identical on every photo you publish.
/04 Making a watermark worth having
A tiny logo tucked into a corner is removed with a single crop, and modern AI removal tools erase simple marks in seconds. A watermark that actually deters reuse sits over part of the subject at low opacity, where removing it means rebuilding real detail. The trade-off is that it is more noticeable to honest viewers too, so match the approach to the risk: portfolio previews and proofs for clients warrant stronger marks than posts on your own social accounts.
Whatever you choose, keep an unwatermarked original safe. A watermark is attribution and a deterrent, not a lock, and it cannot be taken back off a flattened image.
