How to Watermark Images to Protect Them in 2026
If you publish photos, artwork or product images online, someone will eventually reuse them without asking. A watermark won't make theft impossible, but it deters casual copying, ensures your name or brand travels with the image, and quietly advertises your work wherever it's shared.
This guide covers what to put in a watermark, the settings that make it effective without ruining the image, what watermarks realistically can and can't do, and how to add one privately in your browser.

Add a text watermark to protect your images.
What to put in your watermark
The most useful watermark text is your name, brand or website URL. A URL is especially valuable because it doubles as free promotion — anyone who sees the shared image knows where it came from. A copyright line like '© 2026 Your Name' adds a clear ownership claim.
Opacity and size: subtle but visible
The goal is a watermark people can't ignore but that doesn't ruin the image. An opacity around 30–50% with a moderate font size usually strikes the balance: the underlying photo stays clear while the mark is plainly there. Too faint and it's easily cropped or cloned out; too heavy and it spoils the image you worked on.
Placement strategy
Placement is a trade-off between protection and aesthetics. A centred, semi-transparent watermark is the hardest to crop out, making it the most protective. A corner placement is less intrusive and looks cleaner but is easier to remove by cropping. Choose based on how much the image is worth protecting versus how prominent you want the mark to be.
What a watermark can and can't do
A visible watermark deters opportunistic reuse and keeps attribution attached to your image. It is not unbreakable — a determined editor can sometimes clone or crop it out — so always keep your unwatermarked originals safe, and place the mark where removal would damage the image. For high-value work, watermarking is one layer of protection, not the whole strategy.
