Add a Watermark to Photos

A text watermark is the quickest: your name, your website or a line like “© Jane Smith 2026”. To type ©, press Option+G on a Mac, or hold Alt and type 0169 on a Windows number pad.

A logo watermark needs a PNG with a transparent background. The transparency is kept, so only the logo appears; a logo saved on a white background shows up as a white box.

Both are sized as a share of each photo, so they look the same across a batch of different sizes. Text follows the photo’s shorter side, so portrait and landscape photos from one camera get the same size of text; a logo follows the photo’s width.

A good watermark is easy to see without spoiling the photo:

For photos you share online, a name or logo in a bottom corner at about half opacity is a common balance. For client proofs, a tiled watermark can’t simply be cropped off.

Add as many photos as you like: the same watermark goes on every one, in the same proportions, so phone photos and small web images in one batch match. Each keeps its name with “-watermarked” added (holiday.jpg becomes holiday-watermarked.jpg), and two or more download together as watermarked-images.zip. If two share a name, the second gets “-1” on the end, so none are lost.

Settings aren’t saved between visits, so note them down if the next batch should match.

JPG stays JPG and WebP stays WebP, saved at a high 92% quality. PNG stays PNG with no loss at all, and transparent backgrounds are kept. GIF and AVIF images come out as PNG, and iPhone HEIC photos as JPG.

Phone photos stored sideways with a rotation tag come out upright. The copies have no EXIF metadata, so camera details and GPS location are removed; your originals keep theirs.

A watermark shows who a photo belongs to, keeps your name on shared copies, and discourages casual copying.

It can’t stop someone determined. A corner mark can be cropped off, and editing apps, including AI tools, can paint out many watermarks. A tiled one is the hardest to remove, at the cost of covering the picture. Treat it as a deterrent and a credit, not a lock.

Nor does a watermark create copyright: in the UK, as in most countries, copyright in an original photo applies automatically, marked or not.

The watermark becomes part of the copy’s pixels and can’t be taken off later. This tool saves a new file and never changes the original, so keep your originals safe: they’re your only clean copies. To change a watermark, start again from the original.

The watermark is added by your browser, on your own phone or computer. Your photos, your logo and the finished images are never uploaded, which matters for unpublished work and client proofs.

To check, open your browser’s developer tools and watch the Network tab while you add a watermark. You’ll see only this site’s own code and anonymous counts (a page view, and that files were added and downloaded), described in our privacy policy. After your first visit, the tool works offline too.
