Watermark Image
Watermark Image — instantly, in your browser, with nothing uploaded.
Drag & drop your image here, or click to choose. Everything runs in your browser — nothing is uploaded.
Add your name, your site or a "DRAFT" marker to an image before you share it. Choose the text, size, opacity, colour and position — including a tiled pattern across the whole image, which is much harder to crop out than a single corner mark.
Frequently Asked Questions
How do I use the watermark image tool?
Drop your image onto the box above, adjust the controls, and the preview updates as you drag. When it looks right, choose PNG, JPG or WEBP and press Download. Nothing is uploaded at any point.
Are my files uploaded to a server?
No. The file is decoded and re-encoded directly in your browser using JavaScript and WebAssembly, and never leaves your device. That is what makes it safe for private photos, client work and anything confidential, and it is why the tool keeps working with your network disconnected once the page has loaded.
Which watermark position is hardest to remove?
A tiled watermark across the entire image, at moderate opacity. A single mark in one corner can be cropped off in seconds; a repeating pattern over the subject cannot be removed without damaging the picture itself.
Is there a limit or a watermark?
No limits, no watermark, no signup and no cost. Because the work happens on your own device there is no server bill to cover, so there is nothing to meter — the only real constraint is your device’s memory on very large files.
Does this work on Windows, Mac, iPhone and Android?
Yes. It runs in any modern browser on Windows, Mac, Linux, iPhone and Android with nothing to install and no account needed. Chrome, Edge, Firefox and Safari are all supported.
