Add a Watermark to an Image Online for Free
Sharing photos publicly — on a portfolio site, a marketplace listing, or social media — comes with the risk of someone lifting the image without credit. A subtle watermark discourages that and makes clear who the image belongs to, without needing to open a full photo editor every time. This tool stamps a text watermark, like your name, business, or a copyright notice, onto your image directly in the browser.

Add a Watermark to an Image Online for Free
Sharing photos publicly — on a portfolio site, a marketplace listing, or social media — comes with the risk of someone lifting the image without credit. A subtle watermark discourages that and makes clear who the image belongs to, without needing to open a full photo editor every time. This tool stamps a text watermark, like your name, business, or a copyright notice, onto your image directly in the browser.
Type your watermark text into the field above the dropzone, choose where it should sit — any of the four corners, centered along an edge, or dead center — and adjust its opacity so it sits unobtrusively over the image rather than fighting for attention with the photo itself. Lower opacity settings (around 30-50%) tend to work best for a watermark that's visible enough to deter reuse without distracting from the image, while a color picker lets you match the text to whatever contrasts best against your typical photos.
The watermark is drawn directly onto a copy of your image using the Canvas API's text rendering, so it becomes a permanent part of the pixel data rather than a removable overlay — the same technique professional photographers and stock sites use, just without a subscription. Font size scales with your chosen setting regardless of the source image's resolution, so larger source photos may need a larger font size to stay proportionally visible.
Drop in one photo or a whole batch that all need the same watermark text and settings; each is stamped independently and, for multiple files, bundled into a single zip. Nothing is uploaded — watermarking happens entirely on your device.
Common questions
Somewhere around 30-50% tends to work well — visible enough to make casual reuse obvious, but not so bold that it distracts from the photo itself. Bump it higher if you specifically want the watermark to be hard to miss or crop out.
Not on this page — it's built specifically for text watermarks like a name, business, or copyright notice. For a logo or image-based watermark, you'd need a tool that accepts two separate image uploads (a base photo and a logo), which isn't part of this simple text-only flow.
Yes — it's drawn directly onto the image's pixel data using the Canvas API, becoming a permanent part of the downloaded file rather than a removable layer, the same as watermarks applied by professional editing tools.
Yes — drop in as many images as you like with the same watermark text and settings. Each is stamped independently and, when there's more than one, bundled into a single zip download.
No — the watermark is rendered entirely in your browser using the Canvas API. Your photo never leaves your device.
