Adding a text watermark helps protect ownership when sharing photos, portfolio work, or preview images online. This tool overlays your chosen text onto an uploaded image with adjustable opacity and position, all rendered directly in the browser.
Because it works with the canvas API, the watermark becomes part of the pixel data in the downloaded file, not a separate layer that could be removed by re-saving.
Try a lower opacity for a subtle brand mark, or higher opacity for a clearer deterrent against unauthorized use.
Because everything runs locally in your browser, results appear instantly and nothing you type or upload is ever sent to a server.

This kind of task shows up constantly in everyday writing, coding, design, and admin work, which is exactly why a dedicated, focused tool saves so much back-and-forth.
A tool that does one job well, without a cluttered interface or unrelated features competing for attention, tends to be faster to use than a heavier all-in-one app.
If you find yourself needing this conversion or calculation often, keeping this page open in a tab is usually faster than digging through a bigger software suite's menus.
Because there's no sign-up or installation step, you can jump straight from search result to working tool in a couple of seconds.
Frequently asked questions
Can I use a logo image instead of text?
This tool currently supports text watermarks only; for a logo overlay, an image editor with layer support would be needed.
Does the watermark reduce image quality?
No, only the added text pixels change — the rest of the image keeps its original quality.
