How to add a watermark to an image online

  1. 1

    Upload your image

    Choose an image from your device or drag it into the watermark tool. Common formats like JPG, PNG, and WebP are supported.

  2. 2

    Set your watermark text and style

    Enter the text you want, then adjust size, color, opacity, and placement until the watermark looks right for the image.

  3. 3

    Apply the watermark and download

    Save the watermarked image when it is ready. The process happens in your browser, so you can watermark images without uploading them to a remote service.

Understanding the settings

Watermarks work best when they are visible enough to deter casual reuse but not so heavy that they ruin the image itself. Position, opacity, and contrast matter more than flashy styling. For portfolio, product, or proofing workflows, a clean consistent watermark usually looks more professional than a large aggressive overlay.

Compatibility, privacy, and limitations

Browser and device support

These tools are designed for modern browsers. Actual speed and maximum practical file size depend on device memory, processor speed, and how much media your browser can safely keep in memory during processing.

Format safety

If you are unsure which output to choose, start with broadly compatible formats such as JPG, PNG, WebP. They are usually the safest fallback for everyday sharing and playback.

Privacy explanation

This tool keeps image work on your device using browser-native processing where possible, which is useful for screenshots, photos, and design assets that you do not want to upload to an external server.

Things to keep in mind

  • Very large files can take longer to inspect and process because browsers have less memory headroom than native desktop editors.
