Protect your images with a text watermark

A watermark marks your work as your own and discourages others from reusing it without credit. This tool stamps custom text directly onto your JPG, PNG, or WebP images, letting you set where it sits and how visible it is. Add the same watermark to a whole batch in one go. Everything runs locally in your browser, so your originals are never uploaded and stay completely private.

Why use this watermark tool

How to add a watermark to an image

  1. Add your images Drag and drop your photos or click to select JPG, PNG, or WebP files from your device.
  2. Enter your text Type the watermark text you want to stamp onto the images.
  3. Set position and opacity Pick where the watermark appears and how transparent it should be.
  4. Apply and download The watermark is rendered locally onto each image — save the results to your device.

Your images stay private

All watermarking happens directly in your browser. Your images are loaded and re-rendered on your own device and are never uploaded to any server. We collect only anonymous, aggregated usage statistics (such as how often the tool starts or succeeds) to improve it — never your images, filenames, or any personal data.

Verify it yourself: Open your browser DevTools → Network tab and run the tool: no request ever carries your file. Everything happens on your device.

FAQ

Are my images uploaded anywhere?
No. The watermark is applied entirely in your browser, so your images never leave your device.
Can I watermark multiple images at once?
Yes. Add many images together and the same text watermark is applied to all of them in one batch.
Can I add an image or logo as the watermark?
This tool adds a text watermark. You can type any text, including a brand name or copyright notice.
Can I control where the watermark appears?
Yes. You can choose the watermark's position and adjust its opacity so it sits exactly how you want.
Which formats are supported?
You can watermark JPG, PNG, and WebP images, and export the result in the same common formats.
Will the watermark reduce image quality?
The image is re-encoded after the watermark is added. With high-quality settings the change is minimal, and PNG keeps a lossless result.
Is it really free?
Yes. There are no watermarks from us, no sign-ups, and no file-size limits beyond what your device can handle.
