How to Add a Watermark to an Image Online
This tool adds a text watermark to any photo or graphic directly inside your browser — the image is never uploaded, so your work stays completely private.

When you are happy with the result, click download and the watermarked image is saved to your device as a PNG. Use it to protect product photos for your online shop, credit your photography on social media, or mark drafts and previews before sharing them with clients.
