Image Watermark
Overlay a text watermark onto images.
About Image Watermark
Image Watermark overlays a line of text onto a JPEG, PNG, or WebP image — a name, copyright line, or label baked into the picture. Use it to brand photos before posting or to mark a draft as a proof. The overlay is rendered in your browser, so your originals never get uploaded.

Frequently asked questions
Can I add an image logo as the watermark, or only text?
This tool overlays text. For stamping a logo image onto a PDF instead, see Watermark PDF, which supports image watermarks.
Which image formats are supported?
JPEG, PNG, and WebP, both as input and output.
Is the watermark permanent?
Yes. The text is rendered directly into the image pixels, so it travels with the file and cannot be toggled off afterward.
Are my images uploaded?
No. The watermark is drawn onto the image in your browser. Nothing is sent to a server.
Will the watermark reduce image quality?
Only the area under the text is altered. Re-encoding uses high-quality settings, so the rest of the image is effectively unchanged.
