In short: Watermarking an image adds semi-transparent text — such as a copyright notice or website name — on top of a photo, either in one corner or tiled across the whole picture.
About Watermark Image
Photographers, shops and creators watermark images before posting them online so that copies carry their name. A small corner watermark keeps the photo clean; a tiled pattern makes it much harder to crop out.
The live preview shows exactly what you will get. Text size is set as a percentage of each image’s width, so a batch of photos in different sizes all get proportionate watermarks. Output keeps the original format (JPG stays JPG at high quality, PNG stays PNG) and metadata such as GPS location is not copied.
How to use Watermark Image
- Choose one or more images.
- Type the text and set position, color, opacity and size; check the preview.
- Press Watermark & download. Several images are downloaded as a ZIP.

Frequently asked questions
Can a watermark be removed?
Determined people can remove corner watermarks by cropping or retouching. Tiled watermarks are much harder to remove.
Can I use a logo image as the watermark?
This version adds text only.
Does it reduce image quality?
JPGs are re-encoded at quality 92, which is visually lossless for most photos. PNGs are lossless.
Are my photos uploaded?
No. Watermarking happens in your browser. You can check this yourself: open your browser’s developer tools, switch to the Network tab and use the tool — no request carries your input.
