About Image Watermark
Add a watermark to a photo with this free image stamp tool. Type a caption or copyright name, drop an optional logo, then drag the mark, set size, color, and opacity, and download. Use it to sign a shot, label a preview, or put © your name on a picture before you send it out, without a desktop editor.
Photographers mark proofs. Shops caption a product still. Students label a figure. Collage already lets you put text on a grid; this page is the single-image watermark people reach for every day. Outline keeps pale text readable on a bright sky. Corner presets land a mark quickly; custom drag is there when the subject needs a clear path.
Load a PNG, JPG, WebP, GIF, or BMP, add text or a logo, place the mark, and download. Pair with the EXIF Stripper if you also need GPS gone, or Social Size Crop if the next step is an Instagram or YouTube frame.
Watermarking runs in your browser, so the photo never leaves your device. Use this free online image watermark and copyright stamp whenever you need a private caption on a picture.
