Upload an image and stamp a custom text watermark onto it, with control over position and opacity.
A watermark stamped onto a photo or graphic signals ownership and makes unauthorized reuse noticeably less appealing, since removing a well-placed watermark takes deliberate effort. Photographers, designers, and content creators commonly watermark preview or portfolio images before a client has paid or a print has been purchased, discouraging casual copying while still letting people see and evaluate the work.
This tool stamps your chosen text directly onto the image using canvas, with control over both position — a corner, bottom-center, or a bold diagonal watermark across the center — and opacity, letting you balance how visible the watermark is against how much it interferes with viewing the image underneath. A corner watermark at high opacity works well for firmly marking ownership, while a diagonal center watermark at lower opacity is the more common choice for a preview image meant to still be easily viewable.
It's used by photographers protecting portfolio previews shared online, designers marking draft or sample work before final delivery, and content creators adding a consistent credit line or handle to images shared on social media. Because everything renders using canvas locally, your original image is never uploaded anywhere during the process.
