About This Tool
Watermarking images is essential for photographers, designers, and content creators who want to protect their work or mark drafts before sharing. Our free online tool lets you add watermark to image files in seconds with full control over the text, size, transparency, color, and placement.
Choose a subtle diagonal watermark for portfolio previews, a bold centered stamp for draft reviews, or a discreet bottom-right label for copyright notices. The opacity slider lets you dial in exactly how visible the watermark should be — from barely noticeable to impossible to miss.
Because the entire process runs inside your browser using the Canvas API, your images are never uploaded to a server. This makes it safe to add watermark to image files that contain personal photos, client proofs, or proprietary designs. There are no file-size limits, no watermarks added by the tool itself, and no daily caps.
