Quick guide
What can Image Watermark help you do?
Free image watermark generator. Add text or image watermarks with adjustable position, opacity, size. Browser-based, no upload.
Best for
Use this to add a visible text label or small logo to one image, such as an attribution or draft mark. Placement supports four corners and the center. It does not offer tiled marks, multiple overlays, free dragging, or invisible tracking.
How to use it
Upload the base image, then choose text or image mode. Replace the default attribution or select a separate logo. Defaults are bottom right, 0.5 opacity, and 8% size. Adjust placement, size, and text color, inspect the preview, and download PNG.
How to read the result
Output keeps the base image's natural pixel dimensions. Size percentage means font size relative to image width in text mode, but logo width in image mode; these are not equivalent visual sizes. Higher opacity is more opaque, and color affects text only.
Privacy and limits
The base image, logo, and label are composited in browser Canvas. This code has no external image-processing API or material-upload request. The downloaded copy includes the visible mark and original scene; there is no cloud project storage or automatic draft backup.
Long text does not wrap or shrink automatically, and a large or tall logo can exceed the image boundary. Inspect the saved result. Visible marks can still be cropped or edited and do not prevent copying. Image mode requires a logo before downloading.
