Image editor watermark

The tool applies a central watermark to input images with adjustable opacity, size, and rotation. It supports common formats (JPEG, PNG, WEBP) and outputs a final image suitable for posting or sale.
It preserves visual integrity by performing non-destructive processing and using standard alpha blending.
Conceptually, a user provides an image and optional parameters, the system validates inputs, computes the overlay geometry, and blends the watermark onto a new image file. Output includes a downloadable image in the chosen format.
Audience includes photographers, marketing teams, and content creators who publish assets online; the value lies in consistent branding and asset protection across platforms. Unique value comes from a bold central mark that remains legible on busy backgrounds and from presets that speed up batch workflows. Core features include input validation, format support, adjustable size, opacity, rotation, and centered alignment, plus metadata handling and straightforward export.
