Why choose Ultimate Watermark

Unlike basic watermark plugins, Ultimate Watermark gives you:

  • Automatic backup & restore — originals are saved before watermarking; one click and every image is back the way you uploaded it.
  • Native WooCommerce support — bulk-watermark all product images, including gallery and variation images.
  • Professional positioning — 9 anchor points, pixel/percentage offsets, rotation, opacity, scale, custom dimensions.
  • Photographer-friendly — EXIF and IPTC metadata are preserved; image quality settings are honoured per format.
  • Conditional rules engine — apply different watermarks based on image size, post type, file size, dimensions, orientation, user role, post category, product category and more.
  • Non-destructive on-the-fly mode (Pro) — watermark how visitors see the image without ever touching the file on disk.
  • REST API & developer-ready — proper hooks, filters and PSR-4 architecture so you can extend or integrate with any custom workflow.

Core features (Free version)

Watermark types

  • Text watermark — your copyright string, brand name, URL, or any custom text
  • Image watermark — upload a PNG/JPG/SVG logo, signature, or stamp
  • Per-template font, weight, style, decoration, color, and opacity
  • Rotation, scale, and pixel-level positioning

Application modes

  • Automatic — watermark every image as it’s uploaded to the media library
  • Bulk — watermark hundreds of existing images from the Media Library at once
  • Manual — watermark a specific image from its attachment screen
  • Frontend uploads — watermark images submitted from frontend forms

Conditional rules

Choose exactly which images get a watermark with rules built in plain English. Combine conditions with AND/OR logic:

  • Image size (thumbnail, medium, large, full, plus your theme’s custom sizes)
  • Post type (posts, pages, products, custom post types)
  • File type (jpeg, png, gif, webp)
  • File size, image width, image height
  • Orientation (landscape / portrait / square)
  • Aspect ratio
  • User role
  • Post category
  • Product category & product tag (when WooCommerce is active)
