Protect every image you upload — text & logo watermarks for the WordPress media library.
Ultimate Watermark stamps text or logo overlays on JPEG, PNG, GIF, and WebP uploads — automatically, on every size, with conditional rules. The free plugin covers automatic watermarking, right-click protection, originals backup, and one watermark template. Ultimate Watermark Pro adds dynamic placeholders, on-the-fly frontend display, WooCommerce integration, advanced rules, batch processing, and unlimited templates.
