We recommend the “Smart Image Resize – Make WooCommerce Images the Same Size” plugin for adding image watermarks to your WordPress site images. This plugin offers a range of features that can help you create a professional-looking online store:
The plugin’s Lite version allows you to resize up to 150 images, remove unwanted whitespace, set a custom background color, compress thumbnails for faster page load, and choose which images to resize. The Pro version takes it a step further, offering unlimited image resizing, the ability to convert images to JPG format for reduced file size, and the option to use WebP images for faster page load times.
One of the standout features of the Pro version is the ability to insert a watermark on all your images. This can be particularly useful if you sell digital products or want to protect the copyright of the images you publish online, such as photos, pictures, or comic strips. The watermark can include your logo, name, SKU, or any other relevant information, helping to attract new potential customers through search engines and keep your images safe from unauthorized use.
