OpenCart is a free and open source e-commerce platform. It provides various functions for creating and managing an online store, including managing products, categories, orders, payments, shipping, etc.

The Watermark and Webp Conversion module for product images is an additional functionality that can be added to OpenCart.

This module allows you to automatically add watermarks to product images, as well as convert them to Webp format.

Watermarks are small images that can be added over the original product image. They may contain a logo, text or some other graphic elements. Watermarks are used to protect images from illegal copying or use.

Webp conversion is the process of converting images into a more compressed format to reduce file size and improve page loading. Webp is an image format developed by Google that provides good image quality in a smaller file size compared to JPEG and PNG formats.

By using the Watermark and Webp Conversion module for product images in OpenCart, you can easily add watermarks and convert images to Webp format automatically when uploading them to your online store. This will help protect your product images and improve page loading performance.
