What is SVGO?

Editorial review
SVGO is a Node.js-based tool designed to optimize SVG (Scalable Vector Graphics) files. It works by removing various unnecessary or redundant data from SVG files, such as editor metadata, comments, hidden elements, and default or non-optimal values. This process significantly reduces the file size of SVGs, leading to faster loading times and improved website performance. This tool is ideal for web developers, designers, and anyone working with SVG assets who needs to ensure their graphics are as lightweight and efficient as possible. By automating the optimization process, SVGO helps streamline workflows and maintain high performance standards for web projects. Its open-source nature also encourages community contributions and continuous improvement.
