Introduction

Choosing the right image format is essential for optimizing your website’s performance, enhancing user experience, and improving SEO. In this article, we compare three popular image formats—PNG, JPG, and WebP—to help you decide which is best for your website.

Understanding Image Formats

When it comes to web images, PNG, JPG, and WebP are among the most commonly used formats. Each format has unique advantages and is suited for different types of content.

1. PNG (Portable Network Graphics): Best known for its high quality and support for transparency.
2. JPG (Joint Photographic Experts Group): Popular for photographs due to its efficient lossy compression.
3. WebP: A modern image format developed by Google that provides superior compression while maintaining high quality.
