Why Image Format Matters

Images are often the largest assets on a website. Choosing the right image format can significantly improve page speed, user experience, and SEO.

Different image formats are optimized for different use cases. Some prioritize image quality while others focus on smaller file sizes and faster loading times.

JPG

JPG (JPEG) is one of the most widely used image formats for photographs and complex images.

  • Small file sizes

PNG

PNG uses lossless compression and preserves image quality while supporting transparent backgrounds.

WEBP

WEBP is a modern image format developed by Google that combines excellent image quality with smaller file sizes.

SVG

SVG is a vector image format that scales perfectly without losing quality.
