Priority: Critical

Impact: Neutral

What issues it may cause​

  • Slower Load Times: Websites using outdated image formats may experience slower load times due to larger file sizes.

  • Higher Bandwidth Consumption: Older image formats require more data to be transferred over the network, which can impact users with limited data plans or slow internet connections.

  • Reduced User Experience: Slower load times due to large image file sizes can lead to increased bounce rates and lower user engagement.

How do you fix it​

  • Convert images to modern formats like WebP or AVIF to take advantage of their superior compression and quality.

  • Use responsive images to serve the most appropriate image format based on the user's device and browser support.
