Why Are My Photos WebP?

Understanding why websites use WebP format and what it means for your downloads

Last Updated: November 12, 2025
Quick Answer

Your photos are in WebP format because websites automatically convert images to this format when you download them. WebP files are 25-35% smaller than JPEG while maintaining similar quality, helping websites save bandwidth costs and load faster for all users.

The Simple Explanation

If you've downloaded images from websites like Google Images, social media platforms, or content delivery networks, you've probably noticed they're saved as WebP files instead of traditional JPEG or PNG. This isn't a bug or mistake—it's an intentional optimization by websites to help:

  • Reduce bandwidth costs - WebP files are 25-35% smaller than JPEGs
  • Speed up loading times - Smaller images mean faster page loads
  • Improve user experience - Pages load faster, especially on mobile
