Optimizing images reduces page size, which is one of the most effective ways to improve core web vitals and mobile loading speeds.

Before You Begin

  • High-resolution image files (before uploading).

Optimizing Images

  1. Compress images before uploading using tools like TinyPNG or ImageOptim.
  2. Use modern formats like WebP whenever possible.
  3. Use the Image Optimization tool in your dashboard to automate compression for existing library assets.

Best Practices

  • Keep individual images under 200KB for hero sections.
  • Use responsive image sizing so mobile users don’t download desktop-sized assets.
