Image Optimization
Jul 03, 2026
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
- Compress images before uploading using tools like TinyPNG or ImageOptim.
- Use modern formats like WebP whenever possible.
- 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.
