Optimize Fonts
Choose text styles carefully to minimize the number of additional font files needed.

Optimize Images

CSS Imagery
Use image sprites and replace image files with CSS-generated imagery where possible.
File Formats
Save images with the most appropriate file format for the best quality-to-file-size ratio.
Dimensions
Size images appropriately for the context, as well as the screen & device sizes of your users.
Compression
Adjust compression to minimize file size in balance with the desired level of quality.
Meta Data
Remove all metadata from image files, keeping or adding information as needed.
Composition
Select images that can be compressed more aggressively before visual quality is reduced.

Streamline Delivery

HTML Structure
Organize CSS and JavaScript references to prioritize loading initially-visible content.

Jumpstart HTTP connections and download third-party files sooner in the loading process
Web Hosting & CDNs
Use web hosting with low response time, high uptime and servers close to your users
HTTPS & HTTP/2
Set up your domain with HTTPS for security and your web hosting with HTTP/2 for speed.
