Use the below tools to improve a website's page speed.
Test how well the CSS delivery of a web page is optimized and subsequently learn how to improve it.
Automatically compress CSS scripts and files to a much smaller file size. Minimizing the file size improves page speed.
Check if your website has gzip or Brotli compression enabled and how well it compresses your web files.
Test a website to find unoptimized images and learn what you can do to optimize the images for better page speed.
Minify the file size of PNG images to speed up page loading times.
Compress JPEG images to the smallest size to improve page speed.
Combine multiple images to one image file to reduce the number of HTTP requests.
Check which files are cached on a website and by which method.
Check a web page for broken links, images, scripts, etc.. so you can replace/remove them from.
Check how many (and which type of) HTTP requests a web page makes. Reduce requests to improve page load times.
Encode web files to a Base64 string to reduce the amount of HTTP requests that are being made by a web page.
Remove line breaks and unnecessary whitespace to minify web files (ie. HTML) and reduce the file size.
Test whether a website's server has keep-alive enabled.
