This will reduce the file size without significantly affecting the quality of the image.
Use a Web-Friendly File Format Like
JPEG or PNG instead of GIF or Bitmap file formats will compress images more effectively than others.
Reduce the Dimensions of Your Images
If an image is 2000×2000 pixels, it will be larger in file size than an image that is 1000×1000 pixels. Reducing the dimensions of an image will not affect its quality as much as compressing it.
Optimise Your Plug-Ins
Make sure your plug-ins are properly optimised to reduce loading times.
Use Caching Plugins When Possible
Caching plugins can help speed up loading times by caching your website’s data locally on the user’s computer.
Adding flash content to a website can make it more interactive and engaging for users. However, reducing flash content can significantly improve your website loading time. Due to its big file size, flash content takes longer to load than other types of content.
In order for your website to load faster, you should opt for HTML5 as a replacement for your flash content.
One of the most important things you can do to minimise the page load time is to limit the number of redirects your website uses. Redirects lead to more HTTP requests, which can add up to a slower loading speed.
Although sometimes redirects are needed for your site. But if it comes to the point that the number of redirects is more than what is optimal, it’s always best for you to try to avoid them whenever possible, and one way is by quickly fixing any links that are broken.
The goal of your website is to keep your visitors engaged in order for them to remain on your site and to provide them with what they are looking for, in hopes that they will ultimately result in becoming a customer or executing the conversion you want them to take. So try to avoid having any broken links.
Minifying code can have a significant impact on website performance. Minifying involves removing whitespace and code that’s no longer needed so you can decrease the time it takes for them to load in the browser.
This can add up to helping your website load more quickly, which can improve user engagement and reduce bounce rates altogether. Moreover, minifying code can also help reduce bandwidth usage.
Below are some of the tools that can help you minify CSS, JavaScript and HTML files:
JSMin
UglifyJS
Microsoft Ajax Minify
HTMLMinifier
