Optimizing images for without losing quality

People will lose interest and go on if your website takes longer than 2 seconds to load. Do you think I’m crazy? Amazon discovered that every second their pages take to load costs them $1.6 billion in sales.

Your website might be downloaded from space satellites. But people want your site to load at the speed of light and are impatient. So, how can you speed up your website without losing sales?

Check that your images aren’t too large!

One of the most crucial aspects of having a fast website is image optimization. The majority of file sizes are made up of images.

High-quality photographs are essential. But enormous images result in massive files, which slow down your site. Even one uncompressed image can substantially slow down your entire site and irritate the SEO gods… Yes, uncompressed photos harm your SEO.

But, there are a lot of techniques to reduce the size of your images without sacrificing image quality.

Resize Images

The first step is to resize the image to the appropriate resolution. If you’re going to use an image as a full-screen backdrop or a hero image. We recommend making it roughly 2000 pixels big. Keep in mind that website content is typically 900–1200 pixels in width when sizing an image for your page.

On a Mac

To adjust the size of your image, go to Preview > Tools > Adjust size.

On a PC

ImageResizer is a useful software that allows you to resize images by right-clicking. After you’ve downloaded and installed the program. You’ll have many options for resizing your photos.

Choose the correct file format

Each file format has advantages and disadvantages. Knowing which one to use can make a significant difference in the performance of your website. Here’s a quick rundown of the three most common picture file types on the web, as well as what they’re best used for.


  • The most common file type on the internet.
  • Because of the large color palette that the format allows. It’s ideal for pictures and complex visuals.


  • High resolution, but with more colors and depth, the file size can quickly balloon.
  • Has the ability to deal with transparency (great for logo files).
  • Colors in flat patches of color are rendered quite well.


  • The file is really large.
  • Animations are allowed.
  • Unless you’re making short animations, this isn’t a good idea.

Compress your images

Compression is the second step in image optimization. This method passes your image through an algorithm. The algorithm dramatically reduces the size of your image file. For picture compression, we recommend some online programs. Although they all do the same thing, you may prefer to use one over the other. We suggest you try a few of these!

  • TinyJPG | TinyPNG
  • Compressor.io
  • Kraken
  • ImageOptimizer

As a general rule, your image should never exceed 1MB in size. Image file sizes should be in the 70kb-400kb range. (1 megabyte = 1000 kilobytes)

If your image is larger than 1MB when it comes out of the compressor. Check your image size choices or try a different file type (see above). To put things in perspective, the average size of a whole website is only 4MB, so make the most of your limited space.

Use a descriptive filename.

It’s all too easy to fall into the trap of using the default file name from a camera or image download (e.g., IMG 1234). But this isn’t a smart idea.

When it comes to SEO, it’s critical to choose relevant keywords. These Keywords will ensure that your site ranks higher in search results. Not only does Google crawl your website’s text, but it also looks for keywords in the file names of your images.

Use a Content Delivery Network to serve images.

Another wonderful option to improve image quality and site speed is to use a CDN to serve your images to a user.

CDNs use a network of globally distributed proxy servers to serve your cached images to users. They use real-time image optimization. They do this by loading images from cache/proxy servers that are nearest to the users.

This provides users with a faster loading experience by relieving your server of the stress of supplying images. CDNs also use device detection to assess the size and type of images shown to different devices.

Incapsula, imgix, and ImageEngine are three content delivery networks to examine.

To optimize your images for the web, consider using vector images.

SVG are visuals that you can scale to any screen resolution without sacrificing image quality. Vector pictures are ideal for the web since they speed up the page load time. You may easily include these as responsive photos on your website.

For detailed visuals such as digital photography and painting, the SVG file format is not suitable. But it is more suited to images with forms, curving lines, and colors (e.g., icons, logos, and illustrations).

Page size and load time are crucial components to user experience. They should be at the top of any website owner’s radar. One of the simplest ways to improve your site’s load time is to focus on image optimization.
