Reduction of Page Load Time by using Optimized Images

    According to the latest study, the site visitors look for fast rendering on the web. Only 62% of consumers show their willingness to wait for five seconds to load just one page. There are very few visitors, i.e., only 4%, who can wait for 20 seconds or more time before exiting your website.

    It took a long time for a web page with an image to render in a browser when web page images were not generally optimized by compression at the start of the internet. Now, image compression is just one part of a better time-of page load solution.

    Image optimization includes some other methods to improve graphics for

    • reducing load time,
    • lightening pages
    • reducing the load on network resources. (as well as data reduction in connection with mobile data projects.)

    Possibly it is not well-known that while ranking websites, search engines calculate the time for loading a page. If the loading time of a page is high, it will get higher rankings. In return, the custom pages like this offer the visibility of the site to a more significant number of users while, at the same time, building up their experience once they click on the link to your page.

    The structure and layout of the page of your website decide the ways to optimize. These methods include 

    • making the image size smaller
    • using light-image formats
    • reducing the graphics number that a consumer’s browser needs to load.

    Let’s have a look at some of the ways of optimization.

    1.   Image compression

    Some of the most popular raster file formats are .GIF, .PNG, and .JPEG (.JPG). .PNG has replaced .GIF because it (.PNG) was non-patented and in a lossless format. Instead of using a set of individual pixels, try to use vector file formats like .SVG, .PDF, and .EPS because, compared to the raster file format, this format uses graphic and coordinate parameters for the composition of smaller images.

    One method for reducing the page load time is the conversion of raster file formats to vector format, while the quality of the full image is maintained. But one important thing! This conversion is only better for graphics like geometric shapes, not for photographs (because they provide intricate details).

    2. Vector Images

    For creating images, vector images like .ai, .pdf and .eps use graphics and coordinates parameters. The raster images are usually larger than the vector counterparts. Replacing raster images with vector images lessens the page load times. But the quality of the image retains.

    It is helpful for geometrical shapes images but is inappropriate for complex images like photographs. 

    3.   Image caching

    The speed of page rendering boosts up through image caching. Image caching is the image stored on the proxy server. This provides fast access.

    Proxy Caching puts copies of your icon files on the local point of presence (PoP) servers. As they are easily available compared to if they only reside on the original server, the rendering of an image in the consumer’s browser accelerates. Proxy caching can mainly be useful for websites that use multiple images that remain consistent over time and shared between pages (for instance, page header and footers, corporate branding, etc.).

    Nowadays, another widely used thing in the site visitor’s browser is catching images. It restricts repeated HTTP requests and also reduces the number of bits imported for displaying the given image.

    Image optimization and Content Delivery Network (CDN):

    1.   Automated image compression

    Making use of the Content Delivery Network (CDN) allows visitors to your site to link files on an individual basis to enjoy image optimization’s advantages without the need for any of your staff. You can easily determine the balance between page rendering speeds according to the image quality.

    2.   Progressive rendering

    A highly-pixeled image is rendered quickly through advanced CDNs in a browser. Manydifferent shapes take their place in the next few moments; each of them delivers a higher quality one after the other. The viewer thinks that the page load time is reduced.

    3.    Custom rules and policies

    For all proxy servers serving your websites, fully-featured CDNs allow you to set up cache policies. Many of them also allow you to formulate specific rules for specific file groups and file types on a file-by-file basis.
