Over the last decade, the popularity of image file formats used on websites has changed significantly. In the past, the JPEG format was dominant, with most images on the web being saved in this format. However, in recent years, other file formats have gained popularity, including SVG:
One of the main reasons for this shift is the increased use of transparent backgrounds in graphics and images. In the past, designers often had to use the GIF format to create transparent backgrounds, but this format had limitations in terms of color depth and image quality. The PNG format, on the other hand, allows for transparent backgrounds and higher image quality, making it a more attractive option for designers.
Another factor contributing to the shift in image file formats is the rise of responsive design. In the past, designers often had to create multiple versions of images in different sizes to ensure that they looked good on different devices. However, the SVG format allows for images to be resized without loss of quality, making it a more efficient option for responsive design.
So, what does this mean for marketers? It’s important to pay attention to the image file formats used on your website and ensure that they are optimized for the best possible user experience. This can be done by using tools like TinyPNG to compress images and reduce their file size.
Tools such as Akamai Image Manager, Smush, Imagify, EWWW, ShortPixel, Optimole, and Image+ for WordPress can be integrated into your existing WordPress site to manage the optimization of image filesize, format and delivery for your audience.
Uniquely, Image+ for WordPress also optimizes image results for marketers, by using AI technology to generate alternative images for split-testing, and comparing the clicks and sales that follow to work out what works best.
By optimizing the image file formats used on your website, you can improve the overall user experience, reduce loading times, and ensure that your images look their best on all devices. This can ultimately lead to increased engagement and conversion, making it well worth the effort.
Akamai Technologies, a cloud services provider, conducted research on the relationship between page loading speed and engagement. The research found that a delay in page loading of just one second can lead to a 7% reduction in conversions, and a 11% decrease in page views. This shows that the faster a page loads, the more likely users are to engage with the content and take the desired action (such as making a purchase). The research also found that nearly half of web users expect a page to load in two seconds or less, and that a one-second delay in page loading can lead to a 16% decrease in customer satisfaction. These findings highlight the importance of optimizing image loading speed in order to improve user engagement and conversion.
In conclusion, the popularity of image file formats used on websites has changed significantly over the last decade. As a marketer, it’s important to use tools to optimize the images used on your website, as this can improve the user experience, reduce loading times, and drive engagement and conversion.
