JPEG is not suited for any image that contains text or sharp lines. This is important because t he probability that a user leaves the first page visited on your site, also called the bounce rate, increases by 32% when the page’s load time goes up from 1 to 3 seconds. Not only will this allow you to save a bit of storage space, but the smaller file size implies that your web page will load much faster than with larger images. It looks good on the screen, and best of all, it’s only 34 Kb in size. That’s why it’s recommended to always save your original image first in a lossless format (ex: in TIFF format) before converting to JPEG.įor instance, the following photo is a JPEG image file: In other words, you’ll lose information that you won’t be able to recover. Importantly, each time you save an image in JPEG format, the file size is permanently reduced. If you edit this image again and save it, you’ll end up with an even smaller file size. If you edit it and save it again, the file size of your JPEG will decrease further and so will the image’s quality. To make it very clear, let’s say you’ve saved a JPEG file. This means that the image quality and file size will decrease if you keep saving the image as JPEG. JPEG is regarded as a lossy compression format. The Joint Photographic Experts Group (hence the “JPEG” acronym) created the compression algorithm that makes JPEG images possible in 1992.
