Low Quality Image Preview (LQIP) and the SVG-based variant SQIP are the two predominant techniques for lazy image loading. What both have in common is that you first generate a low-quality preview image. This will be displayed blurred and later replaced by the original image. What if you could present a preview image to the website visitor without having to load additional data? JPEG files, for which lazy loading is mostly used, have the possibility, according to the specification, to store the data contained in them in such a way that first the coarse and then the detailed image contents are displayed.
