Make Tech Easier: JPG vs. PNG vs. GIF: The Differences Between Image File Formats. “A rose by any other name may smell as sweet, as Shakespeare says in Romeo and Juliet, but if you take a picture of that rose and save it as a JPEG with high compression, you may experience a decline in image quality. It’s no problem, though, since you also have the option to use PNG, TIFF, GIF, SVG, or even a new format like HEIC or WebP. Some of those formats would look great on the Capulet family newsletter, while others would fit in better on Romeo’s blog, so decoding these file types can be pretty useful.”
Hongkiat: 6 Ways to Save WebP Images as JPG and PNG. “Google’s proprietary image format WEBP is arguably better than the standard JPG or PNG format. It creates much smaller file size than JPG and still supports transparency feature of PNG without much loss in quality…. As ideal as it may be, it is still not supported by many image editors and online submission forms. I personally have to deal with WEBP images often in my work, and so I have found many ways to save WEBP images to JPG or PNG with each having its own advantage. In this post, I am going to share my findings with you.”
Digital Trends: JPEG vs. PNG: Which image-saving format is the better one to use?. “In the world of digital imaging, there are two image formats that prevail above all else: JPEG (or JPG) and PNG. At first glance, a single image shown in both formats might seem identical, but if you look close enough, and dig into the data, there is quite a difference between the two images. Further, each format is designed to be used in specific ways to make the most of its strengths and weaknesses. To help you better understand the differences, we created this guide on JPEG vs. PNG to help you know when to use which format.” Good overview.
