Google developed the WebP image format as an alternative to JPEG and PNG for websites. PageSpeed Insights by Google defines it as the "next-gen format" and encourages websites to use WebP (and AVIF) images as they are faster to load due to their reduced file size as compared to other popular formats.
As a result, many popular sites use WebP. So, when you download an image, you may find that it has .webp file extension at the end of the file name.
If you have difficulty working with WebP images in certain applications, we'll show you the easiest ways to convert them to JPG, PNG, HEIC, or other formats on your Mac.
If you own an iPhone 7 and newer or a 2017 iPad Pro, you may have noticed that updating to iOS 11 defaults the Camera app to capturing photos in Apple's new High Efficiency Image File Format (.HEIC files) and videos in the High Efficiency Video Coding (HEVC or H.265) format instead of the ubiquitous JPEG and H.264 media formats.
Pixelmator for Mac was recently updated on Mac App Store with full macOS High Sierra compatibility, including the ability to open images saved in Apple's new efficient HEIF format and integrate with the stock Photos app as an external image editor.
iOS 11 introduced support for modern HEIF and HEVC codecs developed by the Moving Picture Experts Group (not Apple's proprietary formats) that keep high-resolution photos and videos taken with iPhone and iPad from eating up all your available storage. This post tells you more about it.
