WebP images
WebP is an image format developed by Google and released in 2010. It supports both lossy and lossless compression, transparency and animation in a single format, typically producing files 25-35% smaller than JPEG or PNG at comparable quality. All major browsers and macOS (since macOS 11 Big Sur in 2020) support WebP natively.
Where File Juicer finds WebP files
Browser caches
Chrome, Firefox, Safari and Edge all cache WebP images as part of normal browsing. When a website serves images in WebP format, the browser stores the raw WebP data in its cache. File Juicer can extract those images from the Chrome cache or Safari cache folders.
Android APK files
Android apps (.apk files) use WebP extensively for user interface graphics and artwork. APK files are ZIP archives, so File Juicer can open them and extract the WebP images stored inside.
Web archives and downloaded content
Safari web archives (.webarchive) and MHTML files saved from browsers can contain WebP images embedded alongside the HTML. File Juicer can extract them from those files.
Any file containing embedded WebP data
File Juicer identifies WebP files by their file signature (the RIFF/WEBP header at the start of each image) and can carve them out of any binary file that contains them, regardless of the outer container format.
WebP and animation
Animated WebP files work similarly to animated GIF but with much better compression. File Juicer extracts animated WebP files as complete files, preserving all frames.
