The short answer
Why use Image Extractor?
File details explain why a photo prints badly, turns sideways, or reveals more than you meant. Checking the file first saves guesswork.
Many JPEGs from cameras and phones carry a small preview picture inside their EXIF data, the thumbnail a camera shows on its screen or a file browser shows in a grid. This tool reads that embedded JPEG and saves it as a separate file named after your photo, ending in -embedded-preview.jpg.
The preview is usually small, often 160 × 120 pixels, and it may not match the main picture if an app edited the photo later without updating the thumbnail. That mismatch is sometimes how people notice a photo was cropped or retouched.
Screenshots, PNGs, and photos saved from social media or chat apps rarely contain a preview, and the tool says so instead of giving you an empty file. It does not cut separate pictures out of a collage or a scan. For pictures inside a PDF, use Extract from PDF.
