File Juicer
File Juicer is a drag-and-drop can opener and data archaeologist. Its specialty is to find and extract images, video, audio or text from files which are hard to open in other ways.
It finds and extracts: JPEG, JP2, PNG, GIF, PDF, BMP, WMF, EMF, PICT, TIFF, Flash, ZIP, HTML, WAV, AVI, MOV, MP4, MPG, MP3, AIFF, AU, WMV, or text from files which contain data in those formats.
Lossless extraction… File Juicer does’t convert the images/sounds/videos it finds, but saves them unchanged in their original format if possible. See the manual for details.
