Extract Image Files From Apps & Documents Using deJPEG For Windows

deJPEG is a desktop application for Windows that lets you extract images from applications or documents, and save them as separate items. The tool mainly supports Microsoft Word files (DOC and DOCX) and EXE files, though it may (or may not) work with other files that generally have image resources embedded into them, as long as the images originally inserted into these files/documents by their developers or editors were in JPEG format. This means if the developer or the person composing the document used PNG or some other format for these images, deJPEG will not be able to extract them for you. The output files are stored as JPEG.  The application can prove extremely useful for those who need to use images found in a certain files or apps that can’t be easily found elsewhere, and they would rather not waste their time by individually taking a screenshot of each image and go through the hassle of cropping it properly. The tool can analyze and extract all images it finds in one go, making the process simple and streamlined.

The interface of the tool looks pretty bare bones, and doesn’t carry any complicated set of options that the end users might find confusing. Though this may also end up as a downside of the app, as some power users may find it a little too simple for their taste, having little flexibility and control over the types of images they would like to extract or where they want to put them. All you can do is click the ‘Analyze file’ button, select the source file, and let deJPEG do the rest. It automatically analyzes the chosen file and extracts the appropriate image files in the same location as the source item. It would have been nice to have an option to let users decide where the output files should be saved.


Moreover, the application doesn’t offer a way to specify some sort of renaming scheme regarding the output images (the output files are simply stored as image1, image2 and so on), nor does it let you specify if you want to exclude images smaller or larger than a specific size or dimensions, which would have been really handy. When the images are extracted, the tool displays the results at the bottom, letting you know about the number of images that were successfully pulled out from the source.

During testing, I threw in a handful of different files in to the app and got mixed results in return. Some extracted pictures were a bit distorted, while at times the app didn’t work at all. Another major nuisance is that the app doesn’t explicitly state the types of files it supports. For instance when you browse the source file, it simple displays ‘All Files’ in the file support list. On the bright side, however, it’s a portable application and you can use in on the move by storing it on a USB drive.

Overall, it’s a decent app that can extract a batch of images from documents and program files. Testing was carried out on Windows 8 Pro, 64-bit.
