Some PDF Image Extract
Some PDF Image Extract is a program that you can use to extract images from PDF documents.
In the plain and simple interface, you can import a file or directory by using the file browser (the "drag and drop" function is not supported but batch processing is).
In the queue you can check out the size, date and time of creation for each file, and if an owner or user password is required.
So, all you have to do is specify the output destination and format, in order to initiate the extraction process.
But you can also select the page range, set the tool to open the output directory after extraction, as well as choose the JPEG quality and toggle grayscale mode. Settings can be restored to default at any time.
The program quickly finishes a task while using a moderate amount of system resources. No errors have popped up during our tests and Some PDF Image Extract didn't freeze or crash. Plus, there is a brief online help file available.
But we have encountered a very irritating problem. Sometimes, Some PDF Image Extract does not extract images, although no failure message pops up (the output directory is empty) and this seems to happen randomly. It usually works after you select the "Reset all options" in the "File" menu (even if you didn't make any modifications).
The bottom line is that Some PDF Image Extract is a very good program for the simple operation of extracting graphics from PDF documents, but the aforementioned problem makes the software very unstable.
