PDF-Images is a tool for Mac OS X that extracts images from PDF files. It is free, as in "there are no watermarks and no other limits whatsoever". PDF-Images is based on pdfimages, a Linux package by The Poppler Developers. Many credits to them!
- Extracts jpg, png, pbm, ppm images from PDF files
- Absolutely free of charge
- Mac OS X 10.8 or later required
Does what is says. Downside: does ONLY what is says. No options. E.g. if images from multiple pdfs are extracted they all receive the same file name (even though in different folders, each named after the pdf). Would be great if the images could be renamed based on the original pdf, including page numbers etc.). Support not tested.
Works almost as described. On my Mac I just dragged the app into Applications and ran it, using right click 'Open' to permit an unsigned app. Files came out where expected. Originally gave a 5, but had to reduce my stars. For some images, rather than an image file I get two files, e.g. image-029.ccitt and image-029.params. Not documented. Looked at the code but could find no occurrence of 'ccitt' or 'params'. I assume these are coming from one of the external components he is pulling in. I did find a sleazy workaround. It appears that one of the filters applied to the images within the pdf is missing or not able to be converted to jpg. In the original pdf I replaced occurrences of Filter/CCITTFaxDecode with Filter/FlateDecode and it seems to work. My documents are pdfs of scans of old typed documents.
Easy, simple to use and quickly+properly doing the job.
