Files with the IMG extension are disc images used in Mac OS. After generating the image, the structure of data is not changed, therefore they can be used to store data as an exact copy, so that they can be mounted in a virtual drive and read as an original disc.
After converting the file to the new format, you will be able to use other programs to support it. Keep in mind, however, that the IMG file after converting to PBM may differ slightly from the original. The most important information should be kept, but if you want the file after conversion from IMG to PBM to be the same, you have to do this carefully and choose the proper application from the list below.
There is no guarantee, of course, that the conversion will come up to all your expectations, but it will certainly help you. If, after all, the effect of converting IMG to PBM does not meet your expectations, you can simply try to find on the Internet a different version of your file in IMG format, properly converted to a PBM file by someone else. If this fails, use the information provided in the further part of the website.
If after converting the file IMG the desired result was not achieved, you can try to change the format of IMG file to other than PBM. On our website you will find more information on the following conversion options
Unfortunately, if after performing the two previously described steps (trying to find your IMG file converted by someone else, and the attempt to convert it to PBM on your own) you still have a problem with your file, then there are only a few solutions left. You can once again try to find and install an application that can open the IMG file in its original format (without conversion to PBM file). Such a solution will be difficult to implement, but it certainly will give the best result.
