ISM files are associated with Image System and they most likely contain a bitmap image that was created a long time ago. A similar image format associated with Image System is ISH, which contains high-resolution images, while ISM contains multicolor images. Opening both formats might pose difficulties when using a regular image viewer, so converting them to more accessible formats is probably the best solution for easier opening and transferring.
The BMP or Bitmap file format is a popular raster graphic format, compatible with a wide array of image processing software, both on PC and Mac computers. BMP files store grids of pixels and detailed information concerning color tones and shades, and are highly appreciated for their ability to provide increased quality images. However, due to the lack of any compression algorithm in storing pixel data, BMP images can often be very large in size and thus difficult to store or transfer.
The quick and simple way to handle your files is to get a quality piece of software, such as reaConverter. Although it is fast, this software is extremely efficient in managing a wide range of conversions. As you will soon realize, reaConverter will help you avoid spending countless hours trying to figure out how to convert ISMs. But at the same time, it will allow you to apply a wide range of editing options.
reaConverter is quick to download, install and launch, and you don't need to be an IT specialist in order to understand in a few minutes how it operates.
Start reaConverter and load all the .ism files you intend to convert into .bmp because, as opposed to most free online converters, reaConverter supports batch conversion. So you can save the time and energy you would lose with doing repetitive operations.
Select ISMs from a folder or by drag-and-dropping them directly into the reaConverter window.
Go to the Saving options tab and decide where you want to save new .bmp files. You can also spend a few more moments to apply additional editing to the images prepared for conversion.
Then pick the BMP as output format. To help you do this, a series of buttons is conveniently placed at the bottom of the reaConverter window, so you can simply press on the one you need or click Plus button to add new options.
Then simply press the Start button and your conversion will begin in no time!Try Free Trial Version
