A TSK file stores a theme or skin image designed for a pocket PC or PDA (personal digital assistant). These types of gadgets were popular before smartphones became widely available, but have been on a steady decline since the early 2010s. TSK files are rather rare at the moment and probably difficult to open outside the operating system used by the gadget they were created for.
A CAL image file represents a monochrome bitmap image that uses the CALS raster image standard for storing graphics data. This standard was created in the 1980s by the US Department of Defence as a compressed interchangeable image format. CAL and CALS are extensions used for similar purposes.
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 TSKs. But at the same time, it will allow you to apply a wide range of editing options.
Start reaConverter and load all the .tsk files you intend to convert into .cal 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 TSKs 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 .cal files. You can also spend a few more moments to apply additional editing to the images prepared for conversion.
Then pick the CAL 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
