The MAC extension stands for bitmap images associated with the MacPaint program developed by Apple MacIntosh. MAC images only support a monochrome (black and white) color rendering, are not scalable and have a modest resolution of 75 dpi. However, they are quick to download and decompress. MAC files can also be found under the PNTG extension on Mac computers and they are frequently used for clip art or monochrome graphics.
FLIF (Free Lossless Image Format) is a royalty-free format launched at the end of 2015 as "work in progress" with the aim of offering a better alternative for storing lossless images than the existing PNG, WebP, BPG, JPEG2000 and JPEG XR. FLIF provides similar image quality as the other extensions, but in a file size than can be up to 74% smaller. The new format uses a form of the Adam7 algorithm for compressing images, offering progressive interlacing that allows users to obtain a reasonable encoding of an image even from a partial download.
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 MACs. But at the same time, it will allow you to apply a wide range of editing options.
Start reaConverter and load all the .mac files you intend to convert into .flif 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 MACs 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 .flif files. You can also spend a few more moments to apply additional editing to the images prepared for conversion.
Then pick the FLIF 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
