The BW format represents the black-and-white version of SGI (Silicon Graphics Image), a raster format created using Silicon Graphics workstation. Similar formats include RGB and RGBA. SGI and its related file extensions were first developed by Paul Haeberli and wereinitially released in mid-1990s. They are currently considered obsolete and difficult to open with regular image viewers.
The APNG format is also known as "animated PNG" and is made up of a series of PNG files of the same size that are connected as an animation. APNG files are similar in function with GIFs, but they support better quality images and transparency.
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 BWs. 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 .bw files you intend to convert into .apng 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 BWs 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 .apng files. You can also spend a few more moments to apply additional editing to the images prepared for conversion.
Then pick the APNG 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
