The quick and simple way to handle your files is to get a quality piece of software, such as reaConverter. This software is extremely efficient in managing a wide range of batch conversions. As you will soon realize, reaConverter will help you avoid spending countless hours trying to figure out how to convert multiple SFF files as once.
Start reaConverter and load all the .sff files you intend to convert into .fax 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 SFFs 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 .fax files. You can also spend a few more moments to apply additional editing to the images prepared for conversion.
Then pick the FAX 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
