NVA is a relatively recent file format used mostly for storing e-books which contain a lot of detailed images and graphics. The format is associated with the NVA Reader and is similar to PDF, but offers some optimized graphic features, making digital books look very similar to their printed version. The NVA Reader can function on most types of platforms, including Windows and Mac, as well as on operating systems used on several brands of smartphones and tablets (iPhones, Google Nexus, Samsung Galaxy etc.)
SGI (Silicon Graphics Image) is a raster image format associated with Silicon Graphics workstations. It is a bitmap file that can store black-and-white, gray-scale and color images, and may also contain color maps and alpha channels. SGI files are sometimes referred to as RGBs and can either use no image compression or RLE compression. Alternative extensions for the SGI format are BW, RGB and RGBA.
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 NVAs. 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 .nva files you intend to convert into .sgi 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 NVAs 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 .sgi files. You can also spend a few more moments to apply additional editing to the images prepared for conversion.
Then pick the SGI 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
