How to open APT files

Did your computer fail to open an APT file? We explain what APT files are and recommend software that we know can open or convert your files.

What is an APT file?

We know of 3 different uses of the APT file type, one of them being Adaptive Prediction Tree Encoded Bitmap. Read the details below.

The APT file extension indicates to your device which app can open the file. However, different apps may use the same file extension for different types of data. So an APT opener may not be able to open all kinds of APT files. In this case, look through all formats to make sure you find the best suited APT viewer.

Adaptive Prediction Tree Encoded Bitmap

When an image needs compression to save space, one process used is APT. The files created in the process are called .apt files. APT stands for Adaptive Prediction Tree. There are two types of image compressions for .apt files: A lossless image is a compressed image with no data from the original image discarded, and a lossy image is a compressed image with data from the original image discarded. The image quality is the same as the original for lossless compression, where lossy compression sacrifices image quality for improved space savings.

John Robinson, a researcher who focuses on image processing and analysis, developed the APT compression method.
