This tutorial explains how to create animated PNG from PNG and TGA images.

APNG Assembler is a free software to generate animated PNG file from still PNG and TGA images. You can add multiple supported images on its interface and quickly create APNG file which you can use wherever you want. For every single input image, you can also set the time delay that makes it more interesting. You can set time (in seconds) when the next image will appear after the current frame while playing your APNG image.

This process to generate APNG file is similar like creating animated GIF. Multiple images are packed (known as frames) to create a single animated file. Although, APNG file is not so popular as compared to GIF file. However, for any reason, if you want to create an APNG file, this software will be very useful.

Note: Make sure all input images are of the same size (height and width), otherwise it will show an error. Moreover, it checks the size of the first image and consider that size to be exactly same for the rest of the images. You have to resize all the images, before inserting them on its interface.
