What is a .QOI file?

A .QOI file is a type of picture file that uses the Quite OK Image Format. This means that the picture inside the file is compressed in a way that doesn't lose any quality (this is called "lossless" compression). The pictures can have colors in a format called 24-bit RGB, which is a way to mix red, green, and blue light to make lots of colors, or 32-bit RGBA, which is the same but also includes transparency (the "A" stands for alpha, which controls the transparency).

These .QOI files are about the same size as .PNG files, which are another type of picture file you might have seen. However, .QOI files have an advantage because they can be made (encoded) or opened (decoded) faster than .PNG files. This can be really useful if you're working with a lot of images and need to save time.

To open a .QOI file, you can use several different programs. Some of these programs include: - ImageMagick: This is a software suite that can create, edit, compose, or convert bitmap images. It can read and write images in a variety of formats (over 200) including QOI. - XnViewMP: This is a versatile photo viewer, browser, and converter that supports a lot of image formats, including QOI. It's useful for viewing and managing your image files. - IrfanView: This is a compact and fast photo editing program that supports a wide range of image formats, including QOI. It's designed to be simple for beginners but powerful enough for professionals.

These programs can help you open and view the images saved in .QOI files, and sometimes even let you convert them into other formats if you need to.
