To always keep your render results with the highest possible quality,

always save your projects as PNG files first. If you need a smaller

version, you can convert the PNG to a JPG file later. Depending on your

project, you might want to use EXR for post-processing. But, in most

cases, a PNG is the best choice.

The reason to keep your renders as PNG files is because it uses a type

of compression for images called lossless. With this method, you get

larger file sizes but with no data loss from your renders. It is a

compression similar to what ZIP containers do with text files.

On the other hand, a JPG file uses a compression method called lossy,

which excludes some information to reduce file size. Every time you

save a JPG file, the algorithm will exclude data from your image to

reduce file size.

For that reason, try to save all renders as PNG files first and then

convert them to JPG later if you need a smaller file.

6.4.1 Image settings for rendering

An important setting for any render in Blender is the resolution of your

images, which is also a factor that can determine how long it will take for
