First, you must know which version of Minecraft you are using. Although the differences between Minecraft Java & Bedrock are subtle, they can have a significant impact on how skins are changed in each one. Although the new unified Minecraft launcher makes it much easier to change skins in Minecraft Java, things can be a bit more complicated for Minecraft Bedrock skins, especially if your computer is not connected.

The Minecraft Bedrock edition handles skins in a different way than the Java edition. It's possible to import PNG files from the internet on PC, but you also have access to a powerful character editor.
The Bedrock Edition's character maker is only available for mobile and console users. It's more flexible than the one you can get by uploading a skin file, and allows you to customize individual elements of your avatar. Many of the more advanced options are only available if you purchase them or unlock them via achievements.
