How do I use alpha texture in Blender?
To use an image textures alpha channel in Blender we need to set up a material that combines a shader node like Principled BSDF with a transparency BSDF node. We mix the two shaders together with a mix shader and use the alpha channel from the image texture node as the factor input.
How do you make a texture transparent in Blender?
In Material Properties, under Settings, click the drop-down menu to the right of Blend Mode [6] and select an option, typically Alpha Clip, Alpha Blend or Alpha Hashed. Blender will finally display the transparent aspects of the material.

Can a JPEG file be used in Blender?
A JPEG for instance does not support alpha, while PNG files does. There are other file types that also support alpha, but PNG is the file type you are most likely to come across. There are also alternatives. For instance, we can use the built-in procedural textures in Blender to generate an alpha channel.
