GIMP is an advanced image editor and you can use it to add transparency to an image. The process is going to be a bit different if the image you start out with isn’t a PNG. In some cases, the process can also be a little tricky even if you have a PNG file. This is because of something called the ‘alpha channel’. This is where transparency is stored and if it’s absent, GIMP won’t be able to make the image transparent. The fix is simple. [ Ссылка ]
