So if you have a png with transparency you want to save after that, you have to remember to specifically change the option back to "automatic" or to the specific "8bpc rgba". First, open up the image in Gimp by going to File -> Open as Layers.: Click on the background of the image (the area which you want to make transparent): Go to Layer -> Transparency -> Add Alpha Channel: Press the Delete keyboard button: Go to File -> Export As. First, you need to add BMP image files for processing: drag & drop your BMP image files or click inside the white area to choose files. However, be careful when using this, because the application will remember this choice for other pngs saved within the same run of the program. In newer Gimp versions, the save options popup for png format has a list of pixel formats, allowing you to select "8bpc RGB" to save without alpha channel. When working with Gimp xcf projects I generally prefer the second method, since it means there is no risk of accidentally saving your flattened project and losing all your layers. The best solution for this seems to be to either use the "Flatten Image" function before exporting (available in the right-click menu of the Layers dialog, or just in the menus under Image), or to just export the image, then open the exported file (it'll be easily accessible in the "Open Recent" menu), and then removing the now-single layer's alpha channel and using the function to export to the same filename again. You can use it by pressing Shift + O or going to Tools -> Selection Tools -> By Color. Gimp doesn't seem to detect that final lack of transparency, though, so when I export to png, it always ends up containing an alpha channel. To make the background transparent we will use the Select By Color Tool. You can save the image now, but it will have jagged edges.This is actually an annoying problem in Gimp I often find myself having projects with multiple layers, but with a bottom layer without transparency, so having an alpha channel on the final exported image is a complete waste of space on that. Now, press the Delete key on the keyboard to delete the background.

The trouble is if you simply delete them with the eraser tool, youll end up with a great big splodge of the background colour. But, we can fix that by using a free and feature-rich image editing software called GIMP. Since this image is not a vector or a transparent PNG, it does not have a transparent background. The ‘white box’ is visible and there’s really no way to make it disappear from within PowerPoint. This is probably not the result you were looking for.
