You can use PS software to remove the white background. The steps are as follows:

1. First, I open a personally designed logo.

2. Find the background item in the layer and click the little eye next to it to hide the background layer.

3. Find the file menu bar and click Save As.

4. Find the save type. If you want to save the logo without a white background, you must choose to save it in png format. You must not save it in jpeg format, otherwise the saved image will still have a white background. .
