If you need to merge two PNG files with a transparent background into one in order to upload as your Outro background image on Promo in one piece as a logo, please follow instructions below:
Firstly, you need an image editor to merge your files. You can use free https://inkscape.org software for that purpose. Follow the link, go to Download section there and pick your operating system.
https://inkscape.org/en/download/mac-os/ - for Mac
https://inkscape.org/en/release/0.92.3/windows/ - Windows systems
Then, install the software on your PC/Mac and launch it.
You need to click on File > Open (Ctrl/⌘+O) and pick your first PNG image/logo
After that, it’s File > Import (Ctrl/⌘+I) to paste your second PNG file
Once it’s done, you can rearrange positioning of your images, scale them to make one/both smaller or bigger relative to each other by dragging the pointers.
When you are ready to save your file, click on Select all objects/nodes icon in the top left corner (Ctrl/⌘+A)
Then File > Export PNG image (Shift+Ctrl/⌘+E)
In the window that appeared, you can adjust image resolution, save location etc.
Click Export to save the actual file on your PC. If both of your original PNG files had a transparent background, it will remain so on your new, merged image. Now you can grab the file and Upload as Logo on Outro slide in Promo editor.
