Transparent images PNG files in Keynote

I tried to drag a PNG image file into my KeyNote presentation but the white background still there and not transparent. I thought PNG file suppose to be transparent in Keynote. Is there anyway to make the image transparent without the white background??

I am running Keynote 7.31 under High Sierra.

Thanks.

MacBook Pro, iOS 10.3.1, OS is Sierra 10.12.4

Keynote supported files Hi, I am very not up to date with technology so please make your answer very beginner friendly (dumb it down for a dummy). I am trying to upload a download onto Keynote and it's not supporting most files it looks like. Everything is pretty much greyed out. Perhaps I need to update the app? For context, I am trying to upload a transparent background file from Canva. It is a PNG and Transparency is marked.

Make keynote background transparent once exported I am trying to make the background of my keynote slide transparent so that I can overlay it onto a video in iMovie, but when I export by: Selecting no fill for the background (turns it black) Selecting export> movie> custom resolution> apple ProRes 422 (which is what is suggested on another post here) It just gives me a small movie file that is a completely black screen. Also when I try importing it in to iMovie, it stays a black screen. When I try the same as above, but select apple ProRes 4444 instead, it gives me an option to select a box that says 'export with transparent backgrounds' which I select, but the same thing as before happens; completely black screen. Am I doing something wrong or am I missing a step? Thanks in advance :)

Keynote - Export to Movie, transparent background checkbox not an option I am trying to export a movie on keynote with a transparent background and the option just isn't even there. How do I change this? Is this an update issue? Or an OS issue? What is going on? See photo below. Only gives me options for resolution. No mention of ProRes 4444 or anything. Help! (And yes, on the slide, I had selected no fill for the background).

Images must already have a transparency channel attached to the image file created in an image editing application for transparency to work.

If the image has a single colour background (e.g. white) it can be removed in Keynote using the instant Alph tool: Format > Image > Instant Alpha

Click and drag the cursor over the background to remove.
