Or perhaps I don't see what you see.

I take a photo, the format is jpeg. It backs up to Google photo, the Google photo app on Android renders the photo just fine.

I then convert that photo (via a local converter) to AVIF, Google backs it up, I can see the file in Google Photo on Android but it doesn't render the image. That being full size or thumbnail, all I get is a grayed square. So I concluded the app doesn't support avif rasterizing.

I then gave up on the automation that converted all my jpeg into avif, which in turn would have saved hundred of gigabytes given I have 10y worth of photos.

The experiment was done about 3 months ago, as of 2025 Google Photo on Android, latest version, would not render my AVIF photos.
