The new Google Photos storage is lossy unless you pay for it. That doesn't rule out using the images in a different way though.

I thought it was only lossy if the originals you uploaded were >16MP. I tested uploading some <16MP images and redownloading them, and they didn't seem to have undergone any lossy conversion.

Did you compare a hash of the file, or did they just look the same?
