Edit all you want, because Google Photos will keep your originalsWell, on the Android app.
If you're prone to overfiltering, cropping and general meddling with your photos, you just keep right at it -- if you're using Google Photos on Android. The app has been updated to ensure it keeps the original shot irrespective of how many times you resize, shape and brighten it. Now, users can save their edits or save a new copy of the photo, but irrespective of which, the original will also stay filed away inside the Photos app. The new feature is inside version 1.17 -- and I'm telling you that now so that no-one goes crazy with the cropping before they're sure they've got the right update.
