Check out the new Google Photos app — which comes with unlimited storage for photos up to 16MP and videos up to 1080p HD resolution. Just choose ‘high quality’ when you upload them through the new Photos app or Photos desktop uploader if you’d like them stored for free.
Just like before, the images and videos you keep in Google Photos will appear in Google Drive automatically and any you upload or sync using Drive will always be the uncompressed, originals and will use your available storage.
