Over a period of time your phone definitely takes tons of photos and if you’re using Google Photos to backup your photos then I’m sure the storage might have been used to some GBs. Google Drive allows you to store max 15 GB of data (Drive, Gmail & Google Photos). For high-quality photos, Google gives you unlimited storage. But if the images are stored in original size, the upload quota is limited.
So if your photos have been accumulated in your drive account in original size and the storage is about to bid you bye bye, well here’s a way-out to free up Google Photos storage from Google Drive.
FREEING UP GOOGLE PHOTOS STORAGE
You can download all of your Google Photos to your local machine using Google Takeout.
Visit Google Takeout page and select the app Google Photos and click the “next” button to grab all the photos from your Google Account.
After you’ve downloaded all your photos (make sure you have all of them), delete the online copy of photos from Google Photos app.
Now within Google Photos app, visit settings > backup and select the quality of photos to “high quality”. Selecting high quality gives you unlimited storage quota for backing up your photos in Google Photos.
