There are moments in life when your phone's camera is crucial: your child's first steps, or their graduation from high school, for instance.

But your phone is likely full of stuff, and you could end up facing this obnoxious message:

There are few things as frustrating in our convenience-filled world as repeatedly running into your phone's storage limit. It means an action as simple as taking a photo is delayed while you free up space ... often by deleting old photos.

For most people hitting that storage limit, there's one culprit: photos. 

They take up a lot of space, and you take a lot of them — you might even be taking "HDR" photos (which are even larger files than standard photos). So, what do you do? You have two main options:

  1. Buy a phone with more internal storage, which costs more money.
  2. Regularly offload photos and delete them from your phone, which costs your time.

But there's a third, totally free, amazingly simple option: Google Photos. Here's everything you should know about Google's secret-best service.

If you have a Google account — Gmail, for instance — you already have Google Photos.

Select the menu icon from the upper left corner, then select Settings. The top option in Settings is the Back up & Sync option.

It's true, and it's incredibly simple:

-Navigate to photos.google.com (while signed in to your Gmail account).

-Start using Google Photos!

If, for some reason, you don't already have a Google account, you'll need one to use Google Photos. Signing up is free and easy.

But let's not kid ourselves — you probably have a Google account already, right? Almost certainly.


But you're here to free up space on your phone, right? For that you're going to need the Google Photos app — it's available for free on both the iTunes App Store and Google Play:

The app is really where the best Google Photos stuff is. I'll explain why momentarily, but first and foremost you need download links — here they are:

-iTunes App store

-Google Play store


Now that you've got the app installed, what's so good about it? While there are many answers to that question, prime among them is Google Photos' "Back up & Sync" function.

Despite logic dictating that you should click the "Free up space" option in the main menu, the first place you should navigate is the "Back up & Sync" menu in Settings. 

This is the main reason that Google Photos is so great: It takes your entire photo library — every photo you've ever taken on your phone, as well as screenshots and photos taken within Instagram and whatever else — and uploads it to the internet.

The photos remain private, hidden behind your Google account information, but now you can access them anywhere. On your laptop? Yep. On a new phone? Yep. On your tablet? Yep, there too. 

This unto itself is pretty incredible — but what's even more incredible is what this means for the concept of storing photos on your phone. Specifically: You can straight up delete your entire photo library, thus freeing up a tremendous amount of your phone's free space.


Having uploaded your phone's entire photo library to your Google account, you can safely delete that library from local storage.

Of my phone's 32 GB, I'm using around one-third of the storage. Notably, under 100 MB of that storage is being used by images. That's specifically because of Google Photos — every time I connect to wifi, my phone automatically starts uploading photos I've taken to Google Photos.

After it's done, it automatically deletes the original on my phone.  Sounds risky, right? What if it deletes a photo without fully uploading it? Good news: I've never had that happen. If anything, I'm consistently impressed with how seamlessly this whole process works.


Google Photos is remarkably flexible and customisable — you can bend it to your needs quite easily.

I was at Prospect Park in Brooklyn, in midtown Manhattan (near Business Insider HQ), and at the Park Slope Armory YMCA (my gym) in April 2016, apparently.

Perhaps you'd like Google Photos to group photos together featuring the same person/people? Google Photos can do that.

Or maybe you'd like to exclusively back up photos while you're connected to wifi? Google Photos is also happy to do that (you can also back up using cellular data if you'd prefer).  Perhaps you'd like to immediately identify any photos that have already been backed up, and then delete them? Just tap the "Free up device storage" button and you're all set.

Google Photos is a ridiculously customisable application. And that's especially important as we're talking about an application that manages and categorises every photo you take — one or two big mistakes could mean huge problems. In the past few years I've spent using Google Photos regularly, I've never encountered any major problems. I can't even think of any small-scale problems.

It's my actual favourite Google service, and I say that as a guy who depends on Google for the vast majority of my professional life.


Aside from the immediate benefit of offloading the photo library from your phone, there are other major benefits to using Google Photos. Like categorisation:

Because Google Photos uses geolocation and face recognition, it automatically puts together genuinely useful photo albums, collages, and movies. For instance, I went to Peru last month on vacation. While I was in Peru, I took a lot of photos (surprise!).

Before I could put together a photo album, Google Photos had already done so — every photo I took while in Peru, it automatically stitched together into a chronological album. That's rad! 


Going a level deeper, Google Photos automatically categorises your entire photo library for easy search. Wondering what you did in April 2016? Google Photos knows.

Google Photos allows you to label each common face it discovers, thus the "Wifey" moniker here.

Rather than just look through your photo library as a chronological list, Google Photos enables you to pinpoint a specific month and year for perusal.  That's nice, no doubt, but what's amazing about it is how that categorisation is used as the framework for all exploration of your photo library.

It smartly operates as the foundation for everything.


But what's even more impressive is how search works. What if I only want to see photos from the portion of my Peru trip that was spent in Cusco? Can do!

That's really rad as well. Maybe you want to see all the photos you've ever taken while visiting your in-laws in the Pennsylvania suburbs? That's totally doable. 


And search gets even more intense in Google Photos: How about searching by faces?

If you have a Google Pixel phone, you get unlimited uploads of full resolution photos and video. A nice perk!

I'm married, have no kids, and travel as much as humanly possible. Priorities! As such, I have a ridiculously large number of photos of my beautiful wife. Google Photos is keenly aware of this, and it recognises her in photos.

I can even search by her face to see the many instances of her appearing in my photos. 


There are a wide variety of search options in Google Photos, including "type," location, and by face.

Best of all, this is entirely free — you can upload an unlimited number of photos (they're slightly compressed, but still very high quality).

If you really want to upload full resolution photo backups, you can — but after a certain amount of storage, Google wants money. That said, the "high quality" option is beyond adequate. 


Perhaps you're uncomfortable with uploading all your personal photos to your Google account? Make sure you have two-factor authentication switched on!

First and foremost, if you're taking a lot of photos you'd rather keep private, it's totally possible that Google Photos isn't for you. Even with perfect security, there's needless risk involved.

That said, for the rest of us, two-factor authentication is more than enough back up. Remember when Apple's iCloud was hacked a few years ago, and various images of naked celebrities leaked to the internet? Apple's immediate response was to add two-factor authentication

Moreover, you should have two-factor authentication turned on anyway, so here's an excuse to do that. Google's got instructions for how to do it right here.
