If your iPhone or iPad is full, there are several things you can do to claw back storage space. In this guide, we run through several options and methods available to free up storage on iOS devices. Keep reading to learn what they are.


Every iPhone and iPad comes with a set storage capacity ranging from 16 GB to 512 GB for iPhone, and 16 GB to 1TB for iPad. While it's always a good idea to buy a model with the biggest storage you can afford, after a while even the highest storage devices can fill up, and it often happens when you least expect it.

From the music you buy and the apps you download, to the photos you take and the messages you receive, all of that content has to live somewhere on your device. And when your iPhone or iPad storage is full, it's not like you can increase it. What you can do, however, is free up your existing storage. Here's how.

Basic Storage-Saving Tips

Apple is aware that many people struggle to manage storage on their devices, which is why it has introduced more and more tools with successive versions of iOS to help users keep on top of the kinds of apps and media that often eat up precious megabytes.

Launch the Settings app and select General -> iPhone/iPad Storage, and the amount of storage space you've used is shown in the color-coded bar at the top. Below it, you may see a list of recommendations for optimizing storage, by reviewing and deleting large attachments, for example.


These recommendations are followed by a list of installed apps and the amount of storage each one uses. The list also tells you when you last used each app, allowing you to easily find and delete the apps that you haven't used for a while or not at all.


When you delete an app, its icon, app data, and any user-generated data is removed. That's fine if you don't intend to use the app again, however Apple also lets you offload apps, which frees up storage space, but leaves the app's icon and user data in place. If an app you use a lot is taking up a lot of space, it's worth checking if you can clear any cache associated with it.


Another option that Apple added to iOS not so long ago is the ability to prevent your iPhone or iPad from from automatically installing software updates. It used to be the case that new software updates were downloaded automatically in the background and then installed through an Automatic Updates feature. However, in iOS 13.6 and later, the Settings app includes toggles that let you choose whether updates are automatically downloaded.


Reclaim Space Taken Up By Photos

The photos that you keep on your iPhone or iPad naturally take up storage space on your device, which can fill up quickly depending on the available storage capacity and how much content you have.

If you see a message that your device's storage is full, it's worth checking out a system option called Optimize Storage, which is designed to work with iCloud Photos. This feature replaces full-resolution photos on your iOS device with smaller, device-sized versions that take up a lot less storage space, while the full-resolution images remain off-device in iCloud.


Another way of pruning your photo library is checking for redundant shots taken in Burst Mode. Burst Mode refers to when the camera on your iOS device captures a series of photos in rapid succession, at a rate of ten frames per second.

It's a great way to shoot an action scene or an unexpected event, since you're always more likely to end up with the picture you were aiming for. But it also generates a lot of unwanted images, so it's good practice to pick out the best image for safe keeping, and delete the rest to save on storage space.


If you have an older iPhone, you can also save space when shooting in HDR. On iPhone X and earlier models, when the camera takes an automatic HDR photo, it can also optionally keep the standard shot in your Photo library, which is useful for comparison or for when the HDR picture doesn't come out as expected. However, if you want, you can disable this function and thereby save yourself some storage space.

In some cases, you can find your photo library getting bigger even when you haven't been taking pictures on your device. For example, the media that people share with you over WhatsApp may be automatically saved to your iPhone's Camera Roll. Fortunately, you can easily prevent this default behavior by disabling Save to Camera Roll in WhatsApp's in-app settings.


Of course, if your photo library feels like it's ballooned out of control, one solution is to start afresh and delete all the photos on your iPhone. Just make sure you've already backed any up that you want to keep, and be aware that deleting your photos with iCloud Photo Library enabled will delete your photos from ALL of your devices.

Reclaim Space Taken Up By Videos

Some of the above photo tips apply to videos stored in your device's photo library. However, there are other ways to prevent video content from eating up storage space. For example, you can customize the resolution and frame rate of recorded video to reduce the file size in Settings -> Camera -> Record Video.


Elsewhere, if you regularly download Apple Fitness+ videos to your ‌iPhone‌ or ‌iPad‌, check the recommendations in Settings -> General -> iPhone Storage and you should see them listed under Review Downloaded Videos, where you'll be able to delete them individually or in bulk.


If you have an Apple TV+ subscription, or you've rented or purchased movies via iTunes, you can download videos using Apple's TV app to watch them offline. However, if you're looking to save space, make sure that you've selected Fast Downloads (lower quality, uses less storage) in Settings -> TV -> Cellular Data – it means lower quality videos, but they use less storage.


Reclaim Space Taken Up By Other Apps and Media

WhatsApp features a built-in media management tool that can help you identify, select, and bulk delete GIFs, photos, and videos that may be filling up your phone.


The tool groups together large files and media that has been forwarded many times, sorting files by size in descending order, and provides a way to preview files before deleting them. You can also see a preview of media before selecting one or multiple files to delete. To access the storage management tool, launch the app and go to Settings -> Storage and Data -> Manage Storage.

If you're an Apple Music subscriber, you can download songs, playlists, and albums from the ‌Apple Music‌ catalog to your iPhone or iPad for offline listening, but this can gradually eat up your device's storage space over time.

Fortunately the Music app includes a handy feature that can spring into action whenever your device's storage space runs low, and automatically offload songs you haven't played for a while in order to make space for newer ones.


Check Settings -> Music -> Optimize Storage, and make sure the Optimize Storage switch is enabled. From here, you can also choose a minimum storage amount that you want to keep for music before downloaded songs start being removed from your device. You can also monitor storage space by turning off automatic downloads in Settings -> Music and downloading new songs manually when needed.

Apple Music can users also remove individual tracks in the Music app. Simply press and hold an item, select Remove... from the pop-up menu, and then tap Remove Download when prompted.

There are several ways to trim fat from the Messages app. For example, iOS can be automated to discard old messages that have been on your device for longer than a specific period of time.


In addition, if you tap the contact bubble(s) and then the info (i) button at the top of a Messages conversation, you can also see every file that has been sent to you in the chat thread in one easily accessible location, where you can remove them all in one fell swoop.


Messages in iCloud, as the name suggests, stores your iMessages in Apple's cloud servers rather than on each of your individual devices. One of the benefits is that your messages, photos, and other message attachments are stored in ‌iCloud‌, which frees up space on your devices. You can enable it in the Settings app by tapping your Apple ID banner and selecting iCloud -> Messages.


Other Apple apps that are worth checking include the Books app and the Voice Memo app. If you listen to a lot of audiobooks, try nixing your back catalog, and review any old Voice Memo recordings to see if you need them any more.

Wrapping Up

We've run through the main storage-saving tips for iPhone and iPad, but depending on your use case, there may be other ways that you can free up space on your device. For instance, if you do a lot of on-device file management in the Files app, consider compressing large files and folders by selecting Compress from the contextual pop-up menu.


If you're still short on space and you've exhausted all the above options, it may be worthwhile resorting to the "nuke" option – a clean install – by erasing your device and starting again. If that doesn't help, it could be time to upgrade your device.

Dang! Twitter app is using 2.06GB documents and data on my iPhone. This directly conflicts with what is shown in the twitter settings - Media = 76MB and Web = 13.2MB

I'v never needed more than 32GB of storage, never got close to running out, I'm a developer been using Mac and iOS for years since the 90s and never once had a storage issue so guess it's down to the average consumer going wild and not after a month or 2 weeks go threw and delete unwanted unused data and any photos not viewed or used backed up on external storage and online storage

Some people like to keep all of their photos/videos/music on their device without having to rely on cloud storage.

Biggest thing taking up space for me are photos and video.
I ended up with the 512gb 12 Pro Max because my 256gb 7 Plus was nearly full.

the biggest space saver for me was turning on HEIF/HEVC for photos and videos.
I’ve taken so many photos and videos since I got my 12 Pro and I’ve barely used any additional space. Still well below 256gb of use.

I don’t delete photos and videos because yes I do go back and look at them.

I had to wipe my 32GB iPad a couple weeks ago. The problem is that Apple tells you that you can save 1GB from deleting large attachments, but then you go into the storage management pane and there are definitely not even close to 1GB worth of files attached. Deleting is slow, because while you can 'edit', it doesn't provide any sort of 'select all' widget.

But the overwhelmingly worst thing is the 'other' category, which just cannot be removed. It doesn't belong to any particular app, it just accrues over time. If you have a lot of app churn, which my iPad did, it eventually gets to the point where it takes up the majority of the space and you're screwed.

Of course, doing a full wipe of the iPad has its own problems, like if you've bought anything off of the messages app store area—those things are gone and you can't get them back. You could of course restore from backup, but the thing I was trying to avoid was all the cruft that got me in trouble in the first place. Apple's storage management options are woefully inadequate, and honestly, losing functioning stickers/apps with no recourse is just bad practice. That particular corner of the app store is such an afterthought.

I gave up on trying to make space on my 256 GB iPhone 7. It won't connect to Image Capture on any Mac I have tried. It's literally full (256 of 256 GB used) which is why I think it has so many freaky bugs and is unusably slow. I have deleted everything I can but the videos/photos, which I refuse to delete. But it's become a paper weight now. I ended up buying a really cheap Android phone with a micro-sd card slot that makes it really easy to store all my photos/videos and get them out (plus I started using Google Photos, which unfortunately lose its unlimited backup status soon).

I've tried so much troubleshooting with different Lightning cables, different versions of Mac OS, etc. At one point when this first started, I had found a temporary solution. And there are times it would work. Sometimes some photos would show up and I would import those really quickly and then delete them from the phone, but it was so few that it still is at 256 of 256 GB used.

It's the same problem with Preview and Photos on the Mac which use the same importing software as Image Capture.

I've tried AirDropping, but as I said everything on this phone is so slow and buggy now it doesn't work. Just opening the phone app it will crash multiple times before opening.
