We’ve all been there you go to take a quick snap or download a new app, only to be hit with the dreaded “Storage Almost Full” warning. And for many of us, the last thing we want to do is delete our precious photos and videos to make room.


The good news? You don’t have to. There are several smart, simple ways to free up space on your phone without losing a single photo. Whether you’re using an iPhone or Android device, this guide will walk you through practical steps to clear clutter, back up files, and keep your memories safe while reclaiming valuable storage.

1. Use Cloud Storage to Back Up and Optimise Photos

One of the easiest and most effective ways to free up space is to use cloud storage services that automatically back up your photos and videos then remove the full sized versions from your phone while keeping smaller thumbnails locally.


Recommended options:

  • Google Photos (Android & iOS): Offers 15GB of free storage (shared across Google services), with paid options for more.

  • Apple iCloud Photos (iPhone): Comes with 5GB free; paid plans start at 50GB.

  • Amazon Photos (Free with Prime): Unlimited full resolution photo storage for Prime members.

  • Microsoft OneDrive: 5GB free, with seamless integration into Windows and Office.


How it works:

  • Once backed up, you can safely delete the original high resolution files from your phone.

  • These apps still show preview images in your gallery tap to re download when needed.


Tip: Make sure backups are complete before deleting local files. Most apps have an “Optimise Storage” or “Free Up Space” button in settings use that instead of manually deleting anything.


2. Clear App Cache and Temporary Files

Many apps build up a surprising amount of temporary data in the background things like cached images, videos, or files that can safely be removed without affecting functionality.


For Android:

  • Go to Settings > Storage > Apps

  • Tap on large apps like Instagram, Chrome, or Spotify

  • Choose Clear Cache (don’t select "Clear Data" unless you want to reset the app)


For iPhone:

  • Go to Settings > General > iPhone Storage

  • Some apps (like Safari) let you clear cache directly

  • Others, like social media apps, may require deleting and reinstalling the app to clear space


Extra tip: Messaging apps like WhatsApp and Telegram can store loads of media. Review and delete unneeded videos and voice notes from within the app settings.


3. Offload Unused Apps (Without Losing Data)

You may not need to delete apps entirely. Both iPhones and some Android phones allow you to “offload” or “archive” unused apps. This removes the app itself but keeps its data intact, so you can reinstall it later without losing progress.


On iPhone:

  • Go to Settings > General > iPhone Storage

  • Tap on unused apps and select Offload App

  • Or turn on Offload Unused Apps to automate the process


On Android (depending on device):

  • Use Files by Google to identify and archive rarely used apps

  • Or check your App settings for “Remove rarely used apps” options


Why it works: You’ll free up space without losing login details, preferences, or saved content.


4. Use a File Cleaner App to Spot Hidden Clutter

Sometimes, the biggest storage hogs are files you don’t even realise are there duplicate files, downloads you forgot about, or leftover data from uninstalled apps.


Try these tools:

  • Files by Google (Android): Smart, safe, and free. It identifies large files, duplicates, and unused apps.

  • iPhone Storage Recommendations (Settings > General > iPhone Storage): Offers suggestions for clearing videos, message attachments, and more.

  • CCleaner (Android): Another option for cleaning app caches, downloads, and logs.


Tip: Don’t forget your Downloads folder it often holds PDFs, installers, or memes you saved months ago and no longer need.


5. Move Files to an External Drive or Computer

If you’ve backed up your photos and videos to the cloud but still want a local copy, moving them to a computer or external drive is a great option especially for large videos or RAW photo files.


Options include:

  • USB-C or Lightning flash drives (e.g. SanDisk iXpand for iPhone or Samsung Duo Plus for Android)

  • Wireless external drives (like WD My Passport Wireless or iXpand Wireless Charger)

  • Manually transfer to PC or Mac via USB cable or AirDrop (for iOS)


How to keep things organised: Create folders by month or event, then delete the originals from your phone once safely stored.


6. Tidy Up Your Messages and Attachments

Text messages may seem lightweight, but over time, attachments like photos, GIFs, and voice notes can build up fast especially in group chats.


On iPhone:

  • Go to Settings > Messages > Keep Messages and set it to 30 days or 1 year

  • In a message thread, tap the name > Info > review and delete media files


On Android:

  • In Google Messages, go to Storage settings and manage large files

  • Or install Messages by Samsung (if available) which includes clean-up tools


Quick win: Delete old one time password texts, expired links, or promo messages you don’t need anymore.


7. Disable Auto-Download in Messaging Apps

WhatsApp, Telegram, Signal and others can be set to automatically download media sent in chats. This fills up your phone quickly if you're in busy group chats.


How to stop it:

  • In WhatsApp: Go to Settings > Storage and Data > Media Auto-Download and turn it off for Wi-Fi and mobile data

  • In Telegram: Settings > Data and Storage > Automatic Media Download

  • You can still tap to download manually when needed


Bonus tip: Periodically go into your messaging apps and clear out large files in the media gallery.


Final Thoughts


You don’t need to choose between keeping your favourite memories and having enough space for new ones. By using cloud storage, clearing cached data, offloading apps, and organising your files, you can free up valuable space without deleting a single photo.


Here’s a quick recap of what to do:

  1. Back up and optimise your photos using cloud storage

  2. Clear app caches and temporary files

  3. Offload unused apps (but keep your data)

  4. Use file cleaner apps to remove clutter

  5. Move files to external storage or a computer

  6. Tidy up messages and delete bulky attachments

  7. Stop messaging apps from auto-downloading media


Phones these days are mini computers in our pockets and just like any computer, they need a good spring clean now and then. Set aside 15 minutes a month for digital housekeeping, and you’ll never see the “Storage Full” warning again.
