Quick answer: before paying for more storage, check what is actually using it. Google’s help page says storage is shared across Gmail, Drive and Photos, and that Gmail Spam and Trash and Drive Trash still count until you permanently delete their contents (Google’s storage help page). Google and Apple both publish cleanup tools, and this guide puts them in an order you can follow, with an AI prompt for planning the cleanup without sharing any file contents.
Contents
What Counts Toward Your Storage
- A Google Account gets 15 GB shared across Gmail, Google Drive and Google Photos.
- Photos and videos backed up in Original quality count, as do Gmail messages and attachments and Drive files.
- Deleted Photos items stay in trash for 30 days before permanent removal, and after large deletions the total can take 48–72 hours to update (Google’s storage help page).
- Apple’s iCloud starts with 5 GB free. When it runs out, backups stop, new photos and videos stop uploading to iCloud Photos, iCloud Drive stops staying up to date, and iCloud email can’t send or receive (Apple Support).
A Cleanup Order That Makes Sense (Google)
The order below is my suggestion, built on how the storage rules work:
- Check the breakdown first. Google’s storage manager shows usage by service (Photos, Drive, Gmail, Trash), so you know which category to target (Google’s storage help page).
- Empty the trash and spam. Those items still count until permanently deleted (Google’s storage help page).
- Review duplicates and screenshots. Skim flagged batches before deleting so you do not lose a photo you wanted.
- Sort Drive by size. Google says to click Storage in the left menu of Drive to list files from largest to smallest (Google’s guide to managing storage in Drive, Gmail & Photos).
- Search email by attachment size. Gmail attachments share the same quota (Google’s storage help page).
- Reassess your plan last. Wait for the total to update before deciding whether to downgrade or stay.
Back up anything irreplaceable somewhere else before a large deletion pass.
Gmail Search Lines That Find the Big Files
Google’s guide to managing storage in Drive, Gmail & Photos lists these search operators for finding what to delete:
has:attachment larger:10Mfinds emails with attachments over 10 MB.filename:.pdf larger:5Mfinds PDF attachments over 5 MB.older_than:2y has:attachmentfinds attachments older than two years.
The same page notes that Drive has no built-in duplicate finder. Its manual method is to sort by name in list layout and look for identical names, especially those ending in “(1)” or beginning with “Copy of.” It also points to the Backups section of your storage management page, where you can review and delete unneeded device backups.
If WhatsApp Backups Are the Hidden Hog
Google lists WhatsApp backups among the services that share the 15 GB. For Android, Google’s guide to managing storage in Drive, Gmail & Photos suggests turning off “Include videos” under Settings > Chats > Chat backup, because videos take the most space, then tapping “Back Up now” to apply the new settings. It warns that deleting old backups at one.google.com/storage/management is permanent and that you will lose chat history if you have not made a new backup first.
The iCloud Version of the Same Cleanup
Apple Support describes where to look when iCloud is full:
- Recommended for You. On iOS or iPadOS 17 and later, open iCloud settings and tap it for suggestions on photos, large files and old backups.
- Backups. Open Backups under iCloud storage, select a device, and turn off backups for apps you don’t need or delete old backups.
- Messages. Review attachments in each conversation’s Photos section and delete what you don’t need.
- Mail. Messages with attachments use more space; iCloud Mail Cleanup can remove promotions, updates or transactions.
- Files. Delete unneeded files or folders from the Files app, Finder or iCloud.com.
Two safety notes from the same page: deleted photos and videos can be recovered from Recently Deleted for 30 days, but if you are over your storage limit, deleted items are removed immediately and cannot be recovered. Photos deleted from a shared album are also removed immediately, so Apple’s advice is to save a copy to your personal library first.
A Prompt for Planning the Cleanup
AI can help you organize the work without ever seeing your files. Copy the numbers from your storage page (not file names or contents) and paste this:
My storage is [used] of [total]. I am copying only the numbers from my storage page, not file names or contents.
By service:
- Photos: [x]
- Drive: [y]
- Gmail: [z]
- Trash and Spam: [t]
- Device backups: [b]
I want to get under [target] without paying for a bigger plan.
Please:
1. Give me a cleanup order from biggest expected savings to smallest, one action per line.
2. Show the running total after each action.
3. Tell me what to back up first.
Rules:
- Use only these numbers.
- Do not guess what is inside any service.
- Do not tell me to delete anything I have not listed.This prompt is my suggestion. Use the answer as an ordering aid, and use the official steps above for the actual deleting.
An invented example. Say your storage is 14.2 GB of 15 GB: Photos 8.1, Drive 3.4, Gmail 2.0 and Trash and Spam 0.7, which add up to 14.2. Your target is under 12 GB, so you need to free 2.2 GB. The first line should be to empty Trash and Spam, because those items still count until permanently deleted: 14.2 minus 0.7 leaves 13.5, so 1.5 GB is still to go.
The next lines come from Photos and Drive, starting with the largest files, and the running total shows when you reach the target. Remember that Google says the total can take 48 to 72 hours to update after large deletions, so recheck later before deciding on a plan. The numbers are made up.
Photos Are the Big Slice: Original Quality vs Storage Saver
Photos and videos are often the biggest slice of a shared Google storage total, and one setting decides how much room they take. Google’s help page on backup quality describes two main choices, and the difference is clear once you see it side by side.
- Original quality keeps photos and videos at the resolution they were captured in, with no reduction. Google recommends it for photos over 16 MP, videos over 1080p, and large printed banners. These uploads count toward your storage.
- Storage saver (previously called High quality) does compress: photos larger than 16 MP are downscaled to 16 MP, some may be converted to another format such as JPG, and videos above 1080p are reduced to 1080p. Some metadata, such as closed captions, may be lost. Storage saver uploads also count toward your storage, just less of it.
A third option, Express, is not available in every region. It compresses photos to about 3 MP and videos to 480p.
The helpful part is that you do not have to re-upload anything to switch. Under Settings > Manage storage, Google’s “Recover storage” section offers to convert your existing Original-quality backups to Storage saver. Google lists these limits so you can plan around them:
- You can run it only once a day.
- It does not change the quality of future uploads. To change those, go to photos.google.com/settings on a computer and pick the quality you want.
- Some files cannot be compressed, such as certain Multi-Picture Format JPGs (Android portrait-mode shots, for example), and they keep their original size. You can check an item under Details in the Info panel; the “Not eligible for Storage saver” label appears only after you have attempted a Storage saver backup.
- The option does not appear if your account has unlimited Google Photos storage.
Two details save you effort. Google says items backed up in High quality or Express before June 1, 2021 do not count toward your storage, so there is no need to convert those. And the same page notes that content may be deleted after two years of inactivity in Google Photos, so open the app now and then to keep the account active.
A way to decide (my suggestion). Keep Original quality for pictures you might print large or edit heavily, which matches Google’s own recommendation, and use Recover storage for everyday snapshots and screen recordings where the 16 MP and 1080p limits are more than enough. Run it before you buy a bigger plan, then wait for the total to update, since Google says it can take 48 to 72 hours after large deletions.
Your Phone’s Own Storage Page Is the Second Check
Cloud storage is only half the picture on an iPhone or iPad. Apple’s guide to checking storage shows where to look on the device itself.
- Open the breakdown. Go to Settings > General > [device] Storage to see recommendations and a list of apps with their storage usage. Tap an app for more detail. Apple notes that cached and temporary data might not count as usage.
- Use the recommendations. Tap Show All in the Storage section, read each description, then tap Enable to turn it on or tap the recommendation to review the contents you can delete.
- Offload instead of deleting. From an app’s detail view you can offload it, which frees the app’s storage but keeps its documents and data.
- Check Messages and Mail. Apple says Messages storage covers messages and their attachments, and Mail storage covers emails and their attachments, so both are worth a look when the total seems too high.
Apple also explains that when a device is low on storage, the system frees up space by removing items that can be downloaded again or are not needed, such as unused apps and temporary files. In practice, that means a quick pass through the breakdown above is a low-risk first step, and anything you offload can come back with its data intact.
My View on Digital Decluttering
This closing part is my opinion. Storage tends to fill through many small non-decisions, like burst photos and old screenshots, so a short cleanup twice a year is easier than one big one.
