When Google One says your 15 GB is full, the quickest way to get space back is to empty the trash in Gmail, Drive and Photos, remove the largest videos, delete emails with big attachments, and clear duplicate photos, in roughly that order. Those four steps take under an hour and often return several gigabytes. Converting photos to Storage saver, clearing screenshots and old backups, and tidying Drive come next. Only after all nine should you decide whether paying for more storage is worth it.
First, see where the 15 GB went
The free 15 GB is shared by Gmail, Google Drive and Google Photos, so the warning does not tell you which one is the problem. Open one.google.com/storage. The bar at the top shows the split. Photos is usually the largest slice, Gmail the second, Drive a distant third, but older accounts and work-heavy accounts can be the other way around.
The nine actions below are ranked by how much space they tend to return for the time they take. Start at the top and stop when you have enough headroom.
The nine ways, ranked
1. Empty the trash in all three services
Time: two minutes. Items in the trash still count toward your storage until the trash is emptied, and each service keeps trashed items for 30 days. If you have deleted anything recently, this is free space waiting for a click.
- Google Photos: Library, then Trash, then Empty trash.
- Gmail: Trash in the left-hand menu, then "Empty Trash now". Do the same for Spam.
- Google Drive: Trash in the left-hand menu, then "Empty trash".
Glance through each before you confirm. Emptying the trash is the only permanent step on this list. More in Google Photos trash explained.
2. Remove the largest videos in Google Photos
Time: ten minutes. Video is where the gigabytes hide. In Google Photos, open Settings, then Manage storage, then Review and delete, then Large photos and videos. The list is sorted by size, so the first screen is the heaviest files you own. Screen recordings, long concert clips and the same school play filmed from three angles are the usual suspects. Download anything you want to keep to a computer or external drive, then move the rest to the trash.
3. Delete emails with large attachments
Time: fifteen minutes. In the Gmail search box, type larger:10M and press Enter. Every email with attachments over 10 MB is listed. Old accounts often have hundreds. Save any attachment you still need to Drive or your computer, select the rest and delete. Try larger:5M afterwards for a second pass. Then empty the Gmail trash again.
4. Clear duplicate photos
Time: twenty to thirty minutes, mostly waiting for a scan. Years of automatic backup leave a layer of duplicates: the same photo backed up from the camera roll and from WhatsApp, bursts of near-identical frames, edits saved as new files, copies re-saved from shared albums. They are the same size as the originals and they carry no new memories, which makes them the safest thing in your library to remove. Google Photos has no duplicate finder, so you need a tool or patience. The causes are explained in why Google Photos has duplicates.
By hand, open photos.google.com on a computer, search a date, select the copies and trash them. For a large library, Doppelgone is a free Chrome extension that scans your library on photos.google.com, groups exact duplicates, similar shots and bursts, keeps the best shot of each set, and moves the rest to the trash once you approve the list. There is a one-click undo, and favourites and videos are never touched. Your photos never leave your device. In our testing on a real library of about 15,000 photos, Doppelgone found roughly 4 GB of duplicates. Step-by-step in how to delete duplicate photos in Google Photos.
5. Convert Original quality photos to Storage saver
Time: five minutes, then processing in the background. If your photos were backed up in Original quality, the Manage storage page in Google Photos offers a "Recover storage" option that compresses existing photos to Storage saver quality (photos reduced to 16 megapixels, videos to 1080p). For screens and ordinary prints the difference is hard to spot, and it can roughly halve what your photos use. It cannot be undone, so skip it if you print large or edit seriously. Read Storage saver vs Original quality first.
6. Delete old backups and large files in Drive
Time: ten minutes. Open drive.google.com/drive/quota to see your files sorted largest first. Forgotten videos, zips and installers sit at the top. Check Backups in the left-hand menu for old phone and WhatsApp backups. Files shared with you do not count, so leave those alone. Empty the Drive trash afterwards.
7. Delete promotional, social and update mail
Time: five minutes. Search category:promotions in Gmail, select all, and delete. Repeat for category:social and category:updates. Each message is small, but there can be tens of thousands. If you are nervous, add older_than:1y to the search to keep the last year.
8. Clear screenshots and blurry photos
Time: fifteen minutes. The same Review and delete page in Google Photos lists screenshots and blurry photos. Boarding passes, directions and chat snippets from years ago have done their job. Review in batches and trash what you do not need.
9. Remove photos you only keep by habit
Time: as long as you like. Receipts, whiteboards, parking spots, photos of documents you have since filed. These are the long tail. Search Google Photos for "receipt", "document" or "whiteboard" and you will find more than you expect. This step returns the least per minute, which is why it is last.
How much each step tends to return
These are rough patterns from typical accounts, not guarantees. Your mix will differ.
| # | Action | Time | Typical gain |
|---|---|---|---|
| 1 | Empty all trashes | 2 min | Whatever you deleted recently; can be several GB |
| 2 | Largest videos | 10 min | Often 1 to 5 GB |
| 3 | Emails larger than 10 MB | 15 min | Often 1 to 3 GB on an old account |
| 4 | Duplicate photos | 20 to 30 min | Can be several GB on a large library |
| 5 | Convert to Storage saver | 5 min plus processing | Can roughly halve Original quality photos |
| 6 | Drive files and backups | 10 min | Varies widely; large if there are videos or backups |
| 7 | Promotions and social mail | 5 min | Often hundreds of MB |
| 8 | Screenshots and blurry photos | 15 min | Often hundreds of MB |
| 9 | Habit photos | Open-ended | Small per photo, adds up over time |
Things that do not help
A few actions feel like they should free Google storage and do not.
- Deleting photos from your phone. The "Free up space" button in the Google Photos app removes local copies that are already backed up. Your Google One figure stays the same.
- Removing files from "Shared with me" in Drive. They were never counted against you.
- Deleting photos a partner shares with you. They live in the partner's storage.
- Archiving photos. Archive hides them from the grid; they still count.
- Moving photos into albums or Locked Folder. Same storage, different view.
After the clean-up
Remember to empty the trash once more when you are done, and give Google a few minutes to update the figure. Then turn off the sources that fill the account up in the first place: in the Google Photos app, disable backup for WhatsApp, Telegram, Screenshots and Downloads folders, and stop any second backup path such as the desktop uploader duplicating what your phone already sends.
When to stop and pay
If you have done the nine steps and you are still within a gigabyte or two of the limit, the honest answer is that 15 GB is too small for how you use it. That is common for families on a shared account, anyone who shoots a lot of video, and anyone who wants Original quality. Google One plans start at 100 GB. Do the clean-up first anyway, so you buy the smallest plan that gives you comfortable headroom rather than paying to store duplicates and screenshots. The broader discussion is in how to free up Google storage without paying.
Frequently asked questions
Why does Google One say storage is full when I have deleted things?
Deleted items sit in the trash of Gmail, Drive or Photos for 30 days and still count until the trash is emptied. Empty all three, then wait a few minutes for the figure to update.
Which of the three services usually uses the most space?
For most personal accounts it is Google Photos, because phones back up everything automatically. Gmail is usually second, driven by old attachments. Drive is often the smallest unless you store videos or phone backups there. Your Google One storage page shows the exact split.
Do duplicate photos really use much space?
Each duplicate is the same size as the original, so a few thousand copies on a long-running library can add up to several gigabytes. Because they are copies, removing them loses nothing, which is why they rank high on this list.
Is it better to buy Google One than to clean up?
Cleaning up first is almost always worth it, even if you end up paying. It takes under an hour, and it means you buy the smallest plan that fits what you actually want to keep instead of paying every month to store copies and screenshots.
What to do next
Empty the three trashes and check your Google One storage page; that alone may be enough. If photos are the bulk of your 15 GB, run a free scan with Doppelgone to see how much of it is duplicates before you spend anything on more storage.
