Google gives every account exactly 15 GB of free storage, but that quota is shared across Gmail, Google Drive, and Google Photos. Once it fills up, new emails can’t arrive, Drive stops syncing, and photo backups pause — all three services halt at the same time.
Before paying for Google One, try these five steps. Most users recover several gigabytes in under 15 minutes without losing anything they actually want to keep.
Quick Answer
Your 15 GB of Google storage is shared between Gmail, Drive, and Google Photos. Delete large Gmail attachments, empty Trash in all three services, compress Photos originals using Google’s free Storage Management tool, and remove unnecessary Drive files. These steps cost nothing and typically recover several gigabytes in minutes.
Where Your Storage Goes
Visit one.google.com/storage first. The page breaks down exactly how much space each service is consuming so you know where to focus first.
| Service | Biggest space hogs | Quickest win |
|---|---|---|
| Gmail | Emails with large attachments; Spam and Trash folders | Search has:attachment larger:5m and delete |
| Google Drive | Old videos, duplicate files, large downloads | Sort Storage view by file size; delete top offenders |
| Google Photos | Original-quality videos and RAW images | Convert to Storage Saver quality |
1. Delete Large Emails in Gmail
Gmail attachments are often the single biggest drain — a handful of old project files or marketing PDFs can quietly eat 2–3 GB.
Find and remove oversized messages
- Open Gmail in a browser (not the mobile app).
- In the search bar, type has:attachment larger:5m and press Enter. This lists every email with an attachment over 5 MB.
- Click the top checkbox, then click Select all conversations that match this search.
- Click the Trash icon. Repeat the search with larger:10m and larger:25m to catch the heaviest files first.
- In the left sidebar, click Spam → Delete all spam messages now.
- Click Trash → Empty Trash now. Deleted messages still count toward your quota until Trash is emptied.
Pro tip: Set up a Gmail filter (Settings → See all settings → Filters and Blocked Addresses → Create a new filter) to auto-delete newsletters older than 30 days. It keeps storage from creeping back up.
2. Free Space in Google Photos
A single minute of 4K video can top 400 MB, and original-quality RAW images from a modern smartphone run 20–30 MB each. Photos is often the hidden culprit behind a full quota.
Convert originals to Storage Saver
- Open Google Photos and tap your profile picture → Photos settings → Backup.
- Under Upload size, select Storage saver. Future uploads compress automatically.
- To compress existing originals, open google.com/photos/storage and tap Compress existing photos and videos. Quality is virtually indistinguishable for everyday prints up to 8×10 inches.
Troubleshooting tip: If the Compress button is greyed out, your library is already on Storage Saver. Confirm by checking Upload size in the Backup settings.
3. Remove Unnecessary Files from Google Drive
Old project folders and duplicate downloads accumulate without being noticed. Sorting by file size cuts straight to the biggest offenders.
Clear by file size
- Go to drive.google.com and click Storage in the left sidebar. Drive lists your files from largest to smallest.
- Right-click anything you no longer need and select Move to trash.
- Click Trash in the sidebar → Empty trash.
Files others have shared with you don’t count against your quota — only files you own do.
4. Use Google’s Storage Management Tool
Google’s own tool at one.google.com/storage/management automatically surfaces easy wins: blurry and duplicate photos, large Gmail attachments, and oversized Drive items. Open it, review each suggested category, and delete what you no longer need. Most users recover 1–2 GB here without hunting through folders manually.
5. Empty Trash Across All Three Services
Deleted files count against your quota until each Trash folder is permanently emptied — this step is easy to overlook.
- Gmail: left sidebar → Trash → Empty Trash now.
- Google Drive: left sidebar → Trash → Empty trash.
- Google Photos: Library → Trash → three-dot menu → Empty trash.
After emptying all three, refresh one.google.com/storage — the quota bar updates within a few minutes.
If Drive is clear but syncing still isn’t working, see our guide on Google Drive not syncing. Running low on device storage at the same time? We also cover clearing Android storage and freeing up iPhone storage.
Common Mistakes to Avoid
- Not emptying Trash after deleting. Items moved to Trash still use quota for up to 30 days. Always finish by emptying Gmail, Drive, and Photos Trash folders.
- Deleting files shared with you. Shared files don’t count against your quota. You can leave them in place — only files you own use your 15 GB.
- Checking quota immediately after compressing Photos. The background compression job can take several hours on a large library. Wait before concluding it didn’t work.
- Ignoring the Spam and Promotions tabs. Both fill with attachment-heavy marketing emails. A quick sweep of each tab often frees hundreds of megabytes.
- Paying before trying the free fixes. Google’s Storage Management tool resolves most full-quota situations at no cost. Run through all five steps first.
Frequently Asked Questions
Do Google Docs, Sheets, and Slides count against my storage?
No — files created in Google’s native formats (Docs, Sheets, Slides, Forms) don’t use any of your 15 GB. Only uploaded files such as PDFs, images, Word documents, and videos count.
How long before freed space shows up on my quota?
The storage bar at one.google.com/storage usually updates within a few minutes of emptying Trash, but can take up to 24 hours in some cases.
Will converting to Storage Saver ruin my photo quality?
For everyday prints up to 8×10 inches, the difference is negligible. If you regularly print large-format photos, keep originals and recover space from Gmail or Drive instead.
I cleared everything and I’m still over the limit — what now?
Check whether you have a second Google account; each gets its own 15 GB and you can move files there. Otherwise, the 100 GB Google One plan is an affordable upgrade if the free fixes aren’t enough.
Does Google Photos count if I turn off Backup?
Photos already backed up before you turned off Backup still count. Turning off Backup only prevents new uploads — it doesn’t remove what’s already stored.
Conclusion
Google’s 15 GB free tier fills faster than most people expect, but you rarely need to pay to fix it. Start at one.google.com/storage to see the breakdown, work through the five steps, and finish by emptying Trash in Gmail, Drive, and Photos. In most cases, that clears the warning and restores normal access across all three services.
Try the Storage Management tool first — it takes under two minutes and often recovers more space than expected.
