Why Is Google Photos Using So Much Storage?
Short answer
Google Photos is usually large because backup is set to Original quality, which stores full-resolution photos and 4K video at full size — one minute of 4K is roughly 350MB. Switch to Storage saver for future backups, then open Photos settings → Manage storage, which lists large videos, blurry shots and screenshots as separate categories you can clear in bulk.

Google Photos routinely accounts for most of a full 15GB account, and the reason is rarely the number of photos. It’s the settings those photos were backed up under, and a small number of video files.
The two settings that decide everything
Open the Photos app, tap your profile picture, then Photos settings → Backup → Backup quality. You’ll see two options:
| Setting | What it stores | Space per photo |
|---|---|---|
| Original quality | The exact file from your camera, untouched | 3–8MB per photo, 350MB+ per minute of 4K video |
| Storage saver | Recompressed, capped at 16MP and 1080p video | ~1–2MB per photo, ~30MB per minute of video |
For viewing on a phone or a laptop screen, the difference between these is essentially invisible. Storage saver still produces photos large enough to print at standard sizes.
If you’re on Original quality and don’t specifically need it, switching is the single highest-impact change available — but note it only affects future backups.
Find the biggest items
Google has a built-in tool for this and it’s genuinely good.
- Open the Photos app and tap your profile picture.
- Tap Photos settings → Manage storage (on some versions, Free up account storage).
- You’ll see your total, then categories Google has identified for you.
The categories usually include:
- Large photos and videos — sorted biggest first. This is where the gigabytes are.
- Blurry photos — shots the algorithm scored as out of focus.
- Screenshots — often thousands, almost never worth keeping.
- Unsupported videos — files that failed to process and are just taking space.
Work through Large photos and videos first. In most accounts, clearing twenty video files recovers more than deleting ten thousand photos.
On the web
Go to photos.google.com/storage for the same tool with a larger view, which is easier for bulk selection. Click the first item, scroll down, then shift-click the last to select a range.
Deal with the video problem
Video is the real cost driver and deserves its own pass.
In Manage storage → Large photos and videos, the list is sorted by size. Look for:
- Long clips you recorded by accident — pocket video, a camera left running.
- Screen recordings, which are enormous and rarely needed after a week.
- Videos you’ve already shared elsewhere and don’t need a second copy of.
- 4K footage of ordinary moments where 1080p would have been fine.
Download anything you want to keep to a computer or external drive before deleting. Saving it to Google Drive does not help — Drive draws on the same 15GB.
Clear the categories that are pure waste
Three categories can usually be emptied with minimal thought:
Screenshots. Search screenshots in the Photos search bar. Most people have
thousands, and the useful lifespan of a screenshot is about two days. Select all and
delete.
Blurry photos. The detection is conservative — it flags genuinely unusable shots, not merely imperfect ones. Scan quickly then delete the lot.
Unsupported videos. These are files Google couldn’t process. They’re occupying space and can’t be played. Nothing is lost by removing them.
The duplicates Google doesn’t catch
Google Photos deduplicates identical files, so uploading the same photo twice stores it once. What it doesn’t do is detect near-duplicates.
Burst shots are the big one. Twelve frames of the same moment are twelve separate full-size images. So are the five attempts at a group photo where someone blinked.
There’s no automated tool for this. The practical approach is to open your largest albums, scan for runs of near-identical frames, and keep one from each run. An hour of this on a photo library spanning years is often a gigabyte or two.
Empty the bin
Deleted photos go to the bin and continue to count against your quota for 60 days — longer than Gmail or Drive.
Tap the menu, choose Bin (or Trash), then Empty bin.
Nothing you delete frees any space until you do this.
The one-time “recover storage” option
Google occasionally offers a tool that recompresses all your existing Original quality photos down to Storage saver, which can free a large amount at once.
Two warnings before using it:
- It’s irreversible. The originals are permanently replaced by compressed versions.
- It applies to everything, including photos you may want at full resolution.
If your originals also exist on a computer or a drive, it’s a reasonable choice. If Google Photos is your only copy, don’t.
Stop it refilling
- Set backup quality to Storage saver.
- Turn off backup for folders you don’t need — in Backup → Back up device folders, screenshots and app-downloaded images are commonly on by default.
- If you shoot a lot of video, consider backing up video to a separate service or drive entirely, and let Google Photos handle stills only.
Freeing phone space without losing the photos
A separate and frequently confused question. Google Photos has a Free up space function that removes local copies of photos already backed up — it does not delete them from your account.
