What the button does
In the Google Photos app, your profile menu offers 'Free up space'. Tap it and the app finds photos and videos on the device that have already been backed up, then deletes those local files. The cloud copies stay exactly where they are.
The result is more room on your phone. Open one of those photos afterwards and it streams from Google Photos instead of loading instantly from local storage. Nothing is lost, and nothing is reclaimed on your Google account either.
This is a genuinely useful feature — for the problem it solves. If your phone is out of space, it is the fastest fix available. If the message you saw was about Google storage, it is the wrong tool entirely.
Why people run it and see no change
The phrasing does the damage. 'Free up space' sounds like it addresses whatever space warning brought you there, and the two warnings look similar at a glance: one says your phone is full, the other says your Google account is full.
Google One counts what is stored in the cloud across Photos, Drive and Gmail. Free up space touches none of that. So the sequence people describe — run it, see gigabytes freed on the phone, check one.google.com, find the number identical — is exactly what should happen.
If your goal is to stop the storage warnings in Gmail and Drive, or to avoid a paid plan, you need to remove things from the cloud. The order to do that in is laid out on the storage-full checklist.
The three settings people mix up
Free up space is local-only, as described. Storage saver is a backup setting that compresses new uploads from the moment you enable it, leaving everything you have already uploaded untouched — it slows future growth rather than reversing past growth.
Recover storage is the one that actually shrinks an existing library. It re-compresses photos and videos you have already uploaded, replacing the originals. It frees a meaningful amount on an original-quality library, and it cannot be undone.
The practical rule: enable Storage saver early, run Free up space when your phone is full, and treat Recover storage as the last step after every reversible cleanup has been done.

There is no duplicate finder anywhere in the product. Google Photos refuses to back up a byte-identical file, but that check runs once, at upload, and compares raw bytes. A crop, a resize, a format change, or a round trip through a messaging app produces a file it treats as entirely new.
Nor is there any deduplication between Google Photos and Google Drive. The two share a single quota and keep separate indexes, so a photo sitting in both is stored twice and billed twice, with no surface anywhere that tells you.
That gap is what third-party perceptual-hash tools exist to fill. AiCleanerPro Cloud scans thumbnails across both services with read-only access, groups exact and near-duplicates, marks the best copy, and deletes only what you confirm — with everything routed through the 60-day Trash.
A cleanup order that actually works
Empty the Trash first. Photos you deleted in the last 60 days are still consuming quota, and clearing them takes seconds. This alone resolves the warning for a surprising number of people.
Then run Review and Delete for blurry shots, old screenshots and long videos, and do a duplicates pass across Photos and Drive. All of these are reversible for 60 days, so you can be decisive without risk.
Only after that should you consider Recover storage. Doing it in this order means you stop as soon as you are back under the limit, without having permanently re-compressed a library you might have kept at full quality.
