How to Clear Google Maps Cache and Offline Areas
To clear the Google Maps cache, open the app, tap your profile picture > Settings > About, terms & privacy > Clear application data on both iPhone and Android; to remove downloaded maps, go to profile picture > Offline maps and delete each area. This guide is for anyone whose phone is low on space and has noticed that Google Maps quietly grew into one of the biggest apps on the device.
TL;DR
- The in-app Clear application data control wipes the Maps cache on both iOS and Android without logging you out.
- Downloaded Offline maps are stored separately and can be hundreds of megabytes each — delete them in the Offline maps screen.
- On Android you can also clear cache from Settings > Apps > Maps > Storage, which iOS does not offer.
- Clearing the cache fixes most glitches (blank tiles, stuck location, search errors) and frees space, but it grows back as you use the app.
- The cache is temporary data only — your saved places, lists, and Timeline live in your Google account and are never touched.
Why does Google Maps take up so much storage?
Google Maps stores three different kinds of data on your phone, and only one of them is true junk. The first is the cache: map tiles, satellite imagery, and search results the app downloads as you pan and zoom, kept so the same area loads instantly next time. The second is offline maps, which are regions you deliberately downloaded for use without a connection — these are the heaviest. The third is your account data (saved places, reviews, Timeline), which is synced from Google and barely uses local space.
Over months of daily use, the cache and offline areas can balloon to a gigabyte or more. If you want to see exactly where your storage is going first, check our guide on how to find which app is using the most storage on your phone.
| Data type | What it is | Safe to clear? | Where to clear |
|---|---|---|---|
| Cache | Recently viewed tiles, images, searches | Yes | Clear application data |
| Offline maps | Regions you downloaded on purpose | Yes, but you lose offline access | Offline maps screen |
| Account data | Saved places, lists, Timeline | Not local — leave it | Synced from Google |
How do I clear the Google Maps cache on iPhone?
iOS does not let you clear an individual app's cache from the system Settings, so you have to do it inside Google Maps itself.
- Open the Google Maps app and tap your profile picture in the top-right corner.
- Tap Settings.
- Scroll down and tap About, terms & privacy.
- Tap Clear application data.
- Confirm when prompted.
This removes cached tiles and search history but keeps you signed in and leaves your saved places intact. If Maps was glitching — blank gray tiles, a frozen blue dot, or search that won't load — this usually fixes it on the spot. For the broader picture on what app caches are and when clearing helps, see what is app cache and when is it safe to clear.
How do I clear the Google Maps cache on Android?
Android gives you two routes. The in-app one matches iPhone:
- Open Google Maps and tap your profile picture.
- Tap Settings > About, terms & privacy > Clear application data.
- Confirm.
The system route is often faster and clears a bit more:
- Open the phone's Settings app.
- Go to Apps (or Apps & notifications > See all apps).
- Tap Maps.
- Tap Storage (or Storage & cache).
- Tap Clear cache.
Use Clear cache, not Clear storage (sometimes labeled Clear data). Clear storage resets the app completely and signs you out, which you usually don't want just to free a little space. If you're cleaning up several apps this way, our Android storage checklist walks through the safe order.
How do I delete offline maps to free the most space?
Offline maps are almost always the biggest chunk of storage Google Maps uses, because each downloaded region includes detailed street data and place names. Deleting the ones you no longer need frees far more than clearing the cache.
- Open Google Maps and tap your profile picture.
- Tap Offline maps.
- You'll see each downloaded area with its size and expiry date.
- Tap the area you want to remove, then tap Delete.
- Repeat for every area you no longer need.
While you're there, tap the gear / settings icon on the Offline maps screen and check Download preferences. Setting it to Over Wi-Fi only stops Maps from quietly re-downloading large updates on cellular. Note that offline areas auto-expire and refresh on their own, so it's worth deleting any you only needed for a single trip.
Is it safe to clear the Google Maps cache?
Yes — clearing the cache is safe and reversible by normal use. The cache is purely temporary data, so the only "cost" is that the next few maps load a little slower while the app rebuilds it. Here's the honest breakdown of what each layer does:
- What the OS does natively: iOS and Android both rely on the app to manage its own cache, but Android additionally exposes Clear cache in system Settings. Neither OS will delete your downloaded offline maps for you — you have to do that manually inside the app.
- What a cleaner like Cleanor adds: Cleanor scans your whole phone and surfaces which apps (Maps included) are the heaviest, so you know where to focus, and it helps you clear the real space hogs — duplicate photos, near-identical bursts, and large videos that the OS storage screen buries. It points you to the right native control rather than promising magic.
- What Cleanor cannot do: No third-party app can reach inside Google Maps and delete its cache for you on iOS — Apple's sandbox forbids it, and any app claiming otherwise is overpromising. Clearing the Maps cache still has to happen with the in-app Clear application data button. Be cautious with cleaner apps that claim to wipe other apps' internals; for how to judge them, read the truth about cleaner apps and whether they're safe to use.
FAQ
Will clearing the cache delete my saved places or Timeline?
No. Saved places, lists, labeled locations (Home and Work), and your Timeline are stored in your Google account and synced to the cloud, not in the local cache. Clearing application data only removes temporary map tiles and recent searches, and you stay signed in.
Why does Google Maps storage grow back after I clear it?
That's normal. The cache exists to speed up the maps you view, so as soon as you start panning, searching, and navigating again, Maps rebuilds it. There's no setting to disable caching entirely — the practical fix is to clear it occasionally and delete offline areas you no longer use.
Does deleting offline maps remove them from my account?
No. Offline maps are a per-device download, not an account-wide setting. Deleting an offline area on your phone simply removes that local copy; you can re-download it any time, and it doesn't affect other devices signed into the same Google account.
What's the difference between Clear cache and Clear storage on Android?
Clear cache removes only temporary files and is safe to do often. Clear storage (or Clear data) wipes everything the app saved locally, resets its settings, and signs you out of Google Maps, so you'd have to set it up again. Stick with Clear cache unless the app is badly broken.
The bigger storage picture
Clearing the Google Maps cache and deleting stale offline areas can reclaim a surprising amount of space, but app caches are rarely the thing that's actually filling your phone — photos, videos, and duplicates almost always are. If your storage bar is still in the red, see our full walkthrough on how to clean up phone storage, and on iPhone, Cleanor for iOS can find the duplicate and near-identical shots that the built-in storage screen hides. For a complete plan, start with storage full — what should I delete first.
