To clear TikTok and Instagram storage without losing drafts, clear only the app cache — never the app data — because cache holds redownloadable videos while data and reinstalls can wipe unpublished drafts and local files. TikTok has a built-in Free up space tool that targets cache safely; Instagram is best cleared via cache only.
TL;DR
- TikTok and Instagram grow to several GB because they aggressively cache scrolled video.
- Clearing cache is safe and keeps your drafts; clearing data or reinstalling can delete them.
- TikTok: use Settings and privacy › Free up space › Clear cache.
- Instagram: clear cache only — it has no in-app cache clearer, so use system settings on Android.
- On iPhone, neither app exposes a cache clearer, so offloading is the safe equivalent.
Why do TikTok and Instagram use so much storage?
Short-video apps preload content so scrolling feels instant, and that cached media is the main reason TikTok and Instagram balloon to multiple gigabytes. The weight comes from cached watched videos, downloaded effects and filters, and saved drafts and local app files. The app keeps growing even if you never deliberately save anything to your gallery — the cache fills on its own as you browse.
Cache vs. data: which is safe to clear?
This distinction decides whether your drafts survive:
| Action | What it removes | Drafts at risk? |
|---|---|---|
| Clear cache | Temporary preloaded video, thumbnails | No — safe |
| Clear data / storage | All local app state, login, settings | Yes — likely deletes drafts |
| Uninstall + reinstall | Everything stored only on-device | Yes — deletes local drafts |
If the button says cache, you are removing temporary weight. If it says data, storage, or the step involves uninstalling, stop and confirm what local-only content could disappear. This is the same rule explained in clear cache vs. clear data on Android.
How to clear TikTok cache (keeping drafts)
TikTok gives you the cleanest built-in route, which only touches cache:
- Open TikTok.
- Tap your Profile, then the menu (☰) in the top corner.
- Go to Settings and privacy.
- Open Free up space.
- Tap Clear next to Cache.
This is the low-risk step when the app is bloated but your drafts still matter. Drafts in TikTok are stored separately from cache, so this will not remove them — but never clear app data from system settings, as that can.
How to clear Instagram cache (keeping drafts)
Instagram does not include an in-app cache clearer, so the platform changes the steps:
- Android: go to
Settings › Apps › Instagram › Storageand tap Clear cache (not Clear data / Clear storage, which wipes local state). - iPhone: there is no per-app cache button. Use
Settings › General › iPhone Storage › Instagram › Offload App, which clears the cached footprint while keeping documents and data, then reinstall — but back up any unposted drafts first, because reels drafts can live only on-device.
Is clearing the cache safe for unpublished work?
Clearing the cache is safe and does not delete drafts — cache holds only temporary, redownloadable media. The real risk is the reset path: clearing app data, choosing Clear storage on Android, or uninstalling can remove drafts and any content saved only locally. When in doubt, export or post-to-private a draft before any step that mentions data, storage, or reinstalling.
What if cache cleanup isn't enough?
If TikTok or Instagram is just one part of a fuller phone, the durable fix is category cleanup rather than fighting one app forever. Continue with these guides:

FAQ
Will clearing TikTok cache delete my drafts?
No. Clearing TikTok cache through Free up space removes only temporary cached video and keeps your drafts, which are stored separately. Clearing app data from system settings can delete them.
Does clearing the cache delete my Instagram or TikTok drafts?
No — clearing the cache never deletes drafts on either app, because drafts are stored in the app's data, not its cache. What does delete them is clearing app data/Clear storage on Android, or uninstalling. On iPhone, offloading keeps drafts; a full delete-and-reinstall can lose Reels drafts that live only on-device, so post them privately or export first.
Does Instagram have a clear-cache button?
No. Instagram has no in-app cache clearer. On Android, clear its cache via Settings › Apps › Instagram › Storage › Clear cache; on iPhone, offload the app instead.
How much space can clearing these apps free?
It varies with usage, but heavy scrollers often reclaim 1–5 GB from each app's cache alone. The footprint rebuilds as you keep watching content.
Why does the app fill up again after I clear it?
Because both apps re-cache video as you scroll. Reducing auto-play and data-saver settings slows it down, but cache regrowth is normal.
Reclaim space without the guesswork
Manually clearing app caches helps, but duplicates and large videos usually take up far more. Cleanor for iPhone scans your phone locally to surface the biggest space-wasters — no uploads, nothing leaves your device.
