How to Clear Cache on TikTok
A real control that genuinely frees gigabytes, and a folk remedy for about six problems it has never fixed.
How to clear cache on TikTok: open your profile, tap the three-line menu at the top right, go to Settings and privacy, then Free up space, and tap Clear next to Cache. It frees storage in seconds and keeps your drafts, saved videos and account, but it does not change your reach, your views or your For You feed.
It takes a second and frees anywhere from a few hundred megabytes to several gigabytes, because TikTok stores every video you scrolled past.
Nothing is lost. Your drafts, your saved videos, your account, your following list and your watch history all survive. The cache holds only downloaded copies of videos you already watched.
What it does not do is change your reach, lift a restriction, fix views stuck at zero, or reset your For You feed — despite being recommended constantly for all four.
That last point is worth going at directly, because the advice is everywhere and it wastes a lot of people's time.
The cache is a local store of video files on your phone. It exists so that scrolling back up does not re-download. It is read by your device and by nothing else.
Your reach, your video performance, any restriction on your account, and what the For You feed selects are all computed on TikTok's servers from your account's history. None of it is in the cache, and deleting local files is not visible to the system that decides those things. The view counter under each video is kept there too, and it is the public number TikTok views add to; nothing you delete from your phone moves it in either direction.
The reason the advice spreads anyway is that it sometimes appears to work. Clearing the cache forces the app to re-fetch everything, which resolves genuine display glitches — a video that will not play, a profile picture stuck on the old one, an interface element rendering wrong. Those are real fixes, and they get generalized into fixes for everything.
The distinction that holds: if the problem is what you are seeing on your own screen, the cache is a reasonable thing to try. If the problem is what other people see, or what the platform is doing with your content, the cache is not involved and clearing it is a way of feeling busy.
Where the cache button lives
Profile, then the three lines at the top right, then Settings and privacy.
Scroll to the Cache and cellular data section and open Free up space. TikTok shows the current cache size with a clear button beside it.
On Android the system settings also offer a cache clear for the app, under Apps, then TikTok, then Storage. That is a blunter version and clears slightly more.
On iPhone there is no system-level equivalent, so the in-app button is the only clean way. Offload App in the iPhone storage settings removes the app but keeps its documents and data, so it frees little of what the cache holds. Deleting and reinstalling does clear everything, and it also deletes your drafts, which is a poor trade for storage.
There is no automatic schedule and no setting to cap the size, which is why it grows until somebody notices.
What survives and what does not
Survives: your account, drafts, saved videos and collections, following and followers, liked videos, watch history, and any downloaded sounds.
If a low likes count is what puts visitors off, TikTok likes are sold here per order from a public link, with no login asked.
Goes: downloaded copies of videos you scrolled past, thumbnails, and temporary files.
On Android, clearing app data rather than cache is a different and much more destructive operation — it signs you out and can lose unsaved drafts. The two sit next to each other in system settings and are easy to confuse.
Drafts are the thing worth protecting. They live on the device, not in your account, so a drafts folder is lost if the app is uninstalled, whatever anybody says about them syncing.
The problems it genuinely fixes
Videos that will not play or load as a gray square.
A profile picture or username that is stuck showing an old version.
Interface elements rendering in the wrong place or not responding.
The app being unusually slow to open or scroll, on a device that is short of storage.
All four are display problems on your own device, which is precisely the category the cache belongs to.
The problems it does not fix
Views stuck at zero. That is a decision made on TikTok's servers about your video.
Low reach or a sudden drop in performance. Also server-side, also unaffected.
A restriction, a strike, or an account under review. These live on the account.
A For You feed full of content you dislike. The feed is built from your watch history, which is on the server and is not cleared. There is a separate control for that — refresh your For You feed, in Settings under Content preferences — and it is the one people actually want.
And a missing feature, such as repost or photo comments. Those are account eligibility, not local state.
If you want the comments count on TikTok to move faster than it would on its own, you can buy TikTok comments with only a public link; it raises the number, not the reach.
If the reason you went looking for the cache was a stalled video, why a TikTok video sits at zero views walks through the causes that actually apply, and how the TikTok algorithm works explains where reach is decided. The view total itself is a public counter, and TikTok views raise that number on a video you choose; they do not change how TikTok distributes it. Everything else on the platform is gathered on the TikTok hub.
The setting most people were looking for
Refreshing the For You feed is in Settings and privacy, under Content preferences, and it does what clearing the cache is wrongly credited with.
It tells TikTok to discount your existing watch history and start learning again. The feed goes generic for a few days and then re-forms around whatever you watch next.
It is drastic and not reversible, so it is worth doing deliberately rather than as a troubleshooting step. Resetting the TikTok For You feed covers what the refresh keeps and what it throws away.
There is also the per-video control: hold down on anything and choose not to see similar content, which is slower and does not throw away the parts of your feed that work.
Questions people ask about clearing TikTok's cache
Will clearing the cache delete my drafts?
No. Clearing the cache keeps drafts, saved videos and your account. Clearing app data on Android is a different, destructive option and can lose drafts.
Does clearing the cache fix low views?
No. Views and reach are decided on TikTok's servers from your account history. The cache is local video files and is invisible to that system.
How much space does it free?
Anywhere from a few hundred megabytes to several gigabytes, depending on how much you have scrolled since the last clear.
Does it reset my For You feed?
No. The feed is built from your watch history on the server. The control you want is Refresh your For You feed, under Content preferences.
Do I have to log in again afterwards?
No. Clearing the cache does not sign you out. Clearing app data on Android does.
How often should I do it?
Only when storage is short or the app is misbehaving visually. There is no benefit to doing it routinely.
