How to Clear Cache on TikTok and Free Up Storage (iPhone and Android)

Key takeaways

• Clearing the TikTok cache removes temporary files the app stores to load videos faster, and it does not delete your account, videos or drafts.
• The quickest route on both iPhone and Android is the storage option inside TikTok's own Settings and privacy menu.
• Android also lets you clear cache from the phone's app settings, while iPhone users can offload or reinstall the app for a deeper clean.
• Drafts are stored on your device, so back up anything important before reinstalling the app.
• Clearing cache can help with lag, failed uploads and storage warnings, but the cache will build up again with normal use.

TikTok is one of the hungriest apps on most phones. It stores video data, sounds, effects and thumbnails so your feed loads instantly, and that pile grows every time you scroll. If you want to know how to clear cache on TikTok, the good news is that the app gives you a built-in option, and it takes less than a minute. This guide covers the exact steps on iPhone and Android, explains what clearing the cache does and does not delete, and shows other ways to free up storage when TikTok gets too large.

What the TikTok cache is

A cache is a store of temporary files that an app keeps so it does not have to download the same things twice. For TikTok, that means chunks of videos you have watched or are about to watch, profile pictures, sound clips, filters and effects. Caching makes scrolling feel smooth, but it comes at a cost: storage space. Over weeks of regular use, the cache can grow large enough to trigger low storage warnings.

Cached files are not your content. Your account, posted videos, likes, followers, messages and saved collections all live on TikTok's servers. That is why clearing the cache is a safe first step when you need space or the app misbehaves.

How to clear cache on TikTok from inside the app

This method works on both iPhone and Android and is the one most people should use. Menu names can change between app versions, so look for the closest match if a label is different on your phone.

1. Open TikTok and tap Profile in the bottom bar.
2. Tap the three-line menu in the top corner.
3. Tap Settings and privacy.
4. Scroll to the cache and cellular or free up space section, often listed under a heading about storage.
5. Find the Cache line, which shows how much space it uses.
6. Tap Clear next to Cache and confirm.

On the same screen you will often see a separate line for downloads. Those are videos you saved through the app. Clear them only if you no longer need them on your phone.

How to clear TikTok cache on Android from phone settings

Android also lets you clear an app's cache from the system settings. This is useful if TikTok will not open properly. Exact wording differs between phone brands.

1. Open your phone's Settings app.
2. Tap Apps, or Apps and notifications.
3. Find and tap TikTok in the list.
4. Tap Storage, or Storage and cache.
5. Tap Clear cache.

You will also see Clear storage or Clear data. That option resets the app as if it were new: it logs you out and can remove drafts and settings stored on the phone. Use it only as a last resort, after backing up drafts.

Freeing up TikTok storage on iPhone

iPhone does not offer a separate system-level cache button for most apps, so the in-app method above is your main tool. If TikTok still takes too much space, iOS gives you two deeper options.

Offload the app

1. Open the iPhone Settings app.
2. Tap General, then iPhone Storage.
3. Wait for the list to load and tap TikTok.
4. Tap Offload App and confirm.

Offloading removes the app itself but keeps its documents and data. When you reinstall from the App Store, your data comes back. This frees the space the app binary uses, though not the cache, so it is a partial fix.

Delete and reinstall

Deleting the app removes everything stored on the phone, including cache and drafts. After reinstalling, sign back in and your account content is still there. This is the most thorough clean, but back up drafts first.

What you lose and what you keep when you clear cache on TikTok

Here is a quick reference so you know what to expect.

• Kept: your account, posted videos, followers, likes, comments, messages, favorites and collections. These live on TikTok's servers.
• Kept with in-app clear: drafts and your login session, since the in-app cache option targets temporary files.
• Removed: temporary video data, cached sounds, thumbnails and effects. They download again as needed.
• At risk with deeper methods: drafts, downloaded videos and your login session, if you clear app data on Android or delete and reinstall on either platform.

Because drafts are stored locally, it is worth saving anything important before a deep clean. Open each draft and either post it with the audience set to Only you, or save the video to your device from the draft screen if the option is available. If you want to keep copies of your own public videos as files, the TikTok video downloader can help you save them before you clear downloads.

Other ways to free up TikTok storage

• Clear downloads. In the same storage screen, remove videos you saved through TikTok that you no longer need.
• Review drafts. Old drafts you will never post can take real space. Delete the ones you do not need.
• Turn off auto-save. If your posted videos are automatically saved to your camera roll, check the setting in the post screen or in your settings and turn it off if you do not need duplicates.
• Use data saver. In Settings and privacy, look for a data saver option. It lowers video quality on cellular data, which can reduce how much is cached.
• Check your camera roll. Exported edits and screen recordings for TikTok often pile up outside the app.

If the clear cache option is missing or does nothing

Occasionally the steps above do not go as planned. Here is how to handle the most common snags.

You cannot find the storage section

TikTok rearranges its settings from time to time. Open Settings and privacy and use the search bar at the top of that screen if your version has one, typing "cache" or "storage". If there is no search option, scroll slowly through the sections under general settings, since storage options usually sit near data saver and other device-related settings.

The cache size does not go down

Close TikTok completely and reopen it, then check the storage screen again. The number sometimes updates only after a restart. If it still looks high, the space may be used by downloads or drafts rather than cache, which are listed separately.

Your phone storage barely changed

Your phone may need a few minutes to recalculate free space. On iPhone, the storage screen in Settings can take a while to refresh. On Android, some phones show storage changes only after you leave and reopen the storage page.

The cache fills up again quickly

That is normal. The cache rebuilds as you watch, and heavy scrolling will grow it again within days. Turning on data saver and clearing downloads regularly helps keep it in check. If storage is a constant struggle, it may be time to move photos and videos off your phone to cloud or computer storage, since those usually take far more room than TikTok itself.

When clearing cache helps with performance

Beyond storage, clearing the TikTok cache can fix a range of small problems caused by corrupted temporary files:

• Videos that freeze, stutter or show a black screen.
• Sounds or effects that fail to load.
• Uploads that stall partway through.
• The app crashing on launch or when opening specific screens.

If problems continue after clearing the cache, update TikTok from your app store, restart your phone and switch to a stable Wi-Fi network. If an upload keeps failing and your video stays stuck with no views afterward, the cause is more likely processing or review on TikTok's side than anything on your phone, so give it a few hours before posting again.

Clearing the cache is quick, safe and reversible, and the app will simply rebuild it as you scroll. Make it part of your routine maintenance, especially before posting, and you will spend less time fighting storage warnings and more time making videos.

Frequently asked questions

Will clearing cache on TikTok delete my drafts?

Clearing the cache through TikTok's own storage setting is designed to remove temporary files, not drafts. However, drafts live on your device, so deleting or reinstalling the app can remove them. Before any deeper clean, open each important draft, post it privately or save it to your device so you do not lose work.

Does clearing TikTok cache log me out?

Clearing the cache from inside TikTok does not normally log you out. Clearing the app's data or storage on Android, or deleting and reinstalling the app on either platform, usually does. Make sure you know your login method and password before trying those deeper options, so you can sign back in easily.

How often should I clear the TikTok cache?

There is no fixed schedule. Clear it when the app feels slow, uploads keep failing, or your phone warns about low storage. Some people do it monthly as routine maintenance. Clearing very often is unnecessary, because the app rebuilds the cache as you watch and the first few videos may load slightly slower afterward.

Why is TikTok taking up so much storage?

TikTok saves pieces of videos you watch, thumbnails, sounds and effects so it can load content quickly. It also keeps drafts and any downloaded videos. The more you scroll, the larger this gets. The app's storage screen usually shows how much is cache versus downloads, which helps you decide what to clear.

Will clearing cache fix TikTok not working properly?

It often helps with glitches caused by corrupted temporary files, such as videos failing to load, sounds not playing, or uploads freezing. It will not fix server outages, account restrictions or a poor connection. If problems continue after clearing cache, update the app, restart your phone and try a different network.
