How to Clear TikTok Cache (2026 Guide for Phone and PC)

Quick Summary

• TikTok stores every video you watch as cached data - a new install can balloon to several gigabytes in just a few days. Clearing it does not affect your For You recommendations.
• On phone, you need to do it in three places: the hidden Watch History (Search → type "."), Settings → Free up space, and your phone's Apps → TikTok → Storage.
• On PC, there is no in-app "clear cache" button. You clear it through your browser (Chrome, Edge, Firefox) or - if you use the TikTok Windows app - by resetting it from Windows Settings.

If TikTok is eating your phone's storage, it's not a bug - it's the app silently caching every video you scroll past. A fresh install can hit 3+ GB in two days of normal scrolling. Here's the full clean-out, on phone and PC.

Why Your TikTok Cache Gets So Big

Every video you watch on the For You page gets cached so it loads instantly if you revisit it or scroll back. TikTok also caches profile pictures, sounds, drafts, and downloaded videos. Over a few weeks of normal use, this can easily climb past 5–10 GB.

Two things to know before you start:

• Clearing your cache will not reset your algorithm. Your watch history, likes, and recommendation data live on TikTok's servers, not in the cache.
• You will not lose your drafts as long as you only clear Cache and Downloaded videos, not the entire app data. (We'll flag this clearly below.)

How to Clear TikTok Cache on Phone (iPhone and Android)

There are three separate places TikTok hides cached data on mobile. To fully clean up, you need all three.

Step 1: Wipe Your Watch History (The Hidden One)

This is the trick most "clear cache" guides miss - and it's where the largest chunk of storage lives.

1. Open TikTok and tap the Search icon (top right of the For You page).
2. In the search bar, type a single period: . (if a period doesn't work, type a hashtag # instead). Tap Search.
3. A Watch History option appears in the results. Tap it.
4. Tap Select in the top-right corner.
5. Tap Select all, then Delete, and confirm.

This clears every video you've watched. As noted above, it does not affect your recommendations.

Step 2: Use TikTok's "Free Up Space" Tool

1. Go to your TikTok Profile.
2. Tap the three lines (☰) in the top-right corner.
3. Tap Settings and privacy.
4. Scroll down and tap Free up space.
5. You'll see your current cache and downloaded-video storage. Tap Clear on both:
   • Cache - safe to clear, no data loss.
   • Downloaded videos - removes videos you saved for offline viewing.

This usually frees up the biggest single chunk of space.

Step 3: Clear App Cache From Your Phone Settings

The in-app tool doesn't catch everything. To get the rest, go through your phone's system settings.

On Android:

1. Open phone Settings.
2. Tap Apps (or Apps & notifications).
3. Find and tap TikTok.
4. Tap Storage.
5. Tap Clear cache.
6. ⚠️ Do not tap "Clear data" unless you're ready to log back in and lose drafts. "Clear cache" is the safe option.

On iPhone: iOS doesn't expose a per-app cache button. Your only options are:

• The in-app Free up space tool above (Step 2), or
• Offload the app: Settings → General → iPhone Storage → TikTok → Offload App. This removes the app but keeps your account data. Reinstalling pulls a clean cache. Drafts saved only to the app cache will be lost - back them up first.

How to Clear TikTok Cache on PC

TikTok on desktop doesn't store data the same way as the mobile app, and there is no "Clear cache" button inside tiktok.com or TikTok Studio. You clear it through your browser instead.

Option 1: Clear TikTok's Cache for One Site Only (Recommended)

This wipes just TikTok's data without logging you out of every other site you use.

Chrome and Edge:

1. Go to tiktok.com and sign in.
2. Click the lock icon (or "tune" icon) to the left of the URL.
3. Click Site settings (Chrome) or Permissions for this site (Edge).
4. Find Cookies and site data and click Clear data, or scroll to the bottom of Site Settings and click Clear data.

Firefox:

1. Open Settings → Privacy & Security.
2. Scroll to Cookies and Site Data → click Manage Data.
3. Search for tiktok, select it, and click Remove Selected.

Option 2: Clear All Browser Cache (Faster but Wipes Everything)

Use the universal shortcut Ctrl + Shift + Delete on Windows (or Cmd + Shift + Delete on Mac) in any browser. Then:

• Time range: All time
• Check: Cached images and files (and Cookies, if you want a full clean)
• Click Clear data

This signs you out of every site, not just TikTok, so use Option 1 unless you actually want a full reset.

Option 3: Reset the TikTok Windows App

If you use the standalone TikTok Windows app (from the Microsoft Store), it has no in-app cache option. Reset it from Windows:

1. Open Settings → Apps → Installed apps.
2. Find TikTok in the list, click the three-dot menu → Advanced options.
3. Scroll to Reset and click it. Confirm.

⚠️ This wipes all local app data, including your sign-in. You'll need to log back in afterward.

TikTok LIVE Studio note: If you stream with the separate TikTok LIVE Studio broadcasting app (not the same as the regular TikTok app), its cache lives in %LocalAppData%\TikTok LIVE Studio. You can delete that folder manually while the app is closed.

How Much Space Will I Actually Recover?

Real numbers from typical users:

If your TikTok is hogging more than 10 GB and Step 2 doesn't clear most of it, the culprit is almost always downloaded videos and drafts you've forgotten about.

Will Clearing Cache Log Me Out or Reset My Algorithm?

This is the question that stops most people from doing it. Short answers:

The algorithm is stored on TikTok's servers and tied to your account, not your device. Wiping the cache changes nothing about what you see on the For You page.

How Often Should You Clear It?

If you're a regular TikTok user, once a month is plenty. If you're a creator with drafts and offline downloads, do Step 2 only (Free up space) every couple of weeks - it's the safest, fastest one and recovers the most space.

If your phone is constantly running out of storage, the real fix is often Step 1 (Watch History). TikTok's caching is aggressive, and that one bucket grows fastest.

Troubleshooting

"Watch History" doesn't appear when I search "."

• Update TikTok to the latest version. The Watch History feature rolled out gradually and older versions don't have it.
• Try typing # instead of .
• Make sure you're signed in - signed-out browsing has no history to clear.

"Free up space" shows 0 MB even though TikTok is huge in my phone settings

• The cache may have been cleared recently. The remaining storage is the app itself plus drafts. Go to Step 3 (phone Settings → Clear cache) for the leftovers.

My TikTok keeps re-filling cache instantly

• That's normal. Every time you scroll, new videos get cached. The goal of clearing isn't permanent - it's a periodic reset.

Clearing data deleted my drafts

• Drafts on TikTok are stored locally by default. If you cleared data (not cache), they're gone unless you'd uploaded them. To prevent this in the future, post drafts as "Only Me" to back them up to TikTok's servers before clearing data. See where to find TikTok drafts for a full breakdown.

The Bottom Line

To fully clear TikTok cache on phone, you need all three steps: Watch History → Free up space → phone Settings. The first one is the hidden trick that recovers the most space and the one most guides skip.

On PC, there's no in-app option - clear TikTok's browser data through your browser settings (use the site-specific method to avoid signing out of everything else), or reset the Windows app if you use it.

Key takeaways:

• Clearing cache does not reset your For You algorithm
• Cache lives in three separate places on mobile - all three need cleaning
• Desktop TikTok cache is just browser cache - no in-app button exists
• Always pick "Clear cache" over "Clear data" to keep your drafts and stay signed in
