WeChat is an essential communication tool for millions of users, but over time, it can accumulate a massive amount of data, including photos, videos, voice messages, files, stickers, and caches. This often leads to WeChat occupying several gigabytes of storage on an iPhone, slowing down the device and affecting system updates, app installations, and daily performance.
If you're wondering how to manage WeChat storage on iPhone effectively, this guide provides four practical and detailed methods to help you reduce WeChat storage and free up valuable space.

In the WeChat app, you can clear the app cache or manage individual chat histories to delete large media files and free up space. This is the most basic and convenient way to do it.
Here is how to manage WeChat storage on iPhone in the WeChat app:
Step 1. Open WeChat on your iPhone.
Step 2. Tap "Me" at the bottom-right corner.
Step 3. Go to "Settings" > "General" > "Storage".
To clear WeChat cache on your iPhone: Locate the "Cache" section, where you'll see its size. Next, tap the "Clear" button and confirm by tapping "OK" in the pop-up window. The cache will then be cleared, without affecting your messages or media.
To manage media files (photos, videos, etc.) from your chats: Tap the "Manage" button next to "Chat Histories". Select the chats containing the files you want to remove, then tap the "three dots" (...) in the top-right corner. Tap "Clear" after selecting specific media files or choose "Select All" to remove everything.

If you don't mind deleting some content, removing chat history is one of the most straightforward methods.
Here is how to delete WeChat messages on your iPhone:
Step 1. Open WeChat on your iPhone.
Step 2. In the main chat interface, find the chat you want to clear.
Step 3. Long-press on the chat bubble.
Step 4. Tap "Delete Chat" or enter the chat, then tap the "..." in the top-right corner and select "Clear Chat History".
Step 5. Confirm the action.

If your WeChat is taking up a large amount of space (such as 10GB, 20GB, or more), but clearing the cache and chat history doesn't make much difference, it's likely due to the accumulation of hidden files and historical data that the system cannot identify. These hidden files cannot be cleared through WeChat's own cleaning tools. In this case, uninstalling and reinstalling WeChat is the most thorough method, as it will delete all cache and leftover files, restoring the app to a clean state.
Here is how to free up WeChat storage on iPhone via reinstalling the app:
Step 1. Delete the WeChat App from your iPhone.
Long-press the "WeChat icon" and then tap "Delete App", or go to "Settings" > "General" > "iPhone Storage" > "WeChat" > "Delete App".

Step 2. Reinstall from the App Store on your iPhone.
Open App Store, search for WeChat, and then tap "Download".
