Clear WeChat Cache on Mac

Clearing the WeChat cache removes the cached copies the app keeps, and it can save space from a data range of 1 GB – 20 GB. If the app offers a cache option, use that first, since it leaves your chat history alone. Work in the folder only if the app offers no option, and then remove only cache items.

WeChat cache folders you can clear

WeChat has no separate cache folder. Its folders hold settings and your own data, so there is nothing to clear safely by hand.

What the WeChat cache holds and when clearing helps

Specific to WeChat

The folder at ~/Library/Containers/com.tencent.xinWeChat holds the chat database, the media cache and received files together. Images, videos and files you receive build up there, which is why the folder can grow very large. Clearing helps when that folder has grown large and storage is short or the app feels slow. The chat database is your own data, so it is not something to clear.

What happens after you clear the WeChat cache

The app rebuilds its cache as you use it, so the first start afterwards will likely be slower. Chat history on this Mac is a local copy that is not restored automatically, so keep the chat database in place. Your account is tied to your phone, so check there whether you are still signed in. If the Mac asks you to sign in again, confirm it from your phone.
