How to Clear Slack Cache on Any Device

Slack is a popular communication and collaboration tool used by teams and organizations around the world. It allows you to chat, share files, and collaborate with coworkers in dedicated channels and direct messages.

Over time, Slack can build up a cache of data that takes up storage space and slows down performance. Clearing this cache can help free up storage, speed up Slack, and fix other issues you may experience. The steps to clear cache differ slightly depending on what device you use Slack on.

Clearing Cache on Desktop

Slack is available as a desktop app for Windows and Mac computers. Here’s how to clear cache in the desktop app:


  1. Close Slack if it’s open.
  2. Open the Windows search bar and type “%AppData%”. Hit enter.
  3. Open the Slack folder.
  4. Delete the following folders:
    • Cache
    • Code Cache
    • GPUCache
    • IndexedDB
    • Local Storage
    • Service Worker
  5. Open Slack again. The cache has now been cleared.


  1. Close Slack if it’s open.
  2. In Finder, hit Command+Shift+G to open the ‘Go to Folder’ window.
  3. Type in “/Users/YOURUSERNAME/Library/Application Support/Slack” with your username instead of “YOURUSERNAME”. Hit enter.
  4. Delete the Cache, Code Cache, GPUCache, IndexedDB, Local Storage, and Service Worker folders.
  5. Open Slack again. The cache has been cleared.

Clearing cache on desktop removes temporary files, empties stored profile images, and ensures Slack runs smoothly.

Clearing Cache on Mobile

Slack is available as mobile apps for both iOS and Android. Here’s how to clear stored cache on mobile:

iPhone and iPad

  1. Open the iOS Settings app.
  2. Select General.
  3. Choose iPhone Storage.
  4. Select Slack from the list of apps.
  5. Tap Offload App to temporarily delete Slack and clear its cache.
  6. Reinstall Slack from the App Store to get a clean slate.


  1. Open your device’s Settings app.
  2. Tap Apps.
  3. Select Slack.
  4. Tap Storage.
  5. Tap Clear Cache and Clear Data to wipe the Slack app cache.
  6. Force stop the Slack app for the changes to take effect.

Clearing the cache and data on mobile removes temporary files, logins, settings and frees up storage space used by Slack.

Clearing Cache on Web

Slack is used directly in web browsers like Chrome and Firefox. Here’s how to clear cache when using the Slack web app:


  1. Click the 3 vertical dots in the top right corner.
  2. Hover over More Tools.
  3. Select Clear Browsing Data.
  4. Choose the time range for data you want to clear.
  5. Check the boxes for Cookies, Cache, and Site Data.
  6. Click Clear Data.


  1. Click the 3 horizontal lines in the top right corner.
  2. Select Settings.
  3. Scroll down to Privacy & Security in the left menu.
  4. Click on Cookies and Site Data.
  5. Click Clear Data.
  6. Select Cache and Cookies then click Clear.

Clearing browser cache removes stored Slack login sessions, images, site data and frees up disk space.

Why Clear Cache?

Clearing your Slack cache provides a few key benefits:

  • Frees up storage space on your device taken up by temporary files.
  • Speeds up performance by removing bloated cached files.
  • Fixes odd issues caused by corrupt cache files.
  • Logs you out of Slack on all devices to enhance security.
  • Provides a clean slate if experiencing bugs or glitches.
  • Ensures you have the latest versions of all files.

It’s a good idea to periodically clear cache on Slack, about once per month, to optimize performance. Clearing cache only takes a minute but provides long-term improvements.

Troubleshooting Slack Issues

If clearing cache doesn’t resolve your problems, here are some other tips:

  • Update to the latest version of Slack. Old versions may have bugs.
  • Reinstall Slack if clearing cache doesn’t work.
  • Check internet connectivity. Connection issues can disrupt Slack.
  • Make sure your system software is updated on all devices.
  • Try logging out and back into Slack to refresh sessions.
  • Contact Slack customer support if problems persist.

Clearing cache is one of the easiest fixes for Slackissues. But updating software, reinstalling Slack, checking connectivity, and logging out can also help troubleshoot more difficult problems.


Clearing your Slack cache is simple and provides many benefits – it frees up storage space, speeds up performance, resolves odd issues, enhances security, and gives you a fresh start. Just delete the Cache, IndexedDB, Local Storage and Service Worker folders on desktop or mobile. For web, clear browsing data and website cookies. Remember to clear cache every month or so for optimal Slack performance.
