Instagram is notorious for accumulating large amounts of cached data. The app aggressively caches videos and stories to provide smooth browsing — consuming 500 MB to 2 GB of your storage in temporary files.
What Instagram Stores on Your Phone
- Image and video cache from every post and story you've viewed
- Reels cache — high-quality videos that use the most space
- Downloaded Reels audio and video
- App data: your login, DMs, settings, drafts, and saved posts
What You Can Safely Delete
Cache is entirely safe to delete. Your Instagram account, photos, messages, and saved posts are on Instagram's servers and won't be affected. Do NOT clear App Data unless you want to completely reset Instagram — it will log you out and delete local drafts.
Safe to Delete: Cache only. Think Twice: App Data (deletes drafts and logs you out).
How to Clear Instagram Cache
- Open Settings → Apps
- Find Instagram and tap it
- Tap Storage → Clear Cache

Reduce Instagram Cache Going Forward
