Fix 6. Verify Your File Size and Format

Trying to upload content that is too large will cause the processing bar to freeze indefinitely. Instagram requires specific media formats, generally favoring standard JPEG images and MP4 videos.

For videos, ensure your file uses the H.264 codec and AAC audio. If you are uploading a Reel or a long video, the maximum file size is 650MB for videos under 10 minutes, and up to 3.6GB for videos up to 60 minutes.

If your video was shot in Apple's ProRes format or at a massive 4K resolution, you will likely need to use a third-party video compression app to shrink the file before Instagram will accept it.

Fix 7. Offload the Instagram Cache

When a simple restart doesn't work, corrupted temporary cache data might be the culprit. Offloading the app clears out this hidden junk data without deleting your login information or personal settings.

  • Step 1. Navigate to your iPhone's Settings app, tap on "General", and then select "iPhone Storage".
  • Step 2. Scroll down the list of applications until you find Instagram, and tap on it to open the app's specific storage menu.
  • Step 3. Tap the blue "Offload App" button and confirm your choice. Once it finishes, tap "Reinstall App" to put it back on your home screen.
