This reads your clip and reports — it does not re-encode it. Converting video in a browser means a very large download and a long wait, which is worse than the problem. Use your editor to change the shape, then check it here.
What the platform wants

Instagram accepts up to 20 minutes but says reels over three minutes are not recommended to new audiences, so three is the number that matters.
