How to make a video for Instagram Reels, TikTok and Shorts
Short-form video lives in a 9:16 vertical frame with bold captions and a strong hook. You do not need a desktop editor to get there — these browser tools cover the whole workflow, on any device.
Reframe to vertical 9:16
Reels, TikTok and Shorts all use a tall 9:16 frame. Crop a landscape clip to vertical so it fills the screen instead of sitting in a small letterboxed strip.
Keep a landscape shot whole with a blurred background
If cropping would cut off something important, fit the full landscape frame onto a vertical canvas with a soft blurred background — a look you see all over Reels and TikTok.
Add captions so it works on mute
Most feeds autoplay without sound, so on-screen text is what stops the scroll. Generate captions automatically with on-device AI, or add a punchy title yourself.
Drop in a music track
A trending or background track sets the mood and improves retention. Add your own audio over the clip before you export.
