Short-form video is the fastest-growing content format on the internet. TikTok, Instagram Reels, and YouTube Shorts together have over 2 billion daily active users. But creating content for these platforms requires specific video formats, aspect ratios, and export settings — and most desktop editors are overkill for a 60-second clip. You can now cut, crop, and export vertical video directly in your browser, completely free, in under 2 minutes.
Why Short-Form Video Needs Special Formatting
Each platform has a specific preferred format:
- TikTok: 9:16 vertical, 1080×1920px, MP4, up to 10 minutes
- Instagram Reels: 9:16 vertical, 1080×1920px, MP4, up to 90 seconds
- YouTube Shorts: 9:16 vertical, 1080×1920px, MP4, under 60 seconds
- Instagram Square: 1:1 (1080×1080px) for feed posts
- YouTube Standard: 16:9 landscape for regular videos
All three major short-form platforms use the same 9:16 format. Cut once, export for all three.

What the 9:16 Aspect Ratio Actually Means
The 9:16 ratio means the video is taller than it is wide — the natural orientation of a phone held vertically. If your original video is 16:9 (horizontal, like most camera recordings), you have two options:
- Crop: zoom into the center of the horizontal video to fill the vertical frame. Works well if your subject is centered.
- Blur fill: keep the full horizontal video but add a blurred version of itself as the background to fill the vertical space. This looks professional and keeps all original content visible.
The blur fill option is the most popular approach for repurposing horizontal YouTube videos into Shorts/Reels content.
Editing Tips for More Views
- Hook viewers in the first 2 seconds — start with action, not a title card
- Keep Shorts under 60 seconds for maximum distribution on YouTube
- Add captions — 85% of short-form video is watched without sound

- Use jump cuts every 3–5 seconds to maintain energy
