Resize video for Instagram Reels
Reels demand tall 9:16 video and punish everything else with ugly auto-crops or shrunken letterboxes. Take control instead: drop any clip below with 9:16 pre-selected, then choose your strategy — cover-crop fills the whole phone screen (sides get trimmed), letterbox keeps every pixel with classy bars. Pick an output width, download, and post. The same 9:16 file works for TikTok and YouTube Shorts too.
How to reframe for Reels
- 1Drop your video on the resizer above. The 9:16 shape is already selected.
- 2Choose cover or letterbox Cover fills the screen by trimming sides; letterbox keeps everything with bars top and bottom.
- 3Pick a width and download. 1080px wide is the Reels sweet spot — crisp without a bloated file.
Reels that look native
Cover for action, bars for text
Full-bleed cover crops suit movement; if captions or faces sit near the edges, letterbox keeps them safe.
Keep key content centered
The center survives every platform's UI overlays (usernames, like buttons) — that's where faces and text belong.
One file, three apps
A 9:16 MP4 posts natively to Reels, TikTok, and Shorts — make it once, ship it thrice.
Frequently asked questions
What size should Reels be?
1080×1920 (9:16) is the native Reels canvas. This tool outputs exactly that when you pick 9:16 at 1080px wide.
Will reframing crop my video?
Only in cover mode, which trims sides to fill the phone screen. Choose letterbox (fit) to keep every pixel with bars instead.
Can I post the result to TikTok too?
Yes — TikTok and YouTube Shorts use the same 9:16 canvas, so one export serves all three.
Are my videos uploaded?
No. Resizing runs 100% in your browser.
