Resize Any Video to 9:16 for Social Media
Widescreen video doesn't fit a phone screen. Clipus reframes your 16:9 footage into clean 9:16 vertical clips sized for TikTok, YouTube Shorts, and Instagram Reels — with the trim, captions, and export handled in the same app.

How do I convert a horizontal video to vertical?
Open your clip in the Clipus editor, set the in and out points, and choose the vertical reframe. Clipus crops the 16:9 frame into a 9:16 composition, keeping the subject in view, then renders the result locally with ffmpeg. Add animated captions in the same pass, and the exported file is ready to upload — no second tool, no re-encode chain.
- 9:16 vertical output for TikTok, Shorts, and Reels
- Trim in/out points before reframing
- Captions burned in during the same render
- Local ffmpeg rendering — fast, private, no upload queue
Why 9:16 instead of just cropping square?
Vertical 9:16 is the native aspect ratio of every major short-form feed. TikTok, YouTube Shorts, and Instagram Reels all display 9:16 full-screen; square or letterboxed video shows smaller, with wasted space, and typically underperforms. Exporting true 9:16 means your clip fills the viewer's entire screen.
Does resizing reduce quality?
Clipus renders from your source file in a single ffmpeg pass — cut, reframe, and captions together — instead of re-encoding multiple times through different tools. One encode means less generation loss and a sharper final clip.
Built on: FFmpeg (open-source video renderer)
Frequently Asked Questions
What aspect ratio should I use for TikTok and Shorts?
9:16 (1080×1920) is the native full-screen format for TikTok, YouTube Shorts, and Instagram Reels. Clipus exports vertical 9:16 clips by default.
Can I resize videos without uploading them?
Yes. Clipus is a desktop app — reframing and rendering run locally on your computer, so your footage is never uploaded to any server.
Can I keep the original aspect ratio?
The editor lets you control the trim and framing of each clip before export, so you decide how each clip is composed.
