Vertical screen recording
that stays readable.
Desktop UI in a 9:16 frame is unreadable — unless the camera zooms. Record your screen, click where the action is, and export a vertical MP4 where the UI actually fills the phone screen. Free, in the browser, nothing uploaded.
Make a vertical recording →The Shorts preset
One click sets everything a short needs: 9:16 output, a polished background behind the letterboxed recording, and 1080p. Then place two or three zoom points on the moments you're narrating — the cinematic push-in is what makes a desktop demo watchable on a phone.
- Record your screen (or import an existing video).
- Pick the 📱 Shorts preset — or choose 9:16 / 1:1 manually.
- Add zooms where the viewer should look.
- Export MP4 — rendered locally, ready to upload.
No re-editing in CapCut
The usual flow — record 16:9, drop it into a phone editor, crop, pan, export, lose quality — becomes one step. DemoZoom renders the vertical frame directly: your zooms drive the crop, so nothing important ever sits outside the 9:16 window.
FAQ
How do I record my screen in vertical 9:16 for Shorts or TikTok?
Record normally in DemoZoom (or import a recording), then pick the 9:16 output shape — or just click the Shorts preset. The export is rendered as a vertical MP4 with your recording letterboxed on a styled background.
Won't a desktop recording look tiny in a vertical video?
That's what the zoom is for. Drop zoom points on the moments that matter and the camera pushes into that part of the UI — text stays readable on a phone screen instead of shrinking the whole desktop into a strip.
Can I also export square 1:1?
Yes — output shapes are 16:9, vertical 9:16 and square 1:1. Square works well for LinkedIn and X feeds.
Is it really free? Is anything uploaded?
Completely free, no sign-up, and nothing is uploaded — recording, editing and the vertical export all run locally in your browser via WebCodecs.
