Why DemoZoom?
Cinematic zoom, where you want it
After recording, click to drop a zoom point anywhere — DemoZoom renders a smooth, cinematic camera move to that spot and exports an MP4. No timeline, no editing software.
Instant — no cloud, no wait
No upload, no server render queue. Everything runs locally on WebCodecs/WebGPU, so your MP4 is ready the moment you stop. Your recording never leaves your device.
Screen Studio quality, on Windows
The expensive Mac-app look — cinematic zoom, depth, polished background — in your browser on Windows, nothing to install. Completely free, no sign-up.

Frequently Asked Questions
How do I add zoom to a screen recording?+
Record your screen, then click 'Add Zoom Point' and click where you want the camera to zoom in. DemoZoom renders a smooth, cinematic zoom there and exports an MP4 — no video-editing software needed.

Exports carry a small demozoom.app watermark by default, but you can remove it for free with one click before exporting — no payment, no account. So a watermark-free MP4 costs nothing.

No. Capture, editing and export all run in your browser — your video never leaves your device. That's also why export is instant: no upload, no server render wait.
