Your iPhone is your best camera.
Now it's your Mac's 4K webcam.

OBS 4K streams your iPhone camera to your Mac over USB or WiFi using H.265 hardware encoding, and shows up as a camera in Zoom, Teams, OBS Studio and other apps that accept virtual cameras. Free at 720p; Pro unlocks 1080p, 4K and 60 fps.

The camera in your pocket beats any webcam you can buy.

Dedicated webcams top out at mediocre sensors and plastic lenses. Your iPhone already has the best camera system you own — OBS 4K unlocks it for your Mac with a zero-copy, hardware-accelerated pipeline.

FAQ

Questions, answered.

Can I use my iPhone as a webcam for my Mac?

Yes. OBS 4K turns your iPhone into a professional 4K webcam for your Mac. Install the iPhone app and the Mac companion, and your iPhone appears as a virtual camera in Zoom, Teams, OBS Studio, and any app that supports virtual cameras — over USB or WiFi.

How is this different from Apple's Continuity Camera?

Continuity Camera is free, built into macOS and iOS, and works wired or wirelessly, so try it first. It tops out at 1920x1440. OBS 4K Pro adds 4K, and OBS 4K lets you pick resolution and lens and includes a screen curtain mode for long sessions.

Does it work with Zoom, Teams and OBS Studio?

Yes. The Mac companion installs a system virtual camera, so OBS 4K shows up as a webcam in Zoom, Microsoft Teams, Google Meet, OBS Studio, and every other app that accepts virtual cameras.

USB or WiFi — which should I use?

Both work. USB charges your iPhone while you stream and doesn't depend on your WiFi, which suits long calls and recording. WiFi lets you place the camera anywhere. OBS 4K finds your Mac automatically via Bonjour.

Is my video private?

Completely. Your camera stream travels only between your iPhone and your Mac — over your local network or USB cable. No video data ever touches the internet. Read the full privacy policy.

Look better on every call.
