WebinarNinja is a browser-based platform. There are no downloads required.

Any desktop or laptop computer, as well as smartphones or tablets, can be used to run or attend webinars.

You can create and run a separate webinar for testing with or without an attendee. This allows you to practice and familiarize yourself with the webinar studio.

Audio and video

When you enter the webinar studio for the first time, your browser will ask for permission to allow WebinarNinja to access your camera and microphone.

From here, you can check your microphone and camera to make sure WebinarNinja is picking them up. The microphone level should react to your voice, and the camera preview should show your camera stream.

Use earphones to prevent any computer audio from being picked up by your microphone and to avoid audio feedback.


A live webinar is optimized for the best experience based on the hosts’ network. It will automatically adjust for wired and wireless connections as well as for the host’s signal strength to our server.

Ensure a strong and stable internet connection. We recommend at least 1 Mbps with less than 0.5% packet loss to maintain a stable connection for your webinar.

You can test your connection from inside the webinar studio. Click the gear icon on the left sidebar then click Run Test. It will check your connection to our servers, as well as the quality of your audio and video stream.

Ideal results:

  • Supported: Yes

  • Quality: Good or Excellent

  • Packet Loss: less than 0.5%

  • Bitrate: more than 30 KB for audio, more than 1000 KB for video

  • Supported Resolution: 1280x720 @ 30 fps

If Supported: No, make sure your mic and camera are both connected and allowed for your browser to use.

Results other than the above may lead to some impairments in audio or video and some momentary disruptions.

The video resolution adjusts to your internet connection, in order to maintain connection: from 640x480 @ 30 fps up to 1280x720 @ 30 fps.

It is recommended that you broadcast from a device hardwired to the Internet, but if you can only connect through Wi-Fi, be sure that your signal is at 100%, and stay as close to your router as possible.

Close any programs running on your computer that you do not need for your webinar, to avoid their consuming needed bandwidth.

Should any of your attendees have any troubles seeing or hearing you on the webinar, send them this guide.
