WebinarJam: Why is my webinar fuzzy or blurry?

This Article is for


Unfortunately, when streaming live video on the internet, quality always becomes an issue.


User End

Most of the time, the culprit is on the individual user's end, with their specific computer settings, bandwidth and speed.  Your lighting, camera, processor speed will also affect the user experience on any webinar.
While technically WebinarJam only needs 1 mbps/2 mbps (up/down) this is at the lowest end of connectivity.  WebinarJam strongly recommends at least 2.6 up.   You can check your speed here: SpeedTest
Download speed is what enables your attendees to chat with you.  Upload speed is what enables your video to get to your attendees, so the higher the upload the faster and better your connection should be. 



Steps you can take

But there are some things you can do to make your webinar run a bit smoother.

  1. Better than Minimum Speeds: Test your internet speed with a service like SpeedTest.  We recommend at least 2mbps upload and 5mbps download.
  2. Wired Connection: Run your webinars from a hardwired internet connection instead of WiFi, if possible.
  3. Adjust: You may need to adjust the bandwidth / or definition settings in your Webinar Provider (see related articles below)
  4. Make certain your computer meets requirements. (Opens in a new window)
  5. Minimize Resources Used: Close out of all apps, programs, windows, tabs, music, or anything that isn't necessary to your webinar to free up as many of your computer's resources as possible. Applications like Google Drive, DropBox, Sugar Sync may automatically update and can use your internet resources.
  6. Clear: Clear your cache/cookies, log out of all Google properties, restart your machine and run your webinar from a fresh Chrome browser.

If you can advise you attendees to to do 5 and 6, that will also help their experience, however their internet speed can cause problems as well.



Is your presentation or screenshare fuzzy?

We strongly recommend uploading your slideshow to WebinarJam.

When you share your presentation or screen, it might seem like the larger the screen you share the easier it will be for your viewers to see... however a full screen display takes up a lot of resources and can appear pixelated and blurry for your viewers.

It may seem counter-intuitive, but the smaller screen you share the less fuzzy it will be.  This is why we recommend that you change webinars to presentations to browsed by individual window.

Change Definition Settings

If your internet speed is lower, you may want to change what definition displays. You can click the Camera icon, and choose from one of the following definition levels:

  • 1280 X 720 for HD / High Definition
  • 640 X 360 for SD /Standard Definition
  • 320 X 180 for LD / Low Definition
