How to Reduce Zoom Data Use

Zoom can be a real data hog, and it only makes things worse when you share Wi-Fi with multiple people. If you want to optimize your Zoom speeds, you really have these three options:

  1. Reduce your Zoom data with the tips we’re about to mention.
  2. Upgrade your internet service provider.
  3. Beg your kids (or roommates) to not stream Paw Patrol while you’re on a Zoom meeting.

Obviously, option number one is the ideal situation, so let’s try and figure that one out.

How much data does Zoom use?

Let’s get an idea of how much data you burn while using Zoom. Before we drop a ton of internet jargon on you in the tables below, feel free to familiarize yourself with our internet speeds guide.

Zoom data usage for a 1:1 meeting
High270 MB/hr.270 MB/hr.540 MB/hr.
720p540 MB/hr.540 MB/hr.1.08 GB/hr.
1080p810 MB/hr.810 MB/hr.1.62 GB/hr.

For a 1:1 Zoom meeting, you spend somewhere between 540 MB and 1.62 GB per hour, or somewhere between 9 MB and 27 MB per minute, depending upon the streaming quality.

Zoom data usage for a group call
High450 MB/hr.360 MB/hr.810 MB/hr.
720p675 MB/hr.675 MB/hr.1.35 GB/hr.
1080p1.2 GB/hr.1.2 GB/hr.2.4 GB/hr.

The more people you have in a Zoom call, the more data you’ll use up to run the meeting. Your data usage jumps up to somewhere between 810 MB and 2.4 GB per hour, or somewhere between 13.5 MB and 40 MB per minute.

What’s the difference between download and upload speeds?
Zoom uses your internet download speeds to stream what you see on a conference call, and uses upload speed to broadcast your stream to other people on the conference call.

Okay, so we just talked a lot about MBs and GBs, but let’s give some context as to what those data measurements really mean for you.

Data usage for common activitie
4K video streamingAmount of data used
4K video streaming5.85 GB/hr.
HD video streaming2.5 GB/hr.
SD video streaming0.7 GB/hr.

Now that we’ve got context for how much data Zoom uses, let’s try to dramatically lower your Zoom data usage.

Leave video off when you don’t need it.

The bulk of your internet upload speeds are dedicated to streaming your video to other folks on the conference call. If you turn off your video feed, then your Zoom data usage drops by at least 30% by our estimation. Plus, with your video feed off, you can do Zoom meetings in your pajamas completely guilt free!

How do I turn off my Zoom video?

Before you join a meeting, you should get a prompt asking you whether or not you want to turn on your video. It will look like this:

Join Zoom Without Video

You can click Join without Video and your video feed will be turned off at the get-go of the meeting.

If you already have started your camera in the meeting, but want to turn it off to conserve some of your data, you can just click the Stop Video button on the bottom right corner. It looks like this:

Turn off HD video.

Reducing your streaming quality can reduce the Zoom data you use by more than 60%. Besides, do you really need everyone’s faces on a  Zoom call in full high-definition? Personally, I would prefer people see me in a lower definition.

How to turn off HD video

First navigate to your Zoom settings. On the desktop Zoom client, you can find the gear icon for settings in the top right corner when you first open the app.

Once you get to Settings, click the Video tab on the left-hand side, and untoggle the box that says Enable HD. You can also apparently touch up your appearance here, too, but I can’t really tell if it’s helping.

By clicking on that box, the amount of data your Zoom requires should drop dramatically.

Don’t screen share longer than necessary.

Screen sharing takes up more data than just broadcasting a live video. If you want to pinch pennies with data, show what you need to show with your screen sharing, and then hop back to your normal camera.

Collaborative docs save more data than screen sharing.
You can always use a collaborative document (like a Google Doc) instead of screen sharing. People on the shared doc can see what everyone else contributes to the doc in real time.

Are your Zoom calls always glitchy?

If your Zoom calls look as fuzzy as 1980s basketball used to look on TV, then it might be time to consider upgrading your internet. Our internet expert Catherine says that Xfinity internet is currently the best internet provider out there.
