Do I need to download or install any software in order to use Spreed?

No, you don’t need to install or download software to hold a Spreed meeting. For screen sharing, you need to install our screen sharing plugin. If you use Firefox, even that is not necessary.


Low Bandwidth

The reason for a bad connection is not necessarily low bandwidth, but it should not be underestimated. The basic operating principle of WebRTC is peer-to-peer. This means that all participants connect directly through the browser: the more participants are in a session, the more bandwidth is necessary.

To improve this, a STUN/TURN server can be used, which not only amplifies the signal but also distributes the media signal to other participants. This reduces the required bandwidth of each participant and provides more stable connections.

Problems with Firewall, NAT, Quality of Service

As long as a WebRTC connection is running within a local network (within the company), the connection is usually possible without any problems. However, if the media signal is transmitted to or received from the Internet, a number of problems could arise quickly. An appropriately configured firewall can even prevent connections from being established or individual data packets from being lost on their way to their destination.

Behind a NAT-based network, a connection termination based on the technology alone can cause problems, since a direct connection of the participants is only possible if the infrastructure allows it.

The Quality of Service also plays an important role, especially for streaming data. This procedure prioritizes corresponding data packets differently than, for example, normal Internet surfing.

Make sure that your network/router is set up accordingly and prepared for WebRTC. A STUN/TURN server can also help here to counteract infrastructural problems.

My internet connection is too slow. What can I do?

Please make sure that other video conferencing applications are closed (like WhatsApp, Skype, ICQ, Facebook etc.) and use a cable bound VDSL internet connection. WiFi / EDGE / 3G connections may be volatile depending on your regional service provider or if you are too far away from the next WiFi router. Cable bound internet connections are more stable and the better choice for video calls. Check our WebRTC Troubleshooter to find out what could be causing the issue.

How do I activate WebRTC in my browser?

WebRTC is activated in your browser by default. However, it is possible that you have inadvertently or intentionally deactivated this function.

How to re-enable WebRTC in Firefox:

  1. Type about:config in the address bar.

  2. Click on the displayed button Accept the Risk and Continue.

About:config Firefox
  1. Enter media.peerconnection.enabled in the search bar.

  1. Double-click if necessary to change the value to ‘true’.

Plugins can prevent WebRTC

Browser plugins can be useful and extend the range of functions. However, especially with security plugins, this can have undesirable consequences such as WebRTC Control or Disable WebRTC. Check the installed plugins and try to disable or delete them if necessary.

Meeting Organisation

What can I do when participants haven’t received email invitations?

Spreed is sending invitation emails using a registered mail server. In rare cases, those automatic generated emails are rejected by the receiver’s mail server or spam filters.

Possible solutions:

  1. Ask your participant to check their spam folder or to update their spam filter settings

  2. Ask your participant to add Spreed to their secure sender list

  3. If this doesn’t help, send the person the meeting ID and PIN manually.

What happens to files and presentations after the meeting has ended?

You can still access them. Click on the Calendar icon, then click on the button All on the left side to get an overview of all your meetings. If you now go to the Past meetings section, you will find all of your past meetings including their files/presentations. You can share them with others or download them to your computer.

Audio & Video

I can’t hear anything with my headset, can’t see other participants via video conference. What can I do?

Please join the call and check the Settings icon in the lower right-hand corner and make sure that the right device is selected. Also check your system settings to make sure the devices have been installed properly.

There is echo in my call. What can I do?

Please use a headset and make sure the right audio device is selected. Ask the moderator to mute one participant after another to find out who is causing the echo.

In general, to prevent echo, we recommend using a headset. If you don’t have a headset, you could dial in over your phone (see Dial-in). Spreed offers several local dial-in numbers.

The volume is too high or too low. What can I do?

Check the sound settings of your notebook/PC and try different settings.

I can’t see any webcam video of other participants or others can’t see me, what can I do?

Please try these steps:

  1. Close the browser window and rejoin the meeting.

  2. If this doesn’t help, try a different web browser.

  3. If your own video is not transmitted, check the connections of your USB camera.

  4. Close all other video conferencing software.

If this doesn’t help, please get in touch with us. We’re happy to help!


Windows 10: Please check data security settings in your system settings, you have to enable camera/microphone access.

How many webcam videos can be shown simultaneously?

We recommend to transmit up to 8 webcam videos at the same time, but there is no hard limit.

Screen Sharing

I can’t share my screen with Firefox, what can I do?

When you are in a meeting and click on the screen sharing icon, Firefox asks you if you will allow Spreed to share your screen. If you accidentally deny it and you’ve checked the box “Remember this decision”, Firefox blocks this feature and doesn’t ask you about it anymore.

You can solve it by clicking on the crossed out screen sharing icon in the address bar of your browser. To reset the permissions, click on the little x icon next to it.

Change permissions

You can now try again to share your screen by clicking on the screen sharing icon  in the main menu next to the microphone and camera buttons. A popup will ask you if you’d like to allow Spreed to share your screen, now you click on “Allow”. Your screen will be transmitted to the other attendees.

Telephone Conferencing

Can I dial-in with my phone?

Yes, you can use several dial-in phone numbers we provide you with to dial in with your (mobile) phone.


  1. Call the number you have received with your email invitation or, if you’ve already joined the meeting with your browser, you can find the number when you click on the i icon in the lower menu.

  2. After a connection has been established, you enter the meeting ID (you can find it in your invitation) followed by #, then your PIN number followed by #.


If you dial-in with your mobile phone, simply click on the mobile link we provide in the invitation. It will automatically submit your login details and you don’t have to enter anything by hand.

Mobile Apps

Can I join the meeting with my smartphone or tablet?

You can join a conference call with your mobile phone by using the mobile link provided in your invitation.

We are currently working on mobile apps for Android and iOS. They will be available soon.


Is Spreed secure?

All media streams in online meetings are securely encrypted. Plugins are not required to use Spreed. Encryption is enforced on all aspects of establishing and maintaining a connection. It makes it impossible for someone to gain access to the contents of a communication stream. A connection can only be established with secure HTTPS protocols. You can create an additional meeting room PIN number, so that uninvited guests cannot join the meeting. When you share files via URL, you can set a password. Under Settings -> Security you can configure two-factor authentication.
