How do I adjust the image quality of 1:1 video calls?

The image quality of video calls depends on the available bandwidth and the settings of your call partner. In case of a poor network connection, the image quality is automatically lowered.

The preferred image quality can be adjusted in the Threema settings under “Secure calls > Preferred image quality” (Android) or “Threema Calls > Preferred Image Quality” (iOS). The following options are available:

• Balanced (Recommended): High image quality in Wi-Fi, reduced data consumption in the mobile network
• Low Data Consumption: Reduced image quality for lower data consumption
• Maximum Quality: Warning: This setting can cause considerable data consumption, also in the mobile network!

If you and your call partner prefer a different image quality, the lower quality will be used. If, for example, you have set “Maximum Quality” as preferred image quality, this image quality will only be used if your call partner has also set Maximum Quality as preferred image quality.
