You can customize the logo users see in the top left corner of the Zulip app. For best results:

• The logo should be a wide rectangle image with an 8:1 width to height ratio. It will be displayed at 200×25 pixels, or more on high-resolution displays.

• Make sure your logo has a transparent background, and trim any bordering whitespace.

To upload a logo:

{start_tabs}

{settings_tab|organization-profile}

1. Under Organization logo, upload a new logo.

{end_tabs}

Make sure to test the logo in both light theme and dark theme.
