Customize Your Brand Logo and Favicon in Cal ID
The Custom brand logo and favicon section replaces Cal ID branding with your own logo and browser icon.
- Log in to Cal ID.
- Click the Settings icon in the left sidebar.
- Open Custom Branding.
- Scroll to the bottom and switch Custom brand logo and favicon ON.

- Logo: click Upload logo and select a 600 × 400 px image.

- Favicon: click Upload favicon and select an icon file (under 1 MB).

- Click Update to apply.
- Booking page: your logo appears at the bottom of the booking interface, replacing the default branding.

- Browser tab: your favicon shows in the tab when a guest opens your booking link.

Use a transparent-background PNG for your logo so it looks natural in both Light and Dark mode.
