Branding what your customers see — Set your identity
Open Settings → Branding. Organisation name is used wherever there is no logo, in the footer of the emails you send your customers, and as the sender name on ticket replies — so it is worth setting even when you have a mark.
Logo takes a PNG, JPG, GIF or WebP up to 2 MB. It is displayed up to 44px tall on a form or a booking page, and smaller where space is tighter — in an email, on the help centre, in the chat window — so a wide lockup works far better than a square icon. SVG is refused: an SVG is a document that can carry script, and this image is rendered on pages RowFold serves to the public.
