To ensure that the templates are on-brand, admins need to upload the brand logos under the 'Brand Kit' section. Refer to this article for a quick step-by-step process on how to upload brand logos.
However, the type and size of the logo being uploaded matter a lot either while using it for a template, a QR code or any other asset.
On Cliquify, you can upload both full and icon-only logos in .jpg, .jpeg .png, or .svg formats. Also, ensure that you upload all variations of the logo (horizontal, vertical and square) and a transparent logo which will enable you to use that on any background color, compliant to your brand, while creating a template.
