​Please read article below for specific image recommendations:

Go to your site settings and choose "branding" from the sidebar on the left to edit the logos and colours that appear in your site.

• This is the image that will be displayed in the header in your site. Read more about setting up your site

• Logo image should preferably have a transparent background for better results
• No margins around the logo
• Be at least 100px high for better results
• Be 300 pixels wide max
• Preferable filetype: PNG/SVG

💡 Pro tip: If you have your logo as an SVG file, use that instead – it will look crisp whatever size your display :)

Square logo

• Your square logo will be used in places where it better fits the format, such as for sharing and preview icons
• Should be a 1:1 image larger than 400px
• Preferable filetype: PNG/SVG

• Check the box beneath the uploader to use this image as your site's favicon icon too (that's the little image that appears in the toolbar of your browser)

• Do not have an overly long logo
• Logos should not include small or hard to read text

• Do not include small, hard to read text in a Square logo

💡 Pro tip: If you require help with your logos, reach out to your graphic designer or get in touch with us and we can make adjustments for you.
