Appearance
Your logo on the preferences panel
Upload a logo in the banner designer and it appears at the top of the preferences panel, left of the title, on every variant of that panel the widget draws: the classic cookie settings, the IAB TCF second layer and the US opt-out dialog. It never appears on the first notice, on purpose: that notice is a decision to read, and a logo there competes with it.
Available on the Pro plan and above.
Uploading
In the designer, open Style and drop a file into the Logo box, or click it to choose one. Accepted files: PNG (preferred for transparency), SVG (preferred for crisp scaling) and JPEG, up to 1 MB and 4000 by 4000 pixels. The file is checked and optimised on our side; SVGs are sanitised, so scripts, external references and animation are removed.
The preview redraws with the logo as soon as it is processed. Like every other Style setting, the logo is saved with the draft and reaches your visitors when you publish. Remove it with Remove logo and publish again to take it down.
Size
There are no size controls in this release. The logo is drawn 32 pixels high and at most 160 pixels wide, scaled to fit with its proportions kept; on narrow screens 24 by 120. A logo with a lot of empty space around it will look small - crop it before uploading.
Content Security Policy
The logo is served from cdn.cookiewave.com, the same host the widget itself loads from, but as an image. If your site sends a Content-Security-Policy header, that host has to be allowed for images as well:
img-src 'self' https://cdn.cookiewave.com;Without it the browser blocks the image silently and the panel shows no logo.
