Create a BIMI-compatible SVG logo

A normal website SVG is not automatically suitable for BIMI. The Portable/Secure profile removes features that could load remote content or behave interactively inside a mail client.

Required structure

The document must be valid XML with an SVG root. Set version="1.2" and baseProfile="tiny-ps", remove root x and y attributes, and include a title that identifies the brand.

  • No script or animation elements.
  • No external links, fonts, stylesheets, or resources.
  • No embedded raster <image> elements.
  • No interactive foreignObject or iframe content.

Design for unpredictable crops

Mailbox providers can render an indicator as a circle, rounded square, or other mask. Use a square viewBox, centre important artwork, and leave generous space around the edges.

  • A solid background is more reliable than transparency.
  • Outlined text is safer than relying on a font.
  • Keep contrast strong at small inbox sizes.

Gmail compatibility details

Google recommends absolute width and height values of at least 96 pixels, a file no larger than 32 KB, a centred mark, and a useful description element.
