How to Format Your SVG Logo for BIMI
Strict BIMI requirements mean that only well-prepared SVG logos will display correctly—insecure or non-compliant files will fail validation, costing time and reducing brand visibility.
SVG Logo Requirements for BIMI
SVG Tiny Portable/Secure Format
- Use the Correct Format: Save your logo in SVG Tiny PS (Portable/Secure) format. Note that most design tools export SVG Tiny 1.2, but manual editing is required for full PS compliance.
- Set baseProfile Attribute: Update the
baseProfile
attribute in the SVG header to "tiny-ps" for proper compliance.
Square Dimensions & File Size
- Maintain Aspect Ratio and Size: Ensure the logo has a 1:1 aspect ratio (square) and is less than 32KB in size for reliable inbox rendering.
- Optimize Logo File: Use SVG editing or compression tools to reduce the file size while maintaining quality and compliance.
Clean, Simple Design
- Avoid Unsupported Features: Do not use gradients, transparency, animations, embedded bitmap images, external links, or scripts as these are disallowed and can cause display issues.
- Design for Consistency: Use a solid background color and center the logo to ensure consistent display within circular or square frames across different email clients.
Step-by-Step: Prepare a BIMI-Compliant SVG Logo
Export in Illustrator or Similar
- Create or Modify Logo: Use Adobe Illustrator or similar software to create or modify your logo.
- Export as SVG Tiny 1.2: Export the logo in SVG Tiny 1.2 format with “Preserve” options enabled for image location.
- Use Simple Filename: Save the file with a short, simple name using no spaces, uppercase letters, or special characters.
Manual Code Adjustments

baseProfile
value from "tiny" to "tiny-ps" and remove anyx

element directly under the<svg>
tag with fewer than 65 characters. - Check for Unsupported Elements: Verify the SVG does not contain forbidden elements such as
<script>
,<image>
,<animate>
, or any external file references.
Validation and Optimization
- Test with BIMI SVG Validators: Use online tools like the BIMI Group Validator to identify and fix errors in your SVG file.
- Optimize SVG File: Remove unnecessary metadata and compress the SVG using tools such as SVGOMG or SVGO to reduce file size.
- Upload Securely: Host the validated and optimized SVG file via HTTPS on the same domain as your BIMI DNS record for proper referencing.
