Edge Add-ons extension logo: 300x300 recommended, 128x128 minimum

The extension logo in Edge's Partner Center listing is required for each language. Edge wants a 1:1 image, recommends 300x300 and sets 128x128 as the minimum. Those sizes are under GPT Image 2.5's pixel floor on Sume, so request 1024x1024 and downscale.

Edge's rules are from Microsoft Learn; Sume's from the Image API docs. Both read 2026-10-01.

What does Edge require?

Per the publishing page, the logo is an image with a 1:1 aspect ratio, 300x300 recommended and 128x128 minimum. One logo is needed per language, and a Duplicate option copies it to the other languages you have added.

What size should I request?

1024x1024 has 1,048,576 pixels and edges that are multiples of 16, so it passes (our arithmetic). Neither Edge size does: 300x300 is 90,000 pixels and 128x128 is 16,384.

What do I send?

Then resize to 300x300 in your own tool.

curl -X POST https://api.sume.com/v1/images \
  -H "Authorization: Bearer $SUME_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "model": "openai/gpt-image-2.5",
    "prompt": "Extension logo: simple orange compass mark on a solid white square, flat vector look, no text",
    "image_size": "1024x1024",
    "output_format": "png"
  }'

Do I need a different logo per language?

Edge requires one per language, but the Duplicate option copies one image across them, so a single file can do.
