HOW TO CREATE LOGO SIZES
- Start with a high-resolution square master (at least 600×600, ideally 1200×1200)
- Use Squoosh (free, browser-based) to resize and export each size as PNG
- Or use ImageMagick:
convert logo.png -resize 32x32 logo_32.png
- Host all sizes on your CDN and enter each URL above
- The 600×600 square logo is the most important, start with that one
- Use PNG format with transparency for best receiver compatibility
