Designing for 18 px
- One face or symbol, thick outline, very few colors.
- Tell tiers apart by color (bronze, silver, gold), not by small details.
- Check the 18 px version at actual size before uploading.
Staying under 25 KB
Flat colors keep badges small. If a PNG is over, a palette PNG with 128 or 64 colors usually fixes it without visible change.
