Questions People Ask
Honest answers about how this works.
What image format is best for the emblem?
Short answer: We recommend using a PNG with a transparent background. This allows your logo or symbol to sit naturally on top of the flag's colored stripes.
Can I really make a square flag?
Great question. The current tool uses a standard 3:2 flag aspect ratio, which is the most common for national and decorative flags.
