Your artwork.
Scannable.

Before you upload

• Any photo works. The code is a square. Drop any image and crop it to a square right here — no editor needed.
• One clear subject. A face or a single object in the centre reads best — busy edges get lost.
• High contrast. Strong light-and-dark holds the pattern together and scans cleaner.
• At least 1000px. Bigger source = sharper 2048px master. PNG, JPEG, or WebP up to 10 MB.
