Very long content creates denser codes. Keep strong foreground/background contrast and test the downloaded code before printing.
よくある質問
Is my content uploaded?
No. The QR image is generated in your browser and no content is sent to our servers.
Can I use a logo?
Yes. Add a local image and keep it small so the error-correction area remains scannable.
Which format should I download?
SVG stays sharp at any print size; PNG is convenient for documents and social posts.
