Frequently asked questions

Is it really free?

Yes. There's no paid plan, no trial and no watermark on what you download. What you make here is yours to print and use wherever you like.

Do I need to sign up?

No. We don't ask for an email, password or card. Open it, make your QR or review link, and download it.

Do my QR codes expire?

No. They're static codes: what you type goes inside the code itself, not through a link of ours. They work as long as your page, number or network exists.

What do you do with what I type?

QR codes are made in your browser and we don't store what you type. For the review link we look up the Google Maps link you paste, only to find your business.

Is this made by Google?

No. Business Tools is made by Carbono and isn't affiliated with Google. The review link opens Google's official review form for your business.

Can I take it to a print shop?

Yes. Review cards download as PNG or as a PDF with crop marks, and QR codes as PNG, SVG or PDF. Any print or copy shop can print them.
