Free Google review QR code generator

What is a Google review QR code?

A Google review QR code is a square barcode that opens your Google review form when a customer scans it with a phone camera. It removes every step between a happy customer and a review, which is why it works well on paper that a customer already holds, such as an invoice.

How do I make a Google review QR code?

1. Get your review link with our review link generator, or copy it from your Business Profile.
2. Paste the link or your Place ID into the tool above and add your company name.
3. Press the button and check the preview card.
4. Download the PNG card for print, or the SVG if you need a sticker or sign.
5. Scan the code with two different phones before you print anything.

Where should a contractor put a review QR code?

Put the code wherever a customer is already looking at something from you, right after the job. The best placements are the ones that match the moment the customer feels most satisfied.

Placement	Why it works	File to use
Invoice or receipt	Customer holds it right after the work	PNG card or SVG
Estimate or proposal	Reaches customers who have seen your work before	SVG
Door hanger or leave-behind card	Reaches customers who were not home	PNG card
Fridge magnet	Stays visible for the next service call	SVG
Truck or van sticker	Neighbors see it when you park on the street	SVG
Yard sign after a job	Reaches neighbors who see the work	SVG (check local sign rules)
Website thank-you page	Customers who book online	Use the link, not the code
Email signature	Every email thread	Use the link, not the code

How big should a review QR code be?

Print the code at least about 1 inch (2.5 cm) wide for close-up use such as invoices, and larger for anything scanned from a distance. A common rule of thumb in QR code guidance is that the scanning distance should be about ten times the code width, so a code scanned from 3 feet away should be about 3.5 inches wide. This is a rule of thumb, not a standard, so always test the printed result.

Where it is scanned	Typical distance	Suggested minimum width
Invoice or card in hand	About 1 foot	1 inch (2.5 cm)
Door hanger	1 to 2 feet	1.5 inches (4 cm)
Yard sign	About 3 feet	3.5 inches (9 cm)
Van side	5 to 10 feet	6 inches (15 cm) or more

The sizes above apply the ten-to-one rule of thumb and are our estimates. Your own phone test overrules the table.

What makes a QR code scan reliably?

• High contrast: dark code on a light background. Do not invert colors or use pale ink.
• Quiet zone: keep a clear margin around the code, about four modules wide. The PNG card and SVG from this tool include one.
• Flat, matte surface: glare and curved surfaces make scanning harder.
• No logo over the code: covering part of it can cause scan failures.
• Short link: shorter data makes a simpler code that scans from further away.

Should I use the PNG card or the SVG file?

Use the PNG for ready-made print pieces and the SVG when you want to place the code in your own design or enlarge it. A PNG is a fixed-size image, so enlarging it too far makes it blurry. An SVG is vector art that stays sharp at any size, which suits van stickers and signs.

How do I test my QR code before printing?

Scan the code on screen, then scan a test print, using two different phones if you can. The review form should open with your company name. Test again after printing a full batch, and test a sample of each print run, because ink and paper change results.

Why is my QR code not scanning?

Problem	Likely cause	Fix
Camera will not focus	Code too small for the distance	Print larger
Nothing happens	Low contrast or glossy glare	Use dark ink on light paper with a matte finish
Wrong page opens	Wrong link or Place ID entered	Create the code again with the correct link
Opens but no review form	Customer not signed in to Google	Ask them to sign in and try again

Does a QR code work forever?

The code stores your review link directly, so it keeps working as long as that link works. It is a static code, so there is no subscription and no third-party redirect that can expire. If your Place ID changes or you move to a new profile, create a new code. Several locations need one code each.

What does Google allow when asking for reviews?

Google allows you to share a review link or QR code and ask customers for reviews. Its policy bans offering incentives such as discounts or gifts for reviews, asking only happy customers, and reviews from employees. Do not put wording like "Leave a 5-star review for 10% off" on your card. The tool's card says "Enjoyed our work?", which asks for a review without asking for a rating.

Do review QR codes help local rankings?

A QR code does not rank you by itself. It makes asking easier, and Google says more reviews and positive ratings can help local ranking, which is mainly based on relevance, distance and prominence. Pair it with a complete profile and strong service pages, as explained in our local SEO for contractors guide, and use the review calculator to set a target.

Frequently asked questions

Is the QR code generator free?

Yes. It is free, needs no account, and runs in your browser.

Can I print the card at a print shop?

Yes. Download the PNG card, or send the SVG file to a print shop for stickers and signs.

Can I add my logo to the code?

This tool does not place a logo over the code, because covering part of a code can cause scan failures. Add your logo next to the code in your own design instead.

Do I need a different code for each technician?

No. The code points to your business profile, so one code works for everyone. Use one code per location.
