Review QR Code Generator
Print-ready QR for business cards, vehicle decals, and lobby signs. Scans straight to your Google review form.
Where a review QR code actually gets scanned
A QR code is only useful if someone points a camera at it. Put your review QR where the customer is already looking: while waiting, while paying, while the job is fresh.
Placements worth trying:
- Invoice footer (digital and printed) - the customer is looking at it right after the job.
- Back of the business card - every handshake becomes a review opportunity.
- Service van decal - parked at the curb all day. Neighbors scan it too.
- Table tent or checkout counter - works for restaurants, retail, salons, gyms.
- Lobby or waiting area sign - bored phones come out. Use the downloadable poster below.
- Email signature - attach the PNG, link to the review URL. Works in every client.
QR code best practices for small business
Size matters
Minimum print size is roughly 1 inch square when viewed from arm's length, and 4+ inches for anything further than three feet. Vehicle decals should be 6-10 inches. Bigger is better - never shrink the QR below the point where its error-correction pattern is readable.
Don't distort brand colors
You can tint the QR code (use a dark color for the foreground), but keep the contrast ratio high. Light foregrounds on light backgrounds fail to scan. Stick to the 4.5:1 WCAG contrast rule for text and you'll be safe.
Always print the call-to-action
A QR code by itself is a silent square. Pair it with a short line: "Scan to leave a Google review" or "How did we do? Tell us on Google." A code with no explanation gets ignored.
Test before you print 500 of them
Print one proof, scan it from three different phones and two different distances. Only then send the file to the print shop. A typo'd URL on 500 business cards is a painful lesson.
Print shop specs
When sending the QR to a print shop, use these settings:
- File format: SVG (scales losslessly) or 300+ DPI PNG
- Color mode: CMYK for print, RGB for screen
- Quiet zone: Leave at least 4 modules of white space around the code - the tool already does this
- Error correction: We use H (highest) so the code still scans with the 5-star badge in the center
How this tool works
The QR code is generated entirely in your browser using the open-source qrcode library. The URL is never sent to our servers. The resulting image is yours to keep, print, and distribute - no watermark, no expiration, no tracking pixel.
Send review requests with Elmob.ai
A QR code covers the printed side. On the Solo Operator plan and above, Elmob.ai can also text your review link to customers, so the person holding the invoice has the link on their phone too. See plans.
Questions about this tool
Is this QR code actually printable?
Yes. The tool generates high-resolution SVG and PNG (1024×1024) files. SVG scales to any size without losing quality - perfect for vehicle decals, yard signs, and large-format print. PNG is fine for business cards, receipts, and stickers.
Do I need a Google Business Profile?
Yes. The QR code points to your Google review URL, which requires a verified GBP listing. If you don't have one yet, create it at business.google.com first.
Will the QR code expire?
No. QR codes don't expire - they're just an image of a URL. As long as your Google Business Profile exists, the QR code works.
Can I use my own logo in the middle of the QR code?
Not in this tool. It can put a star badge in the center, and you can pick the colors. To add your own logo, export the SVG and finish it in Figma or Illustrator. The code uses the highest error correction level, so a small center logo usually still scans. Test it before printing.
Where should I put the QR code?
Places where the customer is already looking: 1) printed on every invoice, 2) a sticker on the service vehicle, 3) a lobby or reception wall, 4) business cards, 5) thank-you email signatures. Combine physical and digital placements.
What happens when someone scans it?
The QR encodes the same direct review URL as our review link generator, so scanning opens your Google review form. The customer picks the star rating themselves. No link can pre-select stars.
Does the QR work on iPhones and Androids?
Yes on both. iPhone's camera app and all modern Android cameras recognize QR codes natively. Some older Androids may need a QR app.
