What Is a QR Code Generator?
A QR code generator is a tool that converts information — a website address, a phone number, a message, or plain text — into a square, scannable barcode. When someone points their phone camera at it, the code instantly opens the linked content, whether that’s a webpage, a pre-filled WhatsApp chat, or a draft email.
QR codes have become a standard part of offline-to-online marketing. You’ll see them on packaging, storefront windows, invoices, event tickets, and social media posts, because they remove the friction of typing a long URL or saving a new contact by hand.
How to Use Our Free QR Code Generator
Creating a QR code takes four simple steps:
- Choose a type. Select Link, WhatsApp, Email, or Text from the tabs at the top of the tool.
- Fill in your details. Enter the URL, phone number and message, email address, or text you want the code to carry.
- Customize the look. Open “Customize appearance” to change the QR color, background color, size, and error-correction level.
- Generate and download. Click “Generate QR code,” then download the PNG or copy it straight into a document or design file.
There’s no account to create and no limit on how many codes you can generate.
Types of QR Codes You Can Create
Website / URL QR Code
Paste in any web address and the tool builds a QR code that opens that page directly. This is the most common use case — linking a printed ad, poster, or packaging to your website, product page, or online store.
WhatsApp QR Code
Generate a QR code that opens WhatsApp with your business number and a pre-filled message already typed in. This is ideal for customer support desks, retail counters, and service businesses that want to turn foot traffic into WhatsApp conversations instantly.
Email QR Code
Create a code that opens the visitor’s email app with your recipient address, subject line, and message body already filled in. Useful for feedback forms, RFQ requests, and support tickets where you want a structured message every time.
Plain Text QR Code
Encode any text directly into the code — a Wi-Fi password, a coupon code, an address, or a short note. Scanning it displays the text immediately, with nothing to click through.
Customize Your QR Code
Most free QR generators only give you a plain black-and-white square. This tool lets you match your QR code to your brand:
- QR and background color — pick any hex color, or choose from ready-made presets.
- Size — export at 200×200, 300×300, or 450×450 pixels depending on whether it’s for a screen, a flyer, or large-format print.
- Error correction level — higher levels keep the code scannable even if part of it is covered by a logo, folded, or slightly damaged.
- Built-in contrast check — the tool automatically warns you if your color choice is too low-contrast to scan reliably, so you never publish a code that doesn’t work.
