What is a QR code and how does it work?
A QR code (Quick Response) is a two-dimensional barcode that can be scanned with a smartphone camera. Unlike traditional barcodes, QR codes store data both horizontally and vertically, allowing them to encode significantly more information - up to approximately 3,000 alphanumeric characters.
The QR code was developed in 1994 by the Japanese company Denso Wave (part of the Toyota group) for tracking car parts. Today, QR codes are widely used in marketing, hospitality, logistics, and business communication. They gained particular popularity during the COVID-19 pandemic, when restaurants began replacing paper menus with QR codes.
How to use the free QR code generator
Creating a QR code takes just a few seconds:
2. Enter the data

Customize the appearance (colors, size, margin) and download as PNG or SVG.
QR code types - URL, vCard, email, phone, text
The free QR code generator supports five data types - each useful in different situations:
URL
A link to a website. After scanning, the phone opens the page in the browser. Ideal for business cards, flyers, and posters.Text
Any text up to 3,000 characters. After scanning, the phone displays the text on screen. Useful for discount coupons and short instructions.vCard business card
A digital business card with contact data (name, company, phone, email, address). After scanning, the phone offers to save the contact. Ideal for professional business cards.Email
An email address with optional subject and body. After scanning, the phone opens the mail app with a pre-filled form.Phone
A phone number. After scanning, the phone offers to make a call. Useful for hotlines and customer support.

QR code technical specifications
Knowing the technical parameters helps create QR codes that are readable in all conditions:
- Data capacity - a QR code can hold up to 7,089 digits, 4,296 alphanumeric characters, or 2,953 bytes of binary data. In practice, this is more than enough for URLs and business cards.
- Reed-Solomon error correction - a mathematical algorithm that enables reading the code even when part of it is damaged or obscured. Levels: L (7%), M (15%), Q (25%), H (30%).
- Margin - the white area around the code required for proper scanning. The recommended minimum is 4 modules (code units).
- Minimum print size - for standard scanning conditions, the code should be at least 2×2 cm. For large format printing (banners, billboards), scale up accordingly.
- Contrast - the contrast ratio between the code and background should be at least 3:1. The generator automatically warns about too low contrast.
QR code applications - business cards, flyers, restaurant menus
QR codes find use in many industries and scenarios:
Business cards
A vCard code on a business card lets the recipient save the contact with a single scan, without manually typing data.Restaurant and cafe menus
A QR code on the table directs to a digital menu. A hygienic solution popular since the COVID-19 pandemic.Flyers and posters
QR code with a link to a product page, registration form, or special offer.Product packaging
Link to user manual, warranty card, or manufacturer website.Medical offices
QR codes on patient cards linking to the patient portal or appointment booking system.Real estate
Codes on banners linking to the full listing with photo gallery and details.Warehouses and logistics
QR labels for tracking product batches, warehouse locations, and shipment history.E-commerce
Codes on packaging linking to return instructions, customer reviews, or loyalty programs.Events and conferences
Tickets with QR codes for quick verification at entry.

QR code appearance customization
The generator lets you customize several parameters affecting the appearance and readability of the code:
- Size (px) - code dimension in pixels. For standard print (flyers, business cards) choose 300–500 px. For digital use, 150–200 px is sufficient.
- Margin - white area around the code required for proper scanning. Recommended value is 2–4. A value of 0 may make scanning difficult on a dark background.
- QR code color - black by default (#000000). You can change it to any dark color matching your visual identity.
- Background color - white by default (#ffffff). You can change it to any light color. The generator will warn if contrast is too low.
Tip: Maintain high contrast between the code and background (minimum 3:1). A dark code on a light background scans most easily.
L (Low)7%
M (Medium)15%
Q (Quartile)25%
H (High)30%
Error correction levels - L, M, Q, H
Error correction is a mechanism that enables reading a QR code even when part of it is damaged, dirty, or obscured. The generator uses the Reed-Solomon algorithm, a standard in QR codes.
- L (Low) - 7% - least redundancy, code is most compact. Choose when the code will be used in ideal conditions (screen, high-quality print).
- M (Medium) - 15% - default value, a good balance between capacity and resilience. Suitable for most applications.
- Q (Quartile) - 25% - greater resistance to damage. Choose for codes printed on materials prone to getting dirty.
- H (High) - 30% - highest resilience. Recommended for outdoor print materials, packaging, and situations where the code may be partially obscured (e.g., a logo in the center).
Note: A higher correction level means a larger and more complex code. With large amounts of data and level H, the code can become very dense.

QR code printing tips
To ensure the QR code is readable after printing, follow a few rules:
Minimum size
The code should be at least 2×2 cm for close-range scanning. The greater the scanning distance, the larger the code must be.Contrast
Dark code on a light background. Avoid pastel colors and low contrast.Margin around the code
Keep empty space around the code. Do not place other graphic elements too close - the margin is essential for proper scanning.Testing
Before mass printing, test the code on different phones and in various lighting conditions.Correction level
For outdoor print and materials prone to damage, choose level Q or H.
