Generate QR codes for any content

What This Tool Does

The kittokit QR Code Generator creates scannable QR codes from four types of content: URLs, plain text, WiFi network credentials, and vCard contact information. Output is available as PNG (raster, ideal for web and digital use) and SVG (vector, ideal for print at any size).

Supported content types:

Type	What gets encoded	Example use
URL	Any web address	Link to your website, social profile, or online form
Text	Up to ~4,000 characters	A coupon code, a short message, a product serial
WiFi	SSID + password + security type	Guest network sign-in at a home, office, or event
vCard	Name, phone, email, address	Scannable business card contact

All four types generate a standard QR code that any smartphone camera app (iOS, Android) or QR reader can scan without a special app.

How It Works

QR codes encode data using a matrix of black and white squares following the ISO/IEC 18004 standard. The tool uses a client-side JavaScript QR library to:

1. Encode — convert your input into the QR bit string using the appropriate encoding mode (numeric, alphanumeric, byte, or Kanji).
2. Apply error correction — add Reed-Solomon redundancy blocks at the selected level (L/M/Q/H) so the code remains scannable even if up to 30% of it is obscured.
3. Render — draw the matrix onto an HTML canvas (for PNG) or build an inline SVG (for vector output).
4. Download — the canvas is exported as a PNG blob or the SVG is serialized for download. Nothing leaves your device.

What Are Common Use Cases?

Restaurant menus. Since 2020, QR-code menus have become standard in US restaurants. Print a QR code linking to your PDF menu or online ordering page and place it on tables or at the host stand.

Small business marketing. Add a QR code to business cards, flyers, and packaging that links directly to your Yelp listing, Google Business profile, or a special landing page — no URL typing required.

Event signage. Conference exhibitors, trade show booths, and pop-up shops use QR codes on banners to drive traffic to their website, app download, or lead capture form.

WiFi access for guests. Instead of reciting a complex WiFi password at a party, Airbnb, or vacation rental, display a QR code guests scan to join instantly. The WiFi QR type encodes the SSID, password, and security protocol in one code.

Digital business cards. Print a vCard QR code on your physical card. When a contact scans it, their phone offers to save your name, phone number, email, and address automatically — no manual data entry.

Product packaging. DTC brands use QR codes to link from packaging to instructional videos, warranty registration pages, or loyalty program sign-ups.

Classroom and education. Teachers use QR codes on printed handouts to link to supplemental videos, Google Forms quizzes, or classroom portals — making resources accessible without students manually typing URLs.

Frequently Asked Questions

What is the difference between static and dynamic QR codes? Static QR codes (what this tool generates) encode the destination directly. Dynamic QR codes use a short redirect URL managed by a third-party service, allowing the destination to be changed after printing. Dynamic codes require a paid subscription to services like Bitly or QR Tiger. For most personal and small business use, static codes are sufficient.

Will the QR code work without internet? The code itself does not require internet to scan. However, if it encodes a URL, the person scanning needs internet access to open the linked page. WiFi and vCard codes work entirely offline — they write data directly to the phone.

How small can a QR code be and still scan? The ISO standard recommends a minimum size of 0.4 × 0.4 inches (10 × 10 mm) for close-range scanning. For reliable scanning in various lighting conditions, 1 × 1 inch is a safer minimum for print.

Can I use the generated QR code commercially? Yes. The generated QR codes are yours to use for any purpose — personal, commercial, or non-profit — without attribution.
