QR Code Types You Can Create

  • URL / Website: Anyone scanning your QR code opens a specific web page in their browser. Perfect for business cards, posters, and product packaging.
  • vCard Contact: Includes name, phone, email, company, and website. When scanned, it saves directly to the user's contacts — ideal for networking events.
  • Email: Pre-fills the recipient, subject, and body. Scanning opens the default mail app with fields populated. Great for support desks and feedback forms.
  • Phone / SMS / Text: Trigger a phone call or pre-compose an SMS message. Also supports plain text for simple information sharing.

Why Use a Client-Side QR Generator?

100% Private

Many QR generators send your data to a server to render the QR image. ByteBox uses a JavaScript library (qrcode.js) to render the QR code directly in your browser.

Download as PNG or SVG

PNG for social media or quick sharing — SVG for print design, vector editing software like Illustrator or Inkscape, or high-resolution signage.

Unlimited, No Account

Create as many QR codes as you want. No daily limits, no watermark, no signup. The code renders instantly as you type.

Frequently Asked Questions

Are the QR codes permanent?

The QR code encodes your data directly. As long as the destination URL (if using a URL code) stays active, the QR code will never expire. There's no database or server dependency.

Can I customize the color or add a logo?

Currently we support black-on-white standard QR codes. For custom colors or embedded logos, download the SVG and edit it in vector design software.

What format should I use for print?

SVG is best for print — it scales to any size without losing quality. For digital use, PNG at the highest resolution setting works perfectly.

How much data can a QR code hold?

A standard QR code holds up to 4,296 alphanumeric characters or 7,089 numeric digits. For URLs, you'll almost never hit this limit — typical URLs are well under 200 characters.
