Free QR Code Generator for Developers: No Limits, No Signup

Need QR codes for your project? Here is how to generate them instantly with no account required.

The Problem with QR Code Generators

Most QR code tools either:

  • Require signup for basic features
  • Watermark your codes
  • Limit downloads
  • Charge for high-resolution exports

A Better Solution

knu.day generates QR codes for free as part of its URL shortener. Here is how it works:

Step 1: Create a Short Link

Go to knu.day and paste your URL. You will get a short link like knu.day/abc123.

Step 2: Download Your QR Code

Every short link automatically gets a QR code. Just visit:

\n
Or click the QR button on your link stats page.

Step 3: Track Scans

The best part? Every scan is tracked. You can see:

  • Total scans
  • Unique visitors
  • Countries
  • Devices
  • Browsers

API Access

Need to generate QR codes programmatically? Use the API:

Use Cases

  • Event Registration: Link to signup forms
  • Product Packaging: Link to manuals or support
  • Business Cards: Link to your portfolio
  • Restaurant Menus: Link to your online menu
  • Marketing Campaigns: Track which print ads perform best

Why It Is Free

knu.day is a side project I built because existing QR tools were overpriced. The entire service runs on minimal infrastructure, so there is no reason to charge.

Try it at knu.day.
