A real, scannable example

What the code contains

A Custom JSON QR code is encoded as raw JSON text. Scanning the example above produces exactly this:

{"sku":"A-1042","bin":"C7"}

Getting a Custom JSON code right

  • Whitespace counts towards the payload — minify before generating a production code.
  • Consumer scanners will show the raw JSON, so this is for your own software to read.
  • Short keys make a real difference: “id” instead of “identifier” can drop a symbol size.

How to make one, step by step

  1. Step 1

    Pick Custom JSON in the type grid.

  2. Step 2

    Fill in the fields — the preview updates as you type.

  3. Step 3

    Style the dots, colours, frame and logo.

  4. Step 4

    Download as PNG, SVG, PDF, JPEG or WEBP.

Questions

Is this Custom JSON QR code generator free?
Yes — unlimited codes, no account, no watermark and no expiry. Everything runs in your browser and nothing is uploaded.
What format does a Custom JSON QR code use?
It is encoded as raw JSON text, which is the format phone cameras and scanner apps already understand — no intermediate redirect service is involved.
Will the code stop working later?
No. The content is encoded directly into the pattern, so there is no server or short link that could go away. A printed code keeps working indefinitely.
