How It Works

Three steps to a compact QR.

From raw text to scannable QR in milliseconds — simple by design.

1
Paste or type your text
Drop in any text — a URL, JSON, a Thai message, or a developer token. No setup needed.
2
QRzip picks the best algorithm
Our engine benchmarks 9 lossless algorithms and auto-selects the one that produces the smallest encoded payload for your specific text.
3
Get a compact, scannable QR
QR is generated instantly in your browser. Download PNG, embed, or share — readable by any camera app.
Documentation

Terminal & CLI Manual

QRzip CLI provides powerful encoding and decoding features straight from your terminal.

Installation

npm install -g qrzip-cli

Basic Usage

Encode text and output a compact QR payload string:

qrzip encode "Hello World"

Decode a QRzip payload back to text:

qrzip decode "QZR|...payload..."

Advanced Commands & Password Support

  • qrzip encode "text" -p "secret" — Encrypt the payload using AES-GCM with a password.
  • qrzip decode "QZP|..." -p "secret" — Decrypt a password-protected payload.
  • qrzip encode "text" --output image.png — Encode and save as a PNG image directly.
  • qrzip decode scan.png — Read and decode a QR code from an image file.
  • qrzip --help — Show all available commands and flags.
