QR Chunker

QR Chunker is a tool to split a long text into a sequence of QR codes to be sent or printed, and a wizard to manually scan printed QRs (or pictures from the gallery), one by one, and re-create the long text.

Features

• Generate QR Codes: Split long text into chunks and generate QR codes for each chunk. You can define the chunk length between 500 and 2950 characters (default is 2000 characters). Above 2950 characters there are tech limitations.
• Save and Share QR Codes: Save individual QR codes as PNG files or share them directly from your mobile device.
• Decode QR Codes: Upload an image or capture one using your webcam to decode QR codes. Append decoded text to the existing text or clear the current scan and total text.
• Download All QR Codes: Download all generated QR codes in sequence automatically.
