Offline QR Code Generator and Label Sheets

Free QR sites want your link, your Wi-Fi password or your contact details uploaded to them, put their own redirect in the middle, and make you do one code at a time. This app builds standard QR codes in your browser with no upload and no redirect, in bulk, and lays them out on label sheets.

On Create one, choose what the code holds, fill the fields and pick colours and error correction, then download SVG or PNG. On Batch and label sheet, paste or load a CSV with a label and a value per row, choose the sheet layout and print. Scan one printed copy with two phones before you print a batch.

What is inside:

• Create one, Batch and label sheet, and About and self-test tabs
• Payloads: web link, WhatsApp chat link, contact card (vCard 3.0), Wi-Fi, plain text, phone, email and a readable payment request block
• A from-scratch encoder: numeric, alphanumeric and byte modes, versions 1 to 40, error correction L, M, Q and H, all eight masks with automatic choice
• SVG and PNG download with your colours, and a zip of every code in a batch
• A4 label sheets with a caption under each code and a warning when the printed squares are too small to scan reliably
• Self-test against the worked example in the QR standard, JSON backup, example data

Who it is for: shops, restaurants, offices and event teams that need menu, Wi-Fi, WhatsApp, review or product-page codes in quantity.

What it is not: The payment request option prints a clear text block. It is not a bank or wallet payment QR, so banking apps will not pay from it. It makes QR codes only: no barcodes and no GS1 codes. Very long text needs a larger printed code.

How it differs: The barcode-generator-and-label-sheet-app makes product barcodes (EAN, UPC, Code 128). This app makes QR codes. The whatsapp-click-to-chat-link-builder-uae makes wa.me links and QR sheets for phone lists, while this one is a general QR tool.

Tested: 116 scripted browser checks. The encoder reproduces the worked example in the QR standard and the capacity limits. 320 random payloads across modes, versions and error levels were rendered and decoded: ZXing-C++ and ZBar read all 320. OpenCV was used as a third check; its older detector read 284 of 300 non-ECI codes, its newer Aruco detector read all 300, which tells you the denser codes are valid but some scanners are fussier than others. A 30-code label sheet was printed to PDF and all 30 codes decoded from the rendered pages. Not tested: paper scans with a range of phones. It was tested in Chromium only. Firefox, Safari, a real phone and a real printer were not available for testing.
