Kalenux QR & Barcode Tool (published as QR Bar Code) is a free, browser-based platform for generating, customising, scanning and exporting QR codes and barcodes, developed by Kalenux.[1] It supports 17 QR code types and 19 barcode formats, more than 35 formats in total, with design controls, camera and image scanning, batch creation and PNG, SVG and PDF export.[1] Codes are generated in the browser with no account, and the site is operated by Kalenux Bilişim in Istanbul.[2]
01 /Overview
QR Bar Code is a free, browser-based platform for generating, customising, scanning and exporting QR codes and barcodes. It is not just a QR generator: it combines the depth of a professional QR design tool, the format coverage of a barcode generator and the convenience of a scanner in one place.[1]
Codes can be created one at a time or in batch, and exported as PNG, SVG or PDF for web, print, packaging, labels, menus and campaigns. A built-in scanner decodes codes through the device camera or from an uploaded image, so users can create and read codes on the same platform, in nine languages, with no account.[1]
02 /History and motivation
Kalenux describes most QR generators as either too basic or too locked down. Some create a simple code with almost no design control; some offer customisation but push users toward sign-up, subscriptions, dynamic-code limits or branded workflows; others handle QR codes but ignore barcodes entirely, forcing users to switch tools for retail, inventory, logistics, events and marketing.[1]
The platform was built to bring the whole workflow into one free, browser-based tool: generate QR codes, create industry barcode formats, customise professional designs, scan with a camera, decode uploaded images, export print-ready files and batch-create codes.[1]
“Something this useful should not cost you an account, a subscription, or control over your data.”[1]
03 /How it works
Codes are built in real time with live visualisation; the whole process typically takes under 30 seconds from input to download, and generation itself takes under a second.[2]
04 /Supported formats
The platform covers 17 QR code types and 19 barcode formats.[1]
| Family | Count | Examples |
|---|---|---|
| QR code types | 17 | URL, plain text, vCard contact, WiFi credentials, payments, business details |
| Barcode formats | 19 | EAN-13, UPC, Code 128, Code 39, ITF-14, MSI, Codabar |
| Export formats | 3 | PNG (raster), SVG (infinitely scalable), PDF (print-ready) |
QR output follows the ISO/IEC 18004 standard and includes error correction of up to 30% data recovery, for reliable scanning in dim light, with minor damage or at varying distances.[2]
05 /Design and customisation
Codes go far beyond black-and-white squares. Users can upload a logo, apply gradients, set custom foreground and eye colours, and choose from 22 dot shapes, 16 eye-frame styles and 16 eye-ball styles.[1]
| Control | Options |
|---|---|
| Logo | Upload a brand logo or image into the code |
| Colour | Foreground, background, gradients and separate eye colours |
| Shapes | 22 dot shapes · 16 eye frames · 16 eye balls |
| Error correction | Levels L, M, Q and H |
| Output size | 100 px up to 4K resolution |
06 /Scanner
A built-in scanner reads QR codes and barcodes live through the device camera or decodes them from an uploaded image, directly in the browser: no separate scanner app is needed.[1][5]
07 /Batch creation
The batch tool generates dozens or hundreds of QR codes or barcodes at once and downloads them together, without an account: used for inventory, conferences, product lines, packaging, events and education.[1][2]
One reviewer reports generating 500 unique QR codes in under a minute for a product-labelling workflow.[7]
08 /Privacy and licensing
All generation happens in the browser; the site states that data never reaches its servers, that it does not track users, and that codes never expire. Users keep full commercial rights with unlimited use.[2]
The service is free and supported by Google AdSense advertising, with a cookie-consent system covering essential, analytics and advertising cookies.[2][6]
09 /Languages
The interface is fully localised in nine languages.[2]
10 /Reception
On the Kalenux product page, QR & Barcode Tool holds an average rating of 4.7 from six moderated reviews.[7] The platform itself reports more than 5 million users and a 4.9 rating.[2]
“The batch generation feature is a game-changer for our product labelling workflow. Generated 500 unique QR codes in under a minute. No other free tool offers this.”
“Client asked for Code 128 barcodes for their logistics operation. This was the only free tool that handled it properly and let me download in the right resolution. Solid.”
“Needed a QR generator that works in the field without reliable internet. The PWA mode works perfectly offline. Built a whole event check-in system around it.”
“We use this tool daily for generating barcodes for our retail inventory. Supports all the formats we need, outputs clean SVG and PNG. Huge time saver.”
