About Us | OB Barcode Generator

OB Barcode Generator is a free, professional-grade, client-side tool engineered by Molave Labs. We build precision utilities that help businesses, warehouse operators, retailers, and developers manage physical and digital assets with accuracy and speed — all without sacrificing user privacy.

                Our Core Belief: Generating a barcode should not require you to upload your sensitive inventory data to a remote server. All processing in OB Barcode Generator happens locally in your browser, by design.

Our Mission

The goal of OB Barcode Generator is to eliminate the unnecessary complexity and cost historically associated with professional barcode generation. Traditional desktop barcode software can cost hundreds of dollars per seat, requires installation, and often lacks modern browser-based accessibility. We believe this tooling should be free, fast, and universally available.

By running all logic directly in the browser using JavaScript, we deliver instant results without server round trips. This means no waiting, no rate limits, and no account creation — just open the app and generate.

What We Support

OB Barcode Generator supports the most widely-used barcode symbologies in modern logistics, retail, and inventory management:

QR Code: The most versatile matrix barcode. Ideal for embedding URLs, VCard contact info, Wi-Fi credentials, and other rich text payloads. QR Codes include error-correction capability (levels L, M, Q, H), allowing them to remain scannable even when partially damaged or obscured.
Code 128: A high-density linear barcode capable of encoding all 128 ASCII characters. It is the standard for shipping labels, courier packages, and warehouse management systems (WMS) globally. Code 128 is the most information-dense linear barcode for alphanumeric data.
Code 39: One of the oldest and most widely adopted linear barcodes. Commonly found in legacy industrial, automotive, and military applications. It encodes uppercase letters, digits, and a small set of special characters.
EAN-13: The International Article Number standard used by virtually every consumer product sold at retail globally (outside North America). The 13-digit format includes a country prefix and a check digit for validation.
UPC-A: The Universal Product Code used as the standard barcode for retail point-of-sale scanning in North America. UPC-A encodes 12 numeric digits and is essential for grocery, pharmacy, and general merchandise environments.

Engineering Standards

Every feature in OB Barcode Generator is built to a set of core engineering principles that reflect our commitment to quality:

Privacy First: No barcode data you enter ever leaves your machine. There is no backend server receiving your product codes, tracking URLs, or personal identifiers.
Open Web Standards: We use JsBarcode and a QR code generator library — both open-source, auditable implementations. There are no proprietary black-box generation algorithms.
Progressive Web App (PWA): OB Barcode Generator is installable on any device and functions fully offline. The entire application can be cached by your browser service worker after the first visit.
High-Fidelity Exports: SVG exports are lossless vector files, suitable for industrial-grade label printing at any DPI. PNG exports are rasterized at screen resolution for quick sharing and embedding.
Batch Processing: Our CSV batch engine allows you to import hundreds of rows and generate a print-ready label sheet in seconds, all without leaving the browser tab.

Choosing the Right Barcode Format

Selecting the correct symbology is critical for scanner compatibility and operational reliability. Here is a reference guide:

Use QR Code when your payload is a URL, contact info, or multi-line text.
Use Code 128 for internal tracking, warehouse labels, and alphanumeric SKU identifiers.
Use EAN-13 for international retail products registered with a GS1 company prefix.
Use UPC-A for North American retail point-of-sale (POS) scanning requirements.
Use Code 39 for compatibility with older industrial scanners or legacy systems that do not support Code 128.
