Barcode Maker: Gen & Scan

Need a barcode right now? Barcode Maker generates production-quality barcodes directly on your phone — no web browser, no account, no internet required.

Whether you are a small business owner creating product labels, a developer testing a POS system, a teacher preparing classroom materials, or simply someone who needs a scannable barcode fast, Barcode Maker handles the task with precision.

Supported Barcode Formats

EAN-13 — The international retail standard used on virtually every product sold in stores worldwide.

UPC-A — The North American retail standard, fully compatible with point-of-sale systems.

Code 128 — High-density alphanumeric encoding for logistics, shipping, and inventory management.

Code 39 — The industrial standard used across manufacturing, automotive, and military supply chains.

ISBN — Generate book barcodes with automatic ISBN-13 formatting for publishers and sellers.

Automatic Check Digit Calculation

For EAN-13, UPC-A, and ISBN barcodes, Barcode Maker automatically computes the correct check digit from your input. Type your data, tap Calculate, and the app appends the mathematically verified final digit. No spreadsheet formulas, no manual lookups.

Export in Multiple Formats

Once you have generated a barcode:

Export as PNG to your Downloads folder for use in documents, labels, or websites.

Export as PDF for direct inclusion in print-ready files.

Share instantly via any installed app using the standard Android share sheet.

Print directly from the app on any connected AirPrint or Mopria-compatible printer.

Custom text labels can be added to any barcode — useful for product names, SKUs, or any annotation you need to appear beneath the bars.

Built-In Barcode Scanner

The Scanner tab uses your device camera to read barcodes in real time. Point at any EAN-13, UPC-A, Code 128, or Code 39 barcode and the data is decoded instantly. Scanned results can be loaded directly into the generator to duplicate or modify an existing barcode.

Barcode History

Every barcode you save is stored locally in the History tab with its type, data, label, and creation timestamp. Filter by barcode type, search by name or number, and delete individual entries or clear the entire library. Your barcode history never leaves your device.

Real-Time Input Validation

The input field validates your data against the rules of the selected barcode type as you type. Incorrect length, invalid characters, or malformed ISBN values are flagged immediately — before you attempt to generate anything.

Clean Generation Experience

The core generation workflow is clean and uninterrupted.

Part of the HALOCORE suite of free Android tools — practical, well-built apps that respect your time and your data.
