ℹ️ About This Barcode Generator Tool

Barcodes are machine-readable patterns of parallel lines that encode data in a format scanners can read instantly. They are used everywhere — from supermarket product labels to warehouse inventory systems, shipping labels, hospital patient wristbands, library books, airline boarding passes, and government identification documents. This free online barcode generator supports all major 1D barcode formats plus QR codes, allowing you to create professional scannable barcodes without any software installation or registration.

The tool supports CODE128 — the most versatile and widely used 1D barcode format that can encode any ASCII character including letters, numbers, and symbols, making it ideal for inventory codes, serial numbers, and shipping labels. EAN-13 is the international standard for retail product barcodes used on most consumer goods sold globally. UPC-A (Universal Product Code) is the North American retail standard. EAN-8 is a shorter version for small products. CODE39 is used in automotive, defense, and healthcare. ITF-14 is used for shipping cartons. Pharmacode is used in the pharmaceutical industry.

Beyond basic generation, this tool offers professional customization: choose barcode and background colors, adjust bar width and height, control margins, select font size and family, toggle bold text, and place text above or below the barcode. Download in PNG (for web and documents), SVG (scalable vector, ideal for print at any resolution), or PDF (print-ready). The batch generator lets you upload a CSV file with hundreds of values and download all barcodes at once as a ZIP file — saving significant time in inventory and logistics workflows.

The QR Code generator creates 2D barcodes that can store URLs, contact information, WiFi credentials, plain text, and more. QR codes are scannable by any modern smartphone camera without a dedicated app, making them ideal for marketing materials, product packaging, menus, and contactless information sharing. You can customize the QR color, background color, size, and error correction level.

This suite goes well beyond generation. The built-in Scanner decodes a barcode or QR code from your device camera or from any image you upload or drag in — CODE128, EAN/UPC, CODE39, QR and more — and lets you copy the decoded value or send it straight into the generator to re-create or modify it. A Barcode Information panel shows the barcode type, character count, encoding class (numeric, alphanumeric or full ASCII), the check digit for EAN/UPC-family codes, and which scanners the symbology is intended for, so you can confirm a code is valid before printing thousands of labels. Because everything runs locally, none of the images you scan or values you encode ever leave your device.

The Product Label Designer turns a raw barcode into a finished, print-ready label. Enter a company name, product name, SKU, price, batch number and expiry, choose the barcode symbology, and the tool composes a tidy label with the barcode embedded — ready to print on a thermal, Zebra, Dymo or Brother label printer, or to download as a PNG for a design tool or an A4 label sheet. This is exactly what retail shelves, warehouse bins, pharmacy packaging and shipping cartons need, and it removes the usual round-trip through a separate design application.

All barcode generation happens entirely in your browser — no data is ever sent to any server. Your barcode values and history are private. The recent barcodes history feature saves your last 20 generated barcodes in LocalStorage for quick regeneration, and you can regenerate any of them with a single click. The whole suite is built with lightweight, well-established libraries (JsBarcode for 1D symbologies, a QR engine for 2D, and a standards-based decoder for scanning), so it loads fast, works on phones and desktops alike, and keeps working offline once the page has loaded.

📖 How to Use:

1. Enter the text or number you want to encode in the input field.
2. Select the barcode format appropriate for your use case (CODE128 works for most purposes).
3. Adjust size, colors, font, and margin using the controls.
4. Click PNG, SVG, or PDF to download. Use Print for instant printing.
5. For QR codes, switch to the QR Code tab and enter your URL or text.
6. For multiple barcodes, use the Batch tab — upload a CSV or paste values.

📦 Supported Barcode Formats:

💡 Use Cases:

• Education: Student ID cards, library cards.
• Marketing: QR codes on flyers, menus, business cards.

🖨 Printing Guide:

• Thermal / Zebra / Dymo / Brother label printers: Download the SVG (or the label PNG) and print at 100% scale — never "fit to page", which distorts the bars and can make a code unscannable. Match the label size to your media (e.g. 40×20 mm, 4×6 in).
• A4 / Letter label sheets: Use the Batch tab's "Print A4" to lay many barcodes onto a standard sheet, then feed pre-cut label stock through a normal laser or inkjet printer.
• Quiet zone & contrast: Keep a white margin (quiet zone) on both sides and use dark bars on a light background — the scanner needs the contrast. Avoid printing barcodes on coloured or reflective surfaces.
• Resolution: Prefer SVG for print because it is resolution-independent; if you must use a raster, use the largest size preset and 300 DPI or higher.
• Verify before a big run: Print one label, scan it with the built-in Scanner or a phone, and confirm it decodes to the exact value before printing the whole batch.

🧪 Examples:

• Retail product: EAN-13 4006381333931 → scannable at any supermarket POS.
• Inventory item: CODE128 WH-A12-SHELF-045 → any ASCII, ideal for internal SKUs.
• Shipping carton: ITF-14 10012345678902 → outer-case marking.
• Marketing QR: encode https://apnesoftware.com → scannable by any phone camera.

🛠 Troubleshooting:

• "Invalid input for this format": EAN-13 needs exactly 13 digits, UPC-A 12, EAN-8 8. Use CODE128 if your data has letters or a variable length.
• Barcode won't scan after printing: You likely scaled it — reprint at 100%, keep the quiet-zone margins, and ensure dark-on-light contrast.
• Scanner finds nothing in an image: Use a sharp, well-lit, straight-on photo where the whole code and its white margins are visible; blurry or angled shots often fail.
• Camera won't start: Grant the browser camera permission and use HTTPS; otherwise use Upload Image, which works everywhere.
• Check digit mismatch: For EAN/UPC the last digit is a computed check digit — enter the full correct number, or let a GS1 calculator work it out.
• History or theme not saved: These live in your browser's LocalStorage; private/incognito mode or clearing site data will reset them.
