Free Barcode Generator – Create Custom Barcodes Online Instantly

Every product needs a barcode. Every warehouse needs labels. Every event ticket, shipping package, and inventory item relies on barcode scanning to function efficiently. Creating professional barcodes used to require expensive software, specialized knowledge, or a paid subscription to a platform that locked your output behind a paywall. Transfonic's free barcode generator removes all of that — generate custom barcodes for any format, any use case, and any industry instantly online with full customization, PNG and SVG download, no account required, and no watermark on your output.

How to Create a Barcode Online Free

Generating a barcode with Transfonic takes less than a minute. Enter your barcode value — a product number, serial code, URL, or any string of related data. Next, pick your barcode form from a complete list of supported symbologies. Then set the parameters, like line width, bar height and margin settings, as well as display value settings. Preview your barcode live as you customize settings and then download immediately as a high-resolution PNG file for print, or export to an SVG vector file to use in your designs. No account, no watermark, no limits

For creating QR codes alongside barcodes for the same products and workflows, Transfonic's free QR code generator generates custom QR codes with full color and design customization in one place.

Supported Barcode Formats

Transfonic's free barcode maker supports 12 industry-standard barcode formats covering every major use case across retail, logistics, healthcare, and manufacturing:

• EAN-13: the global standard for retail product identification, used worldwide on consumer goods
  

• EAN-8: compact version of EAN-13 for small product packaging with limited label space
  

• UPC-A: the standard retail barcode used across North American product checkouts
  

• UPC-E: compressed UPC format for smaller items with limited packaging space
  

• Code 128: versatile alphanumeric barcode for shipping, packaging, and high-density data encoding
  

• Code 39: widely used in automotive, manufacturing, and warehouse labeling workflows
  

• Code 93: a higher-density version of Code 39 used in logistics and inventory management
  

• ITF: numeric barcode used in logistics and outer packaging for cartons and pallets
  

• PDF417: high-capacity 2D barcode used on government IDs, boarding passes, and documents
  

• DataMatrix: compact 2D barcode used in electronics, healthcare, and small item labeling
  

• Aztec Code: dense 2D barcode used on transport tickets and boarding passes
  

• QR Code: universally recognized 2D barcode for URLs, contacts and digital content
  

In testing, a custom EAN-13 barcode with adjusted line width and bar height was generated and downloaded as a clean SVG vector file in under 2 seconds, scanning correctly on both handheld and mobile barcode scanners without a single read error.

Who Is This Tool For?

Transfonic's free barcode generator online is built for anyone who needs professional barcodes without expensive software. Small business owners and retailers generate EAN and UPC barcodes for product labeling and point-of-sale scanning. Warehouse and logistics managers generate Code 128 and ITF barcodes for inventory tracking and shipping labels. Developers and system integrators generate barcodes for integration into inventory management systems and e-commerce platforms. Event organizers generate PDF417 and Aztec barcodes for tickets and access control systems. Product creators and Etsy sellers generate barcodes for handmade and custom products requiring retail-ready labeling. For scanning barcodes and QR codes instead of generating them, Transfonic's free QR code scanner decodes any barcode or QR code instantly from a camera or uploaded image.

Free Barcode Generator – PNG & SVG Download, No Limits

All barcodes you generate on Transfonic are free (no account needed, no watermark in your output). Get a high-quality HOSO stamp graphic in PNG to print directly, or utilize the SVG vector file for easily resizing on design software, packaging layouts and print-ready artwork. Its SVG vector output is a clear advantage over the majority of free barcode-generating utilities that only offer pixel-based PNG downloads (SVG scales infinitely without loss of image quality, which makes it suited for professional print production). No limits (in terms of number of generations per day) and absolutely no forced upgrade prompt at any point.

For other creative studio tools alongside barcode generation, Transfonic's free studio tools cover QR codes, screen recording, audio recording, and more in one place.
