Why Choose Our Generator?

Proprietary Engine

We do not use external libraries. The barcode generation engine was developed by our team and is being developed under the name HDF BarCode SDK – a professional solution used in production, logistics, and commercial systems.

This allows us to provide:

  • high precision and fast generation
  • compliance with GS1 standards and industry norms
  • stable operation
  • future development and integration possibilities

Export to PNG and SVG

  • PNG – ideal for websites, ERP systems, and PDF documents
  • SVG – vector format for printing labels, packaging, and production materials (no quality loss when scaling)

Full Customization

Adjust:

  • barcode and background colors
  • rotation
  • margins
  • proportions and quality
  • parameters matched to printer resolution

Free Commercial Use

Barcodes generated on this page can be used in both private and commercial projects - with no licensing fees.

Important Note About Scaling: although SVG allows unlimited resizing without losing sharpness, remember one golden rule:

maintaining the correct bar proportions is crucial.

A critical mistake can occur if you reduce the barcode width too much or scale it non-proportionally. Doing so may unintentionally violate the bar and space proportions defined in the barcode standard, making the code unreadable for scanners.

A good practice is to print your design after scaling and test it with a barcode reader, or preferably a verifier, to ensure the barcode still meets readability standards.

Integrate the Engine Into Your Application

Our online generator is powered by proprietary HDF BarCode SDK libraries.

If you need barcode generation directly inside your system (ERP, WMS, manufacturing, e-commerce, SaaS), you can integrate the SDK into your environment.

We provide:

  • 114 barcode types
  • High performance and standards compliance
  • Full control over generation parameters

How does the barcode generator work?
The barcode generator converts a string of text characters e.g. 1234567890ABCD into a barcode. After selecting a barcode, e.g. EAN-8, EAN-13, GS1-128, the generator converts the characters entered by the user into a barcode. For simple barcodes, one character corresponds to one set of bars, for complex codes, e.g. Code 128, the characters are initially converted to a specific symbol, then the algorithm selects the appropriate set of spaces and dashes.
Barcode for Printing – Which Format Is Best?
For professional printing (labels, packaging, marketing materials), the best format is definitely SVG. As a vector graphic, it guarantees perfectly sharp edges and eliminates the blurring often present in raster formats (JPG, PNG), which can prevent barcode scanners from reading the code correctly.
