arkalabel

A free browser generator for 38 barcode types and QR codes, PNG and SVG download, and a barcode API that also returns PDF, JPEG, GIF and TIFF. Commercial use is allowed on every plan, there is no watermark, and the same key renders ZPL labels. One barcode per request; no batch endpoint.

TEC-IT

A broad catalogue, including GS1 DataBar, composite codes, MaxiCode, Han Xin and DotCode. The free generator is for non-commercial or private use with a backlink; yearly subscriptions add SVG, up to 600 DPI, batch support and API integration.

LabelZoom

A conversion service between printer languages, documents and images, including ZPL, EPL, TSPL, DPL, PDF and images, with official SDKs in eight languages. Its free tier is watermarked.

Labelary

A ZPL rendering API rather than a barcode generator: barcodes come as part of a rendered ZPL label, in PNG, PDF and several printer languages.

Self-hosted barcode libraries

Open-source libraries such as Zint or python-barcode run inside your own software, with no request limits and no data leaving your systems, in exchange for building and maintaining the integration yourself.

Desktop barcode software

Installed label and barcode design programs suit people who lay out labels by hand and print from one computer, rather than generating codes from software or a browser.

How to choose

  • Whether you will use the barcodes commercially, and what each free tier's terms allow.
  • Which symbologies you need: check the exact types, not just the count.
  • Which file formats you need, and at what resolution.
  • Whether you generate codes one at a time, in batches, or from your own software through an API.
  • Whether you also print ZPL labels, and want both from one service.
  • How you prefer to pay: free, monthly, or a yearly subscription.

Try your own labels in the online ZPL viewer before committing to an integration, and use the side-by-side pages to compare figures.
