Download LabelZoom
LabelZoom converts barcode labels between thermal printer languages and ordinary document formats. It accepts ZPL, EPL, DPL, TSPL, IPL and SBPL on one side and PDF, PNG, JPEG, GIF and BMP on the other, in both directions. A browser viewer renders ZPL as a PDF or PNG preview, and the same engine is available through a REST API with official SDKs for integration into warehouse and shipping systems.
The platform includes a Windows Label Designer for building ZPL templates on a visual canvas with dynamic fields and barcode elements. Finished designs can be sent directly to a connected thermal printer or exported in Blue Yonder .POF format. The online viewer and converter are free, while API access runs on a free watermarked tier and paid tiers with higher conversion limits.
LabelZoom has operated in production for over five years, serving warehouse, carrier and enterprise label workflows and processing millions of conversions. Enterprise plans carry service level agreements of up to 99.99 percent uptime, and the company reports customers in more than one hundred countries. The product is closed source and delivered as hosted services, a desktop application and client libraries.
