Labeloid lets you open ZPL files from the file dialog, drag them into the app, or double-click a .zpl file in Windows Explorer. The rendered label appears alongside its source code in the same desktop workspace. Use Browse folder to find ZPL files in a folder and browse through them in the app.

  • Open from the file dialog.
  • Drag and drop a ZPL file into Labeloid.
  • Double-click a .zpl file in Windows Explorer.

Edit raw ZPL, then Apply

The built-in source editor lets you change raw ZPL with syntax highlighting. When you are ready, click Apply. Labeloid saves the edited ZPL and redraws the label.

The preview does not update while you type; Apply is the explicit edit-to-render step.

💡 Tip: Click a specific area in the label preview, and Labeloid highlights the corresponding ZPL code.

Print & convert

Print or export your ZPL labels

Print labels on any selected printer or send raw ZPL directly to Zebra printers for fast, precise output.

Labeloid also lets you export ZPL labels as PDF, PNG, or JPG — perfect for sharing, archiving, or using labels outside the printing workflow.

You can export your labels into any of these formats:

Navigate multi-label ZPL, one page at a time

Page thumbnails, navigation controls, and a page count make it easy to browse multi-page ZPL files while keeping the current label clearly in view.

Export multi-page ZPL filesBy default, Labeloid saves all pages in the ZPL file. To export only selected pages, enter page numbers and/or page ranges in the Page range field on the Rendering parameters tab.

Warnings + diagnostics

Spot potential ZPL issues in the source code

A file may contain invalid parameters, unknown commands, or non-standard ZPL. Labeloid surfaces warnings so you can spot potential issues in real time, adjust the source code, and render again.
