About ZPLMaster Pro

A tool born from a real pain point.

It all started with an oversized label.

If you've ever sold on a marketplace, you know the scene: it's 11 PM, you have 40 orders to ship tomorrow morning, and your Zebra printer is spitting out labels the size of a poster. The ZPL code came wrong from Shopee. Again.

That exact moment gave birth to ZPLMaster Pro.

Who we are

ZPLMaster Pro is a project by G-Max Solutions, an indie software studio founded by Claudio Max Galvão, a Brazilian developer and entrepreneur based in Cachoeiras de Macacu, RJ, Brazil.

G-Max Solutions builds practical tools for real e-commerce problems — no bureaucracy, no mandatory subscription, no complexity.

Our mission

To democratize access to professional ZPL tools for sellers of all sizes — from the beginner who just opened their store to operations processing hundreds of orders a day.

We believe no one should waste hours trying to understand printer code. You have a business to run.

What we've built

ZPLMaster Pro currently offers five free tools:

ZPL to PDF Converter — convert any ZPL code to 4×6 or A4 PDF in seconds
Shopee Image Fix — automatically fix oversized labels generated by Shopee
ZPL Syntax Validator — find and fix errors in your ZPL code line by line
Bulk Splitter — split files with hundreds of labels into individual files
Label Builder — create professional shipping labels without writing a single line of ZPL

Everything runs 100% in the browser. No label data is ever sent to our servers. Your operation is yours.

What's coming

We're building ZPLMaster Premium — an advanced toolset for higher-volume operations, including product labels with EAN barcodes, batch generation, and more.
