Edit the ZPL, pick a format, hit Convert.
Needs an API key — the paid tier takes one step.

/ 30 lab

Beyond the editor

When a text box stops being enough.

The playground converts what you paste. Designer is where you build the label itself.

Open Designer

Reference

Every ZPL command, at hand.

217 commands with signature and description — and the 31 this engine renders marked as such.
Canvas

Place it, don’t count it.

Drag text, barcodes, QR codes and boxes instead of working out dot coordinates.
Output

Render and download, in place.

One button renders the label. One button saves it as PDF, SVG or PNG.
Workspace

Room for more than one label.

Tabs, a section list and a searchable palette. Guests and Free accounts get one tab.

Questions

While you are here.

The ones that come up most in the editor. Plans and billing live on the pricing page.

Why did I get one label back?

Only PDF · all labels returns more than one. PDF, SVG and PNG each render a single label — the first one in your ZPL. So a three-label paste converted as PDF gives you label 1, not all three.

Output formats

Do I need an API key?

No. This playground renders locally with WebAssembly. API keys are only needed when you call the hosted conversion API directly.

API keys

Why is Resolution greyed out?

Only PNG has one. PDF and SVG are vector — they carry no pixel grid, and the API refuses ?dpi= on them outright. 203 DPI is the Zebra printer default; 600 DPI is roughly 8× the bytes.

Resolution

My ZPL was rejected — now what?

The engine renders the thirty commands real label files use. Anything outside that set returns 422 naming the command, the label it sat on and its byte offset, so you can find the one line at fault. Labels must be complete, uppercase ^XA … ^XZ frames.

Supported ZPL

How much ZPL can I paste?

Guests and Free accounts convert up to 30 labels and 512 KiB per request — the counter under the editor shows both as you type, and turns red before you spend a request that would be refused. Paid plans lift the ceiling.

Limits

Does the playground use my quota?

No. Playground renders happen in this browser and do not call the hosted API. Direct API calls still count labels against your plan.

How labels are counted

Is my ZPL sent anywhere else?

No. The editor's contents stay in this tab while the local renderer converts them. Direct API calls you make outside the playground still send ZPL to the conversion endpoint.

Authentication

Can I build a label from scratch here?

No — the playground converts ZPL you already have. Designer is the other half: drag text, barcodes and boxes onto a canvas and it writes the ZPL for you, which you can paste back here or send straight to the API.
