ZPL em PDF vs Labelary

Labelary is the category reference: the ZPL viewer nearly every developer knows, with a free REST API that became the de facto integration standard. ZPL em PDF was built with that model as inspiration, with two base differences: a Portuguese-first UI and rendering that happens in your browser — label code is never sent to any server.

Where Labelary is strong

You can't discuss ZPL without Labelary: it's the reference engine others measure against, with huge command coverage, an actionable linter and inline documentation in the viewer.

The free hosted API (5,000 requests/day, no signup) and cross-language conversions (EPL, IPL, DPL, SBPL, PCL) are real strengths a browser-only tool doesn't replace.

Where ZPL em PDF wins

Privacy: with Labelary, every label you preview passes through their server — and the plans table lists data retention up to 60 days on the free tier. Here, rendering is local and nothing is sent.

Portuguese: UI, guides and support built around Brazilian marketplace workflows (.txt files from Mercado Livre, Shopee, Magalu; the 4x6 label).

No counter on manual use of the site — there are no requests to meter.

If you use the Labelary API

Our engine was built with Labelary API compatibility as a requirement (same /v1/printers/{dpmm}dpmm/labels/{w}x{h}/{index}/ URL shape). The hosted API is in preparation — once live, migrating will mean changing one URL. Until then, for server-to-server integrations, Labelary's free API remains a good choice.

Questions

Frequently asked questions

Is Labelary free?

Yes — the viewer is free and the API has a generous keyless free tier (3 req/s, 5,000 requests/day). Paid plans (US$90 and US$228/month) raise limits and add SLAs. The difference here isn't price: it's language and where rendering happens.

Does ZPL em PDF use Labelary under the hood?

No. The rendering engine is our own and runs in your browser — no request is made to Labelary or any other server during conversion.

Where does my ZPL stay private?

With ZPL em PDF, the code never leaves your machine. Labelary renders server-side; their plans page lists data retention up to 60 days on the free tier and “never” on paid tiers.

When will the compatible API be available?

The engine and the Labelary-compatible surface already exist; the public hosted API is in preparation. Meanwhile, use of the site has no counter.
