zeepler and Labelary

From Labelary's own pages, read on 2026-11-08. Check them for anything that matters to you; they may have changed.

• An online ZPL viewer, for viewing and designing labels and converting them to PNG or PDF. [1]
• A REST API that renders ZPL to PNG or PDF, and converts it to other label languages such as EPL and CPCL. [2]
• Renders at 6, 8, 12 and 24 dots per mm (152 to 600 dpi), at any label size up to 15 inches. [2]
• A ZPL linter, which reports problems in ZPL it renders. [2]
• Supports most ZPL formatting commands; ones it does not support are skipped rather than failing the render. [3]

It does this well. We use it ourselves: the ZPL in our how-to guides was checked by rendering it in Labelary.

• The public API is free for personal or commercial use, with no sign-up or API key. [2]
• Free use is limited to 3 requests a second and 5,000 a day. [2]
• Support on the free API is best effort. [4]
• Zero data retention is not offered on the free plan; it is on the paid ones. [2]
• Paid plans were listed at $90 and $228 a month, adding higher limits, a committed availability figure and support. [2]
• An offline version of the engine is licensed for local use. [4]

• You send POST /v1/zeeplify a JSON body: the values, and where each one goes. It answers ZPL as plain text, ready to send to a Zebra printer at 203 dpi.
• It makes text, Code 128, Code 93, EAN-13 and QR codes, on 3 × 1 and 4 × 2 inch labels.
• It does not render images. To see a label before printing, put the ZPL it returns into a viewer such as Labelary's.
• Request bodies are not stored or logged: a request is used to make the label and then discarded.

• You have ZPL and want to see it, or turn it into a PNG or PDF: Labelary.
• You have data and want ZPL without writing it by hand: zeepler.
• Both: make the label with zeepler, and preview it in Labelary while you design it. Bear in mind that a preview sends the label's content to Labelary, so for real customer data check its data-retention terms first.

• Raw ZPL or zeepler?: The same asset tag written by hand and made with one API call, and when writing ZPL yourself is the better choice.
