Question 1

How do I upload my first ZPL label?

Accepted Answer

Navigate to Dashboard → Label Converter. Click the upload area or drag-and-drop your .zpl file. The label will be instantly converted and displayed as a preview. You can then export it as PDF, PNG, or SVG.

Question 2

What file formats does Zentralabel accept?

Accepted Answer

Zentralabel accepts .zpl and .txt files containing ZPL (Zebra Programming Language) code. This is the standard format exported by Amazon Seller Central, Vendor Central, ShipStation, and most shipping platforms.

Question 3

What is the Label Enricher?

Accepted Answer

The Label Enricher allows you to overlay additional data — like SKUs, bin locations, quantities, and custom text — directly onto your shipping labels. Upload a ZPL file and a CSV file, configure matching rules, and Zentralabel merges the data automatically.

Question 4

How do I process multiple labels at once?

Accepted Answer

Upload a ZPL file containing multiple labels (separated by ^XA/^XZ blocks). Zentralabel automatically splits them into individual labels. You can then enrich all of them and export the entire batch as a single PDF or a ZIP of PNGs.

Question 5

What counts as a processed label?

Accepted Answer

Each label that is successfully converted or exported counts as one processed label. Preview renders and failed conversions are not counted against your limit. SVG exports use 2 labels from your monthly limit per file.

Question 6

Do unused labels roll over to the next month?

Accepted Answer

Monthly label allowances reset at the beginning of each billing cycle. Purchased top-up volume never expires and carries forward indefinitely.

Question 7

How do I generate an API key?

Accepted Answer

Go to Dashboard → API Keys and click 'Create Secret Key'. Name your key and save it immediately — for security, we only show the full key once. API access requires the Vendor plan or higher.

Question 8

Is my data encrypted?

Accepted Answer

Yes. All data is encrypted in transit using TLS 1.3. We follow industry-standard security practices.
