Questions
Is this a carrier label service?
No. PixlDocs renders the label document from your data; carrier booking and tracking numbers come from your carrier or your own system.
Which barcode types?
QR codes and common barcodes are available as smart elements; contact us if you want help if you need a specific symbology confirmed.
Can I print on thermal printers?
Render to a custom page size that matches your label stock.
Is it free?
Yes. PixlDocs is free for 1 year from 3 October 2026 while we work with early users. You can try a real example with no account; a free account starts with 100 credits, and you can ask us for more free credits when you run out.
