Frequently asked questions about PZN7
Is the PZN7 generator really free?
Yes. You can create as many PZN7 barcodes as you like and download them as PNG or SVG – no registration, no watermark, commercial use included.
What resolution does the PZN7 barcode have?
PNG files are generated with adjustable module width and up to 600 DPI. For print we recommend the lossless SVG vector format which scales without any quality loss.
Is my data stored?
No. The barcode content is only processed to render the image and is not stored. We only count anonymously how often a barcode type is used.
Can I embed PZN7 barcodes in my website or software?
Yes. Every barcode has a stable image URL (see “Embed HTML”) which you can use in websites, label software or spreadsheets.
