Validated Code 128 or Code 39 labels in PNG, ZIP, A4, or Letter format
High-resolution PNGs preserve quiet zones and bar proportions. PDF sheets use fixed cells so browsers never stretch the barcode image.
- Lowercase or unsupported symbols when Code 39 is selected
- Duplicate SKUs creating duplicate filenames
- Printing with Fit to page instead of 100% scale

Questions before you print
Should I use Code 128 or Code 39?+
Code 128 is compact and supports more characters. Code 39 is common in industrial systems but has a smaller character set.
Can this make UPC or EAN retail codes?+
No. Those identifiers require controlled allocation, strict lengths, and check digits; this tool focuses on internal Code 128 and Code 39 workflows.
Will the printed barcodes scan?+
Exports preserve a white quiet zone, dark bars, and fixed proportions. Printer quality and scaling still matter, so test one sheet before a large run.
