Frequently asked questions
What barcode format does this generate?
The generator creates Code 128 style barcodes, which can encode all ASCII characters and are widely used in shipping, retail and logistics.
Can I use the barcode commercially?
Yes — the generated barcode image is yours to use in any project, commercial or otherwise.
What is the maximum text length?
There is no strict limit, but longer text produces wider barcodes. For practical scanning, keep the text under 20 characters and ensure the printed barcode is at least 2.5 cm wide.
Can scanners read these barcodes?
The barcodes are generated using a simplified rendering algorithm for visual reference. For production use in retail or logistics, use a certified barcode library to ensure scanner compatibility.
