Frequently Asked Questions
What is Code 128? +
Code 128 is a high-density linear barcode symbology. It can encode all 128 ASCII characters and is widely used in shipping, packaging, and inventory management. It's one of the most common barcode formats in use today.
What characters can I encode in a Code 128 barcode? +
This tool uses Code 128B, which supports all standard printable ASCII characters including uppercase and lowercase letters, numbers, punctuation, and spaces (ASCII 32-127).
Can I download the barcode as an image? +
Yes, click the 'Download PNG' button to save the barcode as a PNG image file. The downloaded image will match the width and height settings you've configured.
Is there a maximum length for the barcode text? +
While there's no strict character limit, very long text produces very wide barcodes that may be impractical to scan. For best results, keep your input under 50 characters. The barcode width adjusts automatically based on content length.
Will this barcode scan correctly? +
Yes, the barcodes generated by this tool follow the Code 128B specification with proper start codes, checksums, and stop patterns. They will scan correctly with any standard barcode reader that supports Code 128.
