Code 128 Barcode Generator

Q: Can I hide the digits below the bars?

Yes. Turn off 'Show human-readable text' under Appearance to keep bars only, or leave it on for manual checking.

Q: My barcode won't scan — what now?

Usually it's too small or low-contrast. Increase the module width, keep dark bars on a white background, download at higher resolution and leave enough quiet zone on both sides.
