Advanced (GS1, checks, profiles, retail add-ons, supply-chain carrier)
Code 93 Extended maps ASCII through shift characters; the scanner read-back must reproduce the original text.
Style (readable text, bar height, export size)
Bar height stretches bars vertically, which scanners ignore (only horizontal timing matters). The SVG download keeps the engine's exact geometry.

- Code 93 Extended on work-order paperwork for line-side scanning
- Code 93 Extended proofs exported as PNG for quick sharing
Shape
Pros
- Code 93 Extended tolerates industrial printers, labels and badge stock.
- Case folding, padding and check rules are explained before encoding.
- PNG and SVG exports cover both quick sharing and print.
- The self-verify readout shows exactly what a scanner will observe.
Cons
- Code 93 Extended is wider per character than 2D codes for long payloads.
- Dense narrow bars demand close, steady photography when verifying.
- Damaged or smudged labels lose characters with no error correction.
- Colored or low-contrast prints scan poorly.
Form requirements
- Enter Code93 Ext!.
- ASCII characters 0–127, up to 80 characters; Code 93 checks are inherent.

How it works
Three steps, all on your device.
The same engine that reads barcodes writes them — every symbol is decoded again before you see it.
