# Code 93 Barcode Generator

Generate a Code 93 barcode from digits, capital letters and the symbols of Code 39 in a more compact and more secure form. The tool adds both mandatory check characters automatically and draws the barcode as a PNG image or an SVG file. Logistics teams and label designers can set the scale, the bar height and whether the text is printed below the bars.

## Frequently asked questions

### Which characters can I encode with Code 93?

This tool encodes the standard Code 93 set: digits 0 to 9, capital letters A to Z, space and the symbols - . $ / + %. Lowercase letters and other symbols are refused. Up to 60 characters are accepted.

### Are the check characters added for me?

Yes. Code 93 requires two check characters, called C and K, calculated with weighted modulo 47 sums. The tool always adds both, so scanners accept the barcode without extra configuration. They are not printed in the human readable text.

### How is Code 93 different from Code 39?

Code 93 encodes the same characters as Code 39 but uses only 9 modules per character, so the barcode is considerably shorter. Its two mandatory check characters also make misreads less likely. Code 39 remains more widespread in older systems.

### Should I download the Code 93 barcode as PNG or SVG?

Choose SVG for print work, packaging artwork and anything you scale later, because the bars stay sharp at every size. Choose PNG for documents, web pages and label software that only accept raster images. The PNG has a white background and the SVG draws a white background rectangle, so both scan on any page color.

### What does the scale setting do?

The scale from 1 to 10 multiplies the width of every bar and space, with 3 as the default. A larger scale makes the barcode easier to read from a distance but also wider.

### Can I change the bar height?

Yes, from 5 to 50 millimeters. Leave the field empty for the default height of about 25 millimeters.

### Is the text printed under the bars?

By default, yes. Turn off the human readable text option if you only want the bars.

### Do all scanners read Code 93?

Most modern scanners decode Code 93, but some are shipped with it disabled. If yours does not read the barcode, enable Code 93 in its settings or use Code 128, which every scanner reads by default.

### Why was my input rejected as too large?

The image may be at most 4000 pixels on a side. A long text at a high scale can exceed that width, so lower the scale or shorten the text.

### Is my text stored?

No. It is used only to render the barcode image and is not saved.
