Barcode Generator
Generate a scannable Code 39 barcode from text or numbers, right in your browser.
TOOLVYRA123
This tool generates a Code 39 barcode, one of the most widely supported barcode formats, readable by nearly any barcode scanner without special configuration. Code 39 supports uppercase letters, numbers, and a small set of symbols including a hyphen, period, space, dollar sign, slash, plus sign, and percent sign.
Type your text into the input field and a scannable barcode appears instantly below, updating as you type. Lowercase letters are automatically converted to uppercase, and any unsupported character is simply skipped, since Code 39 cannot represent it. Click Download PNG to save the barcode as an image ready to print or paste into a label or document.
This is useful for generating a quick barcode for inventory labels, asset tags, library books, or any internal tracking system, without needing dedicated barcode software.
What characters does Code 39 support?+
Uppercase letters A through Z, digits 0 through 9, and the symbols hyphen, period, space, dollar sign, slash, plus sign, and percent sign.
Why were some of my characters removed?+
Code 39 cannot represent lowercase letters or symbols outside its supported set, so unsupported characters are automatically skipped.
Will any barcode scanner read this?+
Code 39 is one of the most widely supported barcode formats and is readable by the vast majority of barcode scanners without special setup.
Is my text sent to a server?+
No. The barcode is generated and rendered entirely in your browser.
