What is Barcode?
A barcode generator for the most common 1D symbologies. Pick a format, enter the value, and get a standards-compliant barcode image.
How it works
The barcode is drawn locally with jsbarcode — no server round-trip — and exported as either SVG or PNG.
- Enter your input. Type or paste your input into the field above — the tool responds instantly.
- Review the result. Output updates live as you type. Everything runs entirely in your browser.
- Copy or download. Use the Copy button to grab the result, or Download to save it as a file.
Examples
Label and packaging codes
Generate a Code 128 or EAN-13 barcode from a value, ready to print on labels, price tags, or packaging.
Common mistakes
Wrong symbology
EAN-13 is the retail standard for products; Code 128 is general-purpose. Choosing the wrong type can fail downstream scanners.
Frequently asked questions
Does it add a check digit?
For EAN-13 the check digit is computed automatically; Code 128 includes its own internal checksum.
What output formats are available?
SVG and PNG, at the resolution and height you choose.
