What is Barcode generator?
Barcode Generator — Create barcodes free: Code 128, QR codes, EAN-13, UPC-A and Data Matrix. Type your data, pick a symbology and download the barcode as SVG — no signup.
Barcodes are rendered by the bwip-js open-source engine (metafloor/bwip-js, MIT), which validates your data against each symbology's spec — character set, length, and check digits — and draws the bars directly to SVG markup, all in your browser with nothing uploaded. Honest limitations: fixed-length retail symbologies reject bad data instead of guessing (EAN-13 needs 12 or 13 digits, UPC-A needs 11 or 12); the SVG is print-ready, but always test-scan a printed copy before mass printing.
