About this tool
Everything Free Barcode Gen does happens on your own device. Free Barcode Gen encodes your text into a QR matrix locally with an open-source library and renders it to a canvas.
Higher error-correction levels (Q or H) survive damage or partial cover at the cost of denser modules; level M suits most links. Nothing you enter is uploaded, and it keeps working offline once the page has loaded.
