Using Barcode Generator for websites and apps

Embedding a barcode from Barcode Generator into a website or mobile app, the right way. Browser-based, free, no signup, runs entirely on your device.

Tool:Barcode Generator

Generating a barcode sounds like it should require an app — and historically it did. Barcode Generator runs the same thing in your browser tab, with one tap and no signup.

Barcode Generator for websites and apps

Embedded in a digital interface, a barcode is just a graphic. Pick the format that fits the medium: SVG for web (infinite-scaling, crisp at any zoom), PNG for fallback compatibility.

How to embed

  • SVG inline — paste the Barcode Generator SVG output into your HTML for instant rendering with zero requests
  • PNG with srcset — generate at 2× the display size, let the browser scale down for retina
  • Lazy-load below-fold barcodes — use the loading="lazy" attribute when there are many on the page

Everything happens locally in your browser — your file never leaves your device.

Frequently asked questions

Will my barcode work after Barcode Generator shuts down?

Yes — once generated, a barcode is a standalone artefact. It doesn't depend on Barcode Generator continuing to exist.

Does Barcode Generator store my generated barcode?

No. Barcode Generator generates everything in your browser; nothing is uploaded, saved, or sent.

Can I customize the barcode's appearance?

Yes — size, color, error-correction, margin, and optional logo overlay are all supported.

Can I generate barcodes in bulk?

Yes — drop a list of inputs and Barcode Generator runs them all in sequence, packaged into a ZIP for download.
