## What is Barcode Generator?

Barcode Generator is a free online utility from Farvixo that lets you generate CODE128, EAN and UPC barcodes. Everything is generated locally in the browser, so nothing is uploaded or retained. Free forever, unlimited, and no account is needed to use it.

## Use cases

- A one-off task where installing software would be overkill
- Generating something quickly on a phone, away from your desk
- Producing an asset for print, a slide or a page
- Anyone who needs a reliable result without ads or sign-up walls

## Tips

- Test the output in its real destination before producing it in bulk.
- Where a size is offered, pick the largest you may need — scaling down keeps quality, scaling up does not.
- The page works offline once loaded, which is useful on an unreliable connection.

## Common problems

- **The output does not work where you pasted it** — The destination expects a different format or encoding. Check what it accepts and re-generate accordingly.
- **The result is too small to use** — Increase the size or resolution before generating rather than enlarging the file afterwards.
- **Nothing happens when you click** — A required field is empty, or a browser extension is blocking the script. Try a private window with extensions disabled.

## FAQ

### Which barcode type do I need?

CODE128 for internal use — it accepts any text and any length. EAN-13 for retail products sold in Europe and most of the world, UPC-A for North America. Retail codes are not free-form: they must be officially assigned to you.

### Can I invent my own EAN or UPC number?

For a barcode you scan yourself, yes. For anything sold in shops, no — retail codes are issued by GS1, and an invented number will either fail validation or collide with a real product. Use CODE128 for internal labelling instead.

### Why will my printed barcode not scan?

Almost always resolution or quiet zone. Print at actual size rather than scaling, and leave clear white space either side of the bars — scanners need it to find the code. Also avoid printing onto a coloured or reflective background.

### Is the barcode good enough for print?

Yes. Output is high resolution and suitable for labels and packaging, not just screen display. There is no watermark and no limit on how many you generate.

### Can I download the barcode as a vector?

SVG output is available, which scales to any size without softening. Use it for print; PNG is fine for screen and for systems that cannot accept SVG.
