Which barcode format do you need?
The right format depends on where the barcode gets scanned, not on how it looks.
- Sold in shops: UPC-A in the US and Canada, EAN-13 in most other markets.
- Cartons and shipping cases: ITF-14 carries the carton number, and prints well on corrugated board.
- Batch numbers and expiry dates: GS1-128 for logistics labels.
- Internal use, such as stock or assets: Code 128 holds letters and digits in little space.
- Very small items: Data Matrix fits a lot of data into a small square.
- Links people open with a phone: QR Code.
Why the file type matters for print
Download SVG or PDF for print work. They are vector files, so bar edges stay sharp at any size, and they open in Illustrator and other design software. Use PNG for office documents and quick mockups. Resizing a PNG can blur the bars and stop them scanning.
Getting the size right
Barcodes are sized by the width of the narrowest bar, called the X-dimension. For EAN and UPC, GS1 sets 0.33 mm as 100%, with a range from 80% (0.264 mm) to 200% (0.66 mm). This tool warns you when a setting falls outside the GS1 range for that format. It also adds the blank quiet zone each format needs on either side, so keep other artwork out of that area.
What this tool does and does not do
It draws the barcode for the number you enter. It does not issue numbers: retail barcodes need a number licensed from GS1.
Scan a printed sample before a full run. Print quality, material and color all affect scanning, and only a barcode verifier gives a formal grade.

Common questions
Is this barcode generator really free?
Yes. There is no sign-up, no ads and no limit on downloads. Your files carry no watermark.
Will these barcodes work in a store?
The symbol will scan, but stores also need the number to be yours. Retail chains expect a number licensed from GS1, so get one before you print packaging.
Which colors can I print a barcode in?
Black bars on a white background are the safest. Dark blue or dark green on white usually works. Red bars do not, because many scanners use red light and cannot see them. Always test a printed sample.
Do you keep what I type?
No. The barcode is drawn in your browser, so the number or text is not sent to Asas Label. We only count which format was used and which file type was downloaded.
