How to make a barcode
- Pick a barcode type. Each one shows an example value.
- Type your value. For EAN and UPC, leave out the last digit and it is calculated for you.
- Adjust bar width and height, then download SVG for print or PNG for documents.
Printing barcodes that scan
- Keep dark bars on a light background; red bars are invisible to most scanners.
- Leave a quiet zone (empty space) on both sides of the bars.
- Don't squash the height too much, and test with a phone scanner app before printing a batch.

Frequently Asked Questions
Which barcode type should I use?
For products sold in shops, use EAN-13 (most of the world) or UPC-A (US and Canada) with a number from GS1. For your own labels, inventory, tickets or asset tags, Code 128 is the most flexible: it holds letters, numbers and symbols in a compact code.
Can I make my own EAN or UPC number?
You can make the barcode image for any number, but retailers and marketplaces like Amazon require numbers licensed from GS1 (or your country's GS1 office, such as GS1 Bangladesh). Made-up numbers can clash with real products.
What is the check digit?
EAN and UPC codes end with a digit calculated from the others, so scanners can catch misreads. Type 12 digits for EAN-13 (or 11 for UPC-A) and it is added for you; if you type all 13, the tool checks it.
PNG or SVG for printing labels?
SVG for print: it scales to any size without blurring, so bars stay sharp. PNG for documents and spreadsheets; choose a larger scale for print.
Is anything uploaded?
No. Barcodes are drawn in your browser.
