Free barcode generator for labels

Most free barcode generators only give you a PNG. You need a free barcode generator for labels that sets a real size and DPI, then prints a sticker that scans. That's this, in the browser. No signup.

What you can generate

• CODE128 for SKUs, bins, and serials. Most flexible.
• UPC-A for US retail product stickers you already own a number for.
• EAN-13 for international retail numbers you already own.
• QR for URLs, WiFi, and asset links.

How to use a free barcode generator for labels

1. Open https://app.mylabelmaker.com. No signup. Set the size (2x1, 2.25x1.25, 3x2) and the printer DPI.
2. Add a native barcode, not a downloaded screenshot.
3. Add the human-readable text. Leave quiet zones on both sides.
4. If you have a list, load Excel with {{barcode}}. Guide: Excel barcodes.
5. Print with Browser Print, or download PNG or PDF. Scan one before the run.

Why PNG generators fail on thermal

• Wrong DPI: soft bars that will not scan
• Scaling in Word or Canva wrecks bar width
• No quiet zone control
