Open the free label maker: app.mylabelmaker.com. No signup. Design the label, then print to a Zebra or download PNG, PDF, or ZPL.

Warehouse inventory sample from the free label maker
This is the warehouse inventory template in the free app. Open it and swap in your own text.

"My barcode will not scan" is the warehouse version of a 404. Use a native barcode, not a phone photo. Leave a quiet zone, print at 203 or 300 DPI on the actual stock size. Open the free label maker to do it now.

Good to know: A pretty Canva barcode image is often too soft for 203 DPI thermal. Rebuild it native here.

How to make scannable barcodes online

  1. Open the inventory barcode template. No signup.
  2. Set the size to the sticker or roll you actually have.
  3. Add a native CODE128, UPC, or EAN, plus the name that belongs on this label.
  4. Print on a thermal printer or download PNG or PDF. Optional: load Excel or Google Sheets for a whole list.

Checklist

If it still fails

Clean the printhead, raise darkness, slow the speed. Related: barcodes not scanning, print too light.

Print a whole list from Excel or Google Sheets

Put each SKU, name, or code in its own row. In the app, map a column into text, a barcode, or a QR code. Preview one row, then print the stack. Guide: mail merge labels.

Print or save

Got a Zebra? Print with Browser Print at the printer's DPI. No Zebra? Print from this computer, or download PNG, JPG, SVG, PDF, or ZPL. Save JSON if you want to open the layout again later.
