Free Barcode Generator
NToolHub’s Barcode Generator creates print-ready barcodes in the formats retailers and warehouses actually use, including CODE128, EAN-13, EAN-8, UPC-A, and ITF-14. It is ideal for small businesses labeling products, organizers printing tickets, or developers testing scanning workflows. Adjust bar width, height, and labels, then export a crisp vector SVG or PNG.

How to Use the Barcode Generator
- Enter the value to encode — digits for EAN and UPC, letters and digits for CODE128.
- Select the barcode format and adjust bar width, height, and the text label.
- Click “Generate Barcode” to render a live preview.
- Download the result as a scalable SVG or a PNG image.
Features
Ten symbologies are supported, from retail standards like EAN-13 and UPC-A to logistics formats like ITF-14 and flexible general-purpose CODE128. Invalid values are rejected with a helpful message so you never print a bad code. SVG export gives infinitely scalable vector output for professional printing, while PNG works everywhere else.
Benefits & Use Cases
Proper barcodes speed up checkout, inventory counts, and shipping — and professional labels make small products look established. Generating them yourself avoids per-label fees from printing services, and the vector SVG output keeps lines razor-sharp at any size, which scanners appreciate.
Tips
EAN-13 needs 12 or 13 digits and UPC-A needs 11 or 12; the check digit is calculated automatically. Keep quiet zones (the white margins) intact when placing barcodes in designs. Print a test copy and scan it with your phone before a full production run.
Frequently Asked Questions
Which barcode format should I use for retail products?
Use EAN-13 for most products worldwide, or UPC-A if you sell primarily in North America. Both encode the product number printed under the bars.
What is the difference between SVG and PNG downloads?
SVG is a vector format that stays perfectly sharp at any size, making it best for professional printing. PNG is a regular image file that works in documents, slides, and on the web.
Why was my value rejected?
Each format has strict rules. EAN-13 accepts only 12 or 13 digits, UPC-A accepts 11 or 12 digits, and formats like pharmacode accept numbers only. CODE128 is the most flexible choice.
Are the generated barcodes scannable?
Yes, provided the value is valid for the chosen format and the code is printed at a reasonable size with good contrast. Always test-scan before bulk printing.
