What the tool does

The Barcode Generator produces real, scannable barcodes in three standard formats:

• EAN-13 — the standard retail product identifier used on consumer goods worldwide.
• EAN-8 — a compact version for short retail product codes.
• Code 128 — a flexible alphanumeric format used in logistics, inventory, shipping labels, and internal systems.

One thing that sets this tool apart from a plain label maker: it keeps the scanner-critical barcode zone clean while adding decorative artwork above it. That makes the output look distinctive in mockups, packaging concepts, demos, and product presentations — while the barcode itself stays practical and scannable for testing.

For EAN values, you can enter the number with or without the checksum digit. When possible, the checksum is added automatically so the barcode library receives a valid value.

How to use it

1. Open the tool at the link above.
2. Pick a format — EAN-13 for retail products, EAN-8 for short retail codes, or Code 128 for inventory, shipping, and internal labels.
3. Enter your value — the product code, tracking number, or label text. For EAN-13, type the 12 digits (or 13 if you already have the checksum); the tool completes it automatically where possible.
4. Preview the barcode — the preview is SVG-based and updates as you type. The scannable zone stays at the bottom, with the decorative artwork kept above it.
5. Download or copy — export the full styled preview as an SVG file, or copy the SVG markup straight to your clipboard for use in a design tool, web page, or document.

That's it — the whole process takes under a minute.

Practical tips

1. Choose the format by use case. EAN-13 is the safe default for anything sold at retail. Code 128 is the better pick when your value contains letters or you need longer identifiers — it's built for alphanumeric warehouse and shipping codes.
2. Respect the quiet zone. Barcodes need blank space around them to scan reliably. Don't place text, borders, or other graphics against the edges of the scan zone when you lay the barcode into a design.
3. Test before you print in bulk. For anything going to commercial printing, print one first and scan it with a real scanner or a phone app. Check final size, contrast, paper stock, and scanner hardware before producing a large batch — especially at small sizes.

FAQ

Are these barcodes actually scannable?

Yes. The barcode zone is generated with JsBarcode using standard formats, and the decorative artwork is kept away from the bottom scan zone so it doesn't interfere with reading.

Which barcode format should I choose?

Use EAN-13 for most retail product codes, EAN-8 for short retail codes, and Code 128 for flexible alphanumeric inventory or shipping labels.

Can I download the barcode as SVG?

Yes. The tool exports the full styled preview as SVG and can also copy the SVG markup to your clipboard.

Do I need the checksum digit for EAN codes?

No. Enter the value with or without it — when possible, the checksum is added automatically so the barcode library receives a valid value.

Privacy note

The tool runs 100% in your browser. Nothing is uploaded — your product IDs, campaign codes, warehouse labels, and internal tracking numbers never leave your device. The SVG preview and download are generated locally on your machine.
