Barcode Generator

Barcode Generator creates standard 1D barcodes — CODE128, CODE39, EAN-13, EAN-8, UPC, ITF-14 and more — from any value you enter. Toggle the human-readable text and download a clean, scalable SVG.

Barcodes are rendered entirely in your browser, so the values you encode are never uploaded.

How to use Barcode Generator

  1. 1

    Enter a value

    Type the data to encode — a product number, SKU or reference code.

  2. 2

    Choose a format

    Pick a barcode symbology. Each has its own rules for length and allowed characters.

  3. 3

    Download SVG

    Toggle the caption if you like, then download a scalable SVG for labels or print.

Which barcode format should I use?

CODE128 is the most versatile choice: it encodes any ASCII characters and is common in shipping and logistics. CODE39 is older and simpler, encoding letters, digits and a few symbols. For retail products, EAN-13 and UPC-A are the standard formats printed on packaging worldwide, while EAN-8 suits small packages.

ITF-14 is used on shipping cartons, MSI on inventory and warehouse labels, and pharmacode in pharmaceutical packaging. Pick the format your scanner or downstream system expects.

Why SVG output?

Barcodes here are rendered as SVG, a vector format that stays perfectly sharp at any size. That matters for barcodes because blurry or low-resolution bars are a common cause of failed scans.

An SVG can be scaled up for a large carton label or down for a small product tag without losing crispness, and it drops cleanly into design tools, documents and print workflows.

Frequently asked questions

Why does my value show an error?
Each format has strict rules. EAN-13 needs 12–13 digits, UPC needs 11–12 digits, and others restrict the characters allowed. Check the format's requirements or switch to CODE128, which accepts any text.
Can I print these barcodes?
Yes. Download the SVG and place it in your label or document. Because it is vector, it stays sharp at any print size.
Is my data uploaded?
No. Barcodes are generated locally in your browser and the encoded value never leaves your device.
