About Barcode Generator

Barcode Generator creates a scannable barcode image from text or a number, in your choice of Code 128, Code 39, EAN, UPC, ITF, or MSI. It's the tool for product labels, asset tags, and inventory stickers where a 1D barcode — not a QR code — is what your scanner expects. Output is a crisp SVG, so it stays sharp at any print size, and it's generated locally in your browser.

Common uses

  • Generate a Code 128 barcode for an internal asset tag or warehouse bin label
  • Produce a UPC or EAN barcode for a retail product before printing price stickers
  • Encode a shipment tracking number as an ITF barcode for a logistics label
  • Create Code 39 labels for a small-business inventory system that reads that symbology
  • Mint an ISBN barcode (EAN-13) for a self-published book's back cover
  • Batch out asset numbers as SVG so they print razor-sharp on a label printer

Frequently asked questions

Which barcode symbologies are supported?

Code 128, Code 39, EAN, UPC, ITF, and MSI.

What format is the generated barcode?

An SVG image, which scales to any size without pixelation — ideal for print.

What's the difference between this and a QR code?

These are 1D (linear) barcodes for product and asset labels; for URLs or longer text, a 2D QR code is usually the right choice — use the QR Code tool instead.

Does my input data get sent anywhere?

No. The barcode is rendered entirely in your browser; the text or number you encode never leaves your device.

Will the data validate against the format's rules?

Symbologies like EAN and UPC have fixed digit lengths and check digits; supply input that matches the format you pick so the result scans correctly.

QR Code
create

When you need to encode a URL or longer text, a QR code fits better than a 1D barcode.
SVG Optimizer
optimize

Trim the generated SVG before embedding it in a label sheet.
SVG to PNG
convert

Rasterize the barcode to PNG for tools that won't accept SVG.
QR Code
create

Generate a QR code image from text or a URL.
Favicon Generator
create

Generate a complete favicon set (PNG sizes + ICO + webmanifest) from any image.
Password Generator

Generate cryptographically random passwords with configurable character sets.
UUID Generator

Generate one or more random UUID v4 identifiers.
Lorem Ipsum
create

Generate placeholder Latin text (lorem ipsum) with configurable paragraphs and sentence length.
Color Harmony
create

Generate complementary, analogous, triadic, tetradic, split-complementary, and monochromatic color schemes from a base hex color.
SVG Optimizer
optimize

Optimize SVG files using SVGO. Removes comments, editor metadata, and rounds decimal precision.
Regex Visualize
inspect

Render a regex pattern as an SVG diagram. Each part of the pattern becomes a labeled box; groups nest, alternations stack vertically, repetitions show their quantifier underneath. Chains after regex-tester for the "what does this thing actually do?" hand-off.
