Barcode Generator for CODE128, EAN, UPC, and Labels

Create CODE128, CODE39, EAN-13, EAN-8, and UPC-A barcodes directly in your browser with no sign-up or backend upload. Customize bar width, height, colors, and human-readable text, then export PNG or SVG instantly.

Barcode content and format

Choose a barcode standard, enter the value, and export clean PNG or SVG assets directly from the browser.

Barcode format

Flexible alphanumeric format for labels, internal tools, tickets, and general operations.

Encoded value

CODE128 is the most flexible option for mixed letters, numbers, and symbols.

Quick answer

A barcode generator turns a product code, SKU, order ID, or internal reference into a scannable static barcode image.

Use CODE128 for flexible internal labels, and use EAN or UPC formats when you need retail-style numeric barcodes.

Best inputs for barcode labels

Match the format to the scanner

Choose CODE128 for mixed text, CODE39 for uppercase legacy systems, and EAN or UPC for numeric retail identifiers.

Keep enough white space

Leave margin around the bars and prefer dark bars on a light background for reliable scanning.

Which format fits which job?

Pick the barcode standard based on where it will be scanned.

CODE128

Best default for internal operations, labels, shipping references, and workflow IDs.

EAN / UPC

Use these for retail product identifiers, packaging, catalogs, and point-of-sale systems.

CODE39

A practical option for older inventory, warehousing, and industrial labeling setups that expect uppercase codes.

Scan reliability tips

Barcode scanners are pickier about spacing and sharpness than QR codes.

Keep enough white space around the barcode and avoid placing borders or icons too close to the bars.

For print, SVG is the safer export because it stays razor sharp and avoids blur from scaling.

If scanners struggle, increase bar width slightly before increasing overall height. Thin bars are the first thing that tends to fail.

Common use cases

Static barcode images are useful when labels, scanners, and print assets need a simple encoded value.

Inventory labels

Generate CODE128 or CODE39 barcodes for SKUs, bins, shelves, rooms, and internal asset tags.

Product packaging

Create EAN-13, EAN-8, or UPC-A barcode assets for mockups, catalogs, and packaging workflows.

Shipping and operations

Encode order IDs, shipment references, ticket numbers, or handoff codes for operational labels.

Design and print prep

Export SVG for layout tools or PNG for quick documents, QA sheets, and label previews.

Barcode method and validation notes

Barcode output depends on the selected symbology and the characters it allows.

Assumption: CODE128

Use CODE128 for values like ORDER-1024 or SKU-A17 because it supports letters, numbers, and symbols.

Example: EAN / UPC

Retail formats are numeric and include check-digit rules. If the check digit is omitted, the generator can calculate it.

Limitation

The image is static. It does not register products, reserve GS1 prefixes, or connect the code to a tracking backend.

Frequently asked questions

Is this a free barcode generator with no sign-up?

Yes. It creates static barcode images in your browser without an account, upload, or backend processing.

Can I generate CODE128 barcodes for labels?

Yes. CODE128 is a strong default for internal labels because it supports mixed letters, numbers, and symbols.

Can I use this barcode generator for product packaging?

Yes, but make sure you choose the right retail format. EAN-13, EAN-8, and UPC-A are the relevant formats for packaging and product identifiers. SVG export is strongly recommended for production layouts.

Why do some barcode formats accept only digits?

Retail formats like EAN and UPC are standardized numeric symbologies. Their structure is defined by scanning systems and check-digit rules, so they cannot accept arbitrary text the way CODE128 can.
