Evoke AI's free Barcode Generator turns a product number, SKU, or any text into a scannable PNG — right in your browser. Pick a format (Code 128, Code 39, EAN, or UPC), choose With logo or No logo, preview instantly, and download without creating an account. Nothing is uploaded to a server.
What is a barcode?
A barcode stores a short string — usually a product ID — as a pattern of black lines and spaces. A scanner reads that pattern and looks up the matching item in a POS, warehouse, or inventory system. Barcodes are faster and more accurate than typing numbers by hand at checkout or on the warehouse floor.
With logo vs without logo
With logo places a small Evoke lockup above the bars on a white pad so the code still scans. No logo exports a clean barcode with no brand mark — useful for client labels, packaging, or designs where you want a plain code. Both options are free to preview and download.
Which barcode format should you choose?
- Code 128 — letters and numbers together; best for internal SKUs, shipping, and warehouse labels
- Code 39 — simple alphanumeric format still common in manufacturing and government
- EAN-13 — 13-digit retail codes used internationally (Europe and beyond)
- UPC — 12-digit retail codes used mostly in the US and Canada
If you only need internal tracking, Code 128 is usually the easiest choice because it accepts almost any SKU. For store shelves and major marketplaces, you typically need an official UPC or EAN number from GS1 — the generator creates the image; GS1 issues the number.

How does barcode generation work?
The tool encodes your string with the rules for the format you chose, draws the bars and human-readable text onto a canvas, and exports a PNG. Optional logo branding is stamped above the bars so scanners still see a full quiet zone. Everything runs on your device — no file leaves the browser.

When should you use this tool?
- Before printing product labels, shelf tags, or shipping stickers

- When you want internal inventory codes without buying hardware software
- When you need a one-off barcode without a SaaS account
Tips for scannable results
Print large enough that the bars stay sharp. Keep high contrast (black on white). Leave blank white space (quiet zone) around the code. Do not stretch the image unevenly. Test-scan one label before a bulk print run. For retail UPC/EAN, use the official GS1 number assigned to your product.
A barcode is only as useful as the number behind it — keep SKUs unique, and test-scan before you print in bulk.
Barcode generator vs QR code generator
A traditional barcode is a 1D code that stores a short product ID for checkout scanners. A QR code is a 2D grid that can hold a full URL or longer text for phone cameras. Use the Barcode Generator for retail and inventory labels. Use the QR Code Generator when you need links, Wi‑Fi tips, or richer payloads. Evoke AI offers both as free on-device tools.
Do you need an official UPC from GS1?
If you sell through major retailers, Amazon, or Google Shopping, you generally need a licensed UPC or EAN from GS1. This generator draws the barcode image; it does not register the number to your business. For warehouse tags, asset labels, and internal stock only, any unique Code 128 string is fine as long as your system stays consistent.
Frequently asked questions
Is it free? Yes — With logo and No logo downloads are free in your browser.
Do I need an account or signup? No.
What format should I use? Code 128 for internal SKUs; UPC or EAN for retail products with a licensed number.
Why won't my printed barcode scan? Check size, contrast, quiet zone, and stretch. Test one label first.

Can I make QR codes here too? Use Evoke's separate QR Code Generator for 2D codes from text or images.
