Free Barcode Generator Online: Create Any Barcode in Seconds

Barcodes are everywhere — on every product you buy, every box you ship, every ticket you print. If you need to create one, you do not need expensive software or a desktop application. A good free barcode generator online gets the job done in seconds, right in your browser.

This guide explains the main barcode types, when to use each, and how to generate one free using QRhubly's barcode generator — no sign-up required.

What is a barcode and who needs one?

A barcode is a visual pattern that encodes data — usually numbers or short text — so a scanner can read it instantly. The scanner bounces a beam of light off the stripes and translates the result back into data.

Who uses them:

• Small businesses and retailers — labelling products for point-of-sale systems
• Warehouse and inventory teams — tracking stock without manual entry
• Shipping and logistics — carrier labels (UPS, FedEx, USPS all use 1D barcodes)
• Event organisers — ticket barcodes scanned at the gate
• Libraries and schools — asset tracking for books and equipment

If you have ever stuck a label on a product or printed a shipping label, you have worked with a barcode.

Types of barcodes explained

Not all barcodes are the same. Different industries settled on different formats for specific reasons. Here is a quick reference:

Barcode type	What it stores	Common use case
Code 128	Any ASCII character, up to ~48 chars	Shipping labels, inventory, logistics
EAN-13	13 digits	Retail product labels (Europe, global)
UPC-A	12 digits	Retail product labels (US/Canada)
Code 39	Alphanumeric	Automotive, government, industrial
EAN-8	8 digits	Small product packaging
ITF	Even-number digits	Outer cartons, logistics
QR code	URLs, text, contact info, and more	Mobile, marketing, contactless

Quick guide to picking the right type:

• Selling products in stores? Use EAN-13 (global) or UPC-A (US/Canada). You will need a registered GS1 company prefix so the number is globally unique.
• Internal tracking or shipping? Code 128 is the default — flexible, widely supported, and reads fast from almost every scanner.
• Government or industrial labelling? Code 39 is the old standard that many legacy scanners still expect.
• Linking to a URL or sharing info with a phone? That is a QR code's job — see the section below.

How to generate a barcode free

QRhubly's barcode generator supports all the major 1D formats plus QR codes, and it runs entirely in your browser. Here is how to use it:

1. Open the tool — go to qrhubly.com/barcode-generator. No account needed.
2. Choose your barcode type — pick from Code 128, EAN-13, UPC-A, Code 39, EAN-8, ITF, and more.
3. Enter your data — type the number or text you want encoded. A live preview updates as you type.
4. Adjust settings if needed — change the scale, bar height, or toggle the human-readable text below the bars.
5. Download — save as PNG for labels and documents, or SVG if you need a vector file for professional print production.

The whole thing takes under a minute. No software to install, no email address required.

Printing tips for reliable scanning:

• Keep the barcode at least 25 mm wide when printed
• Use high contrast — black bars on white background is always safest
• Leave a quiet zone (blank margin) on both sides, at least the width of 10 thin bars
• Test with a scanner or phone app before mass printing

Barcode vs QR code — which should you use?

This comes up constantly. Here is the short version:

Use a 1D barcode (Code 128, EAN, UPC, etc.) when:

• Your scanner or POS system expects a traditional striped barcode
• You are labelling products for retail (EAN-13/UPC-A)
• You are printing carrier shipping labels
• The device reading it is a dedicated barcode scanner, not a smartphone

Use a QR code when:

• The reader is a smartphone camera
• You need to encode a URL, contact details, WiFi credentials, or longer text
• You want something people can scan without specialist hardware
• You are running a marketing campaign, digital menu, or event check-in

The biggest practical difference is capacity. A Code 128 barcode holds a few dozen characters. A QR code holds thousands of characters. If you need to link someone to a website, use a QR code. If you need to label products for a checkout scanner, use a 1D barcode.

QRhubly's barcode generator handles both in the same tool. Pick the type that fits your use case and generate it in seconds.

Common questions

Can I use these barcodes commercially?
Yes. Static barcodes generated with QRhubly are yours to use however you like — on product labels, internal documents, shipping labels, or any commercial application. No watermarks, no licence restrictions.

Do I need a GS1 number?
If you are selling through major retailers, yes. EAN-13 and UPC-A barcodes on retail products should use a registered GS1 company prefix so the number is globally unique. For internal inventory, warehouse tracking, or non-retail use, you can assign any number you choose.

What format should I download?
PNG is fine for most uses — labels, Word documents, online listings, and print-at-home sheets. Download SVG if you need to resize without quality loss or send the file to a commercial printer.

Is there a limit on how many I can generate?
No. The barcode generator is completely free with no daily limits. Generate as many as you need.

What about dynamic QR codes?
Static QR codes and all 1D barcodes are free forever. Dynamic QR codes — where you can edit the destination URL after printing and see scan analytics — are a Pro feature with a 7-day free trial.
