The barcode generator by Get-Tools is a completely free online tool that works directly in your browser without any installation or registration required. It allows you to create over 10 different types of professional barcodes including QR Code, CODE128, EAN-13, UPC-A, and many more, with full customization of colors, dimensions, and fonts. Download your barcodes as high-resolution PNG or editable vector SVG files. Whether you are an online store owner, warehouse manager, or packaging designer, this tool covers all your barcode creation needs.
Supported Barcode Types
The tool supports a comprehensive range of global barcode standards covering all commercial, industrial, and marketing needs:
- QR Code -- A two-dimensional barcode capable of storing text, URLs, phone numbers, and business card information. Widely used in marketing campaigns, posters, advertising flyers, and digital restaurant menus. Supports error correction level M for reliable scanning even with partial damage.
- CODE 128 -- The most widely used one-dimensional barcode in the world. Supports all 128 ASCII characters; ideal for shipping labels, packaging, warehouse management, and package tracking.
- CODE 39 -- Supports uppercase letters (A-Z), digits (0-9), and a set of special characters. Adopted in healthcare, military, industry, and the US government sectors.
- EAN-13 / EAN-8 -- European and international standard for encoding commercial products according to the GS1 system. EAN-13 consists of 12 digits plus an automatically calculated check digit; EAN-8 is designed for small-sized products with 7 digits.
- UPC-A -- North American product encoding standard. Composed of 11 digits and an automatically calculated check digit; mandatory for all products sold in the United States and Canada.
- ITF-14 -- Designed for the identification of containers, cartons, and boxes in supply chains and logistics. Composed of 13 or 14 digits and typically printed on outer packaging.
- MSI (Modified Plessey) -- Primarily used for inventory management, store shelf encoding, and goods tracking in warehouses.
- Pharmacode -- An industrial pharmaceutical standard used in medication packaging lines. Accepts numbers from 3 to 131,070 and is read by specialized scanners.
- Codabar -- Used in public libraries, blood banks, and delivery services. Distinguished by start and stop characters (A, B, C, D) that identify the application type.
Advanced Customization Options
The tool offers a rich set of customization options to match your visual identity and printing requirements:
Colors
Choose the bar color and background color using the interactive color picker. You can match your brand colors or use classic black and white for maximum scanner compatibility.
Dimensions and Measurements
Control the bar width (from 1 to 4 pixels) and barcode height (from 40 to 200 pixels) via smooth sliders. For QR codes, you can adjust the margin from 0 to 10 units.
Text and Font
Enable or disable the display of the text value below the barcode, and adjust the font size from 8 to 24 pixels according to your needs.
Export Formats
After creating the barcode, you can download it in two formats:
- PNG -- A high-resolution (2x) raster image suitable for digital use, home printing, and online sharing.
- SVG -- A vector file that scales infinitely without quality loss; ideal for professional printing and graphic design.
You can also copy the image directly to the clipboard to paste it into any design application or document.
Batch Printing
The batch printing feature allows you to create dozens or hundreds of barcodes in a single operation. Add values manually row by row, or paste a complete list of values at once. Set the desired quantity for each value (up to 500 copies), then print everything in an organized, print-ready window.
Privacy and Security
All barcode creation operations are performed locally in your browser using JavaScript. No data is sent to external servers and the values you enter are never stored. No cookies or tracking mechanisms are used. Your data is completely secure and never leaves your device.
How Do Barcodes Work?
A barcode is a visual representation of data using patterns of bars and spaces (one-dimensional) or matrices of dots and squares (two-dimensional like QR). The optical scanner reads these patterns and converts them into characters and numbers that a computer can understand. Each barcode type uses a different encoding algorithm: CODE 128 uses three character sets (A, B, C) to cover all ASCII characters; EAN-13 employs strict numeric encoding with a check digit calculated by the Modulo 10 algorithm. QR Code uses Reed-Solomon error correction which allows the code to be read even when part of it is damaged.
One-dimensional barcodes (CODE 128, EAN-13, UPC-A, CODE 39) store data only in the horizontal direction and can carry a limited number of characters or digits. Two-dimensional barcodes (QR Code) store data both horizontally and vertically, have a capacity of thousands of characters, and can contain rich content such as URLs, texts, and contact information. One-dimensional barcodes are typically used for product identification and inventory management, while QR codes are preferred for marketing, digital menus, and rapid information sharing.
Practical Use Cases
You can use the barcode generator in numerous practical scenarios: printing product labels for your store, creating inventory barcodes for the warehouse, generating QR codes for business cards or restaurant menus, creating shipping barcodes for packages, preparing shelf labels for stores, and producing pharmaceutical barcodes for packaging lines.
In e-commerce, you need EAN-13 or UPC-A barcodes to list your products on global marketplaces such as Amazon and eBay. In warehouse management, CODE 128 barcodes are used to track goods movements, record incoming and outgoing shipments, and automate inventory counts. In restaurants and cafes, QR codes are used to display digital menus and enable contactless ordering. In healthcare, Pharmacode is indispensable for product verification on medication packaging lines. In libraries, Codabar is the standard solution for tracking books and materials.
Frequently Asked Questions
What is the difference between one-dimensional and two-dimensional barcodes?
One-dimensional barcodes (such as CODE 128, EAN-13) store data only in horizontal bar and space patterns and carry a limited number of characters. Two-dimensional barcodes (such as QR Code) store data both horizontally and vertically and offer a capacity of thousands of characters, including URLs and long texts.
Can I use the generated barcodes commercially?
Yes, the barcodes created with this tool comply with international standards and can be used commercially. However, to sell your products in major retail chains, you will need to obtain an official GS1 prefix for EAN/UPC codes.
Which format is best for professional printing?
The SVG format is best for professional printing because it is vector-based and can be scaled infinitely without any quality loss. The PNG format is suitable for digital use and home printing.
Is there a limit to the number of barcodes I can create?
No, there is no limit whatsoever. You can create as many barcodes as you want for free. The batch printing feature allows you to generate hundreds of barcodes at once.
