Free Barcode Generator
Create professional barcodes for products, inventory, assets, labels, packaging, and internal tracking. Customize the design, generate batches, and download print-ready files without uploading your data.
Create barcodes without installing software
A barcode converts an identifier into a pattern that compatible scanners can read quickly. This generator creates the barcode directly in your browser and gives you control over the symbology, dimensions, colors, readable text, margins, and export format.
Use single mode for one product or asset. Use batch mode to transform a list of identifiers into a printable sheet or downloadable ZIP archive.
Popular barcode formats
- Code 128: compact, flexible, and suitable for inventory, logistics, shipping, and internal systems.
- EAN-13 and UPC-A: widely used on consumer products at retail points of sale.
- Code 39: common in manufacturing, automotive, government, and industrial labeling.
- ITF-14: designed for cartons, cases, and higher-level product packaging.
- Codabar and MSI: used in selected libraries, laboratories, inventory, and legacy systems.
How to create a reliable barcode
Select the correct format. Match the symbology to your scanner, software, and intended use.
Enter a valid value. Numeric-only formats have exact length and character requirements.
Preserve the quiet zone. White space around the bars helps scanners identify the barcode boundaries.
Use strong contrast. Dark bars on a plain light background are the most reliable combination.
Test before deployment. Scan the final printed label using the actual devices and software used in your workflow.
Barcode design and printing tips
Do not stretch a raster barcode after downloading it because uneven resizing can alter bar proportions. Download SVG when the barcode must be scaled for packaging, posters, or professional print layouts.
Avoid decorative gradients, shadows, textured backgrounds, and low-contrast color combinations. Unlike a graphic logo, a barcode must preserve precise relationships between bars and spaces.
For small labels, test multiple bar widths and heights. The smallest attractive barcode is not always the most reliable barcode.
Frequently asked questions
Yes. You can generate, customize, preview, print, and download barcodes without creating an account.
No. Barcode rendering takes place in your browser. The values you enter are not submitted to the website or stored in a database.
The generator supports Code 128, Code 128A, Code 128B, Code 128C, EAN-13, EAN-8, UPC-A, Code 39, ITF-14, ITF, Codabar, MSI variants, and Pharmacode.
Code 128 is a strong general-purpose choice for inventory and logistics. EAN-13 and UPC-A are common for retail products. Code 39 is widely used in industrial labeling, while ITF-14 is commonly used for cartons and packaging.
Yes. For EAN-13, EAN-8, UPC-A, and ITF-14, you may enter the data without the final check digit and the tool will calculate it automatically.
Yes. Batch mode accepts one value per line and produces a printable sheet. You can also download all generated barcodes as a ZIP archive.
Single barcodes can be downloaded as SVG, PNG, JPEG, or WebP. Batch barcodes can be downloaded together in a ZIP file.
No. A barcode is a visual representation of its encoded value. It remains usable as long as the printed or digital image remains readable and the associated value remains meaningful in your system.
The image can represent a valid EAN or UPC number, but this tool does not issue globally unique retail identifiers. Official retail numbers should be obtained from the appropriate GS1 organization or another authorized source.
Common causes include an invalid value, insufficient contrast, excessive resizing, missing quiet zones, low print quality, or using a symbology unsupported by the scanner. Test the final barcode at its intended size.
SVG is usually best for professional printing because it remains sharp at any size. PNG is convenient for documents and websites when used at a sufficiently high resolution.
No. Traditional barcodes are one-dimensional and usually encode shorter identifiers. QR codes are two-dimensional and can hold considerably more information, including URLs, contact details, and Wi-Fi credentials.
