Online Barcode Generator: Create and Download Barcodes
Create a barcode online from a number or short piece of text, choose a format that fits your use case, and download a ready-to-use PNG or SVG. This guide also explains barcode formats, product numbers and practical scanning tips.
What Is a Barcode Generator and Barcode Maker?
A barcode generator turns a number or short piece of text into a pattern of bars that a barcode scanner can read. An online barcode maker does the same job in your browser, without requiring desktop software.
This tool creates linear, or one-dimensional, barcodes. It checks your input against the rules of the selected format, adds a check digit when the format supports it, and draws the result for download. You can use it as a free barcode maker for testing, internal labels, documents and other permitted uses.
If you are looking for a product barcode generator or a barcode with price, remember that the barcode normally represents an identifier rather than the price itself. Product systems can associate that identifier with a price in their database. This tool creates the barcode graphic from the number or text you provide.

How to Generate a Barcode Online
- Choose a barcode format. The hint below the format menu explains which characters or digit length it accepts.
- Enter your number or short text. The barcode preview updates as you type.
- Adjust the bar width, height, quiet margin, colours and visible text to suit your label or document.
- Download PNG for everyday documents and apps, or SVG when you need a sharp, scalable file for print and design.
Barcode Printing Tips: Make Codes Easier to Scan
- Keep dark bars on a light background. Light bars on dark, or low-contrast colours, often fail to scan.
- Leave the blank margin around the bars and do not crop it.
- Do not stretch the image in one direction. Resize it evenly, or use the SVG.
- Test a printed sample with the scanner you will use before printing a whole batch.
- For retail products, use the product number assigned to your business by the appropriate standards organization. This generator creates the visual barcode but does not issue or register a product number.
Barcode Generator Limitations and Privacy
Privacy
Your text is turned into a barcode in your browser and is not sent anywhere or stored. A small drawing library loads from a public CDN the first time you use the tool, and it does not receive your text.
Limitations
This tool makes linear barcodes only, not QR codes. It does not register retail numbers, and it cannot confirm that a printed code works with your scanner, so always test one.
