About Barcode Generator
CODE128 is a high-density linear barcode format that encodes all 128 ASCII characters and is widely used in logistics, retail, healthcare and manufacturing for labelling packages, inventory items, documents and products. This tool generates CODE128 barcodes directly in your browser and lets you download them as PNG or SVG files with no watermark, no account and no usage limits.
How to use Barcode Generator
Enter the text or number you want to encode in the input box and click Run. The barcode appears as a preview in the output area. Download as PNG for immediate printing or digital use, or as SVG for scalable, print-ready output that maintains sharp edges at any size.
When to use this tool
Use this for generating barcodes for internal inventory labelling, document tracking, product mockups, packaging design proofs, warehouse management, library cataloguing or any application that requires a CODE128 barcode without purchasing dedicated software.
Privacy
Barcode generation usually requires dedicated software or paid online services. This tool generates standard CODE128 barcodes entirely in your browser with no installation, no account and no usage limits. All processing runs locally — nothing is uploaded.
Frequently asked questions
What barcode format does this tool generate?
CODE128, which encodes the full ASCII character set including letters, numbers and common punctuation. CODE128 is one of the most widely supported linear barcode formats and is accepted by virtually all standard barcode scanners.
Can I use the barcodes for commercial purposes?
Yes. The generated CODE128 barcodes are standard format and can be used for any purpose including commercial labelling, retail packaging and product identification.
What size should I download for print?
Download the SVG version for any print use — it scales to any resolution without losing quality. Use PNG for digital displays, documents and presentations where a fixed pixel size is suitable.
Is there a length limit for the encoded value?
CODE128 can encode strings of any practical length. However, very long strings produce very wide barcodes that may be difficult to scan with standard scanners. For most labelling applications, values under 20 characters scan most reliably.
Does the tool add a watermark?
No. The downloaded PNG and SVG files contain only the barcode with no watermark, logo or branding from this tool.
