Generate Code 128, EAN-13, UPC-A, Code 39, and standard retail barcodes in sharp vector SVG or PNG formats.
The Barcode Generator helps you create standardized barcodes for inventory management, retail products, shipping labels, and packaging. You can select your desired barcode format, enter an alphanumeric or numeric code, and download your barcode immediately.
All barcode rendering is calculated locally inside your browser. No tracking or server requests take place, and you can export crisp vector SVG files or high-resolution PNG images suitable for professional label printing.
Store owners generate UPC-A and EAN-13 barcodes for physical product packaging and point-of-sale scanning.
Logistics coordinators create Code 128 barcodes for tracking carton numbers and shipping pallets.
IT managers generate Code 39 tags for office laptops, monitors, and equipment tracking.
Select your standard, such as Code 128, EAN-13, UPC-A, or Code 39.
Type the product number or text string you want to encode.
Adjust bar height, width, and colors, then download in SVG or PNG format.

EAN-13 automatically validates the final check digit to ensure scanner readability.
Solution: Check your digit count. UPC-A requires 11 or 12 digits, while EAN-13 requires 12 or 13 digits. Use Code 128 if you have letters or variable lengths.
Solution: Ensure your printer prints with high contrast (dark black on white paper) and leave empty margins (quiet zones) on both sides of the barcode.
MWT Labs tools are built using modern web primitives—including WebAssembly, Web Workers, and native HTML5 Canvas / Cryptography APIs. When you process images, parse PDF documents, format JSON payloads, or calculate financial schedules, execution happens strictly within your local browser memory sandbox.
You can generate Code 128 (ideal for alphanumeric tracking and shipping), EAN-13 and EAN-8 (for retail products worldwide), UPC-A and UPC-E (standard North American retail), Code 39, and ITF-14.
Vector SVG is best for printing because it scales infinitely without pixelation or blurriness at any print size. High-resolution PNG is also available for websites and digital documents.
Yes. All barcodes generated on MWT Labs are 100% free for both personal and commercial use. Note that retail stores generally require registered GS1 barcode numbers.
Yes. You can adjust the bar thickness, overall height, display or hide the human-readable text below the bars, and change colors to match your brand styling.
Scanners require high contrast between dark bars and a light background. Printing with dark black ink on a plain white surface with plenty of quiet space (blank margin) around the code ensures instant scanning.
