How to make a barcode

Pick a symbology, type your value, and the barcode renders live with the format validated as you type (EAN-13 wants 12–13 digits, UPC wants 11–12, and so on). Tweak the bar width, height, colours and label, then download as PNG or SVG. Need lots? Switch to Batch, paste one value per line, and download them all as a ZIP.

A barcode generator turns a number or text into a scannable barcode. TechWhack supports the common retail and logistics symbologies (Code 128, EAN-13/8, UPC, Code 39, ITF-14, Codabar, MSI), validates your input live, and can generate a whole list at once as a ZIP — all in your browser, no watermark, nothing uploaded.

Which barcode type

Use Code 128 for general text and SKUs (it is compact and encodes anything), EAN-13/EAN-8 and UPC for retail products, Code 39 for asset tags and ID cards, ITF-14 for shipping cartons, and Codabar for libraries and labs. If you are not sure, Code 128 is the safe all-rounder.

FAQ

What is the difference between EAN-13, UPC, and Code 128?EAN-13 (13 digits) and UPC (12 digits, mainly North America) are retail product codes scanned at checkout and require a registered number, while Code 128 is a flexible alphanumeric code used for shipping labels and internal tracking with no registration. Use retail codes to sell products and Code 128 for logistics or inventory.

Can I use a self-generated retail barcode to sell on Amazon or in stores?For retail you need a number registered through GS1 so it is globally unique; a self-generated EAN or UPC can collide with another company product. These codes are great for internal use, prototyping, and inventory, but register the number before public retail distribution.

Which barcode types can it generate?It supports Code 128, EAN-13, EAN-8, UPC, Code 39, ITF-14, Codabar, and MSI, covering retail, shipping, and inventory needs. Live input validation warns you if the data does not fit the chosen symbology.

Can I create many barcodes at once from a list?Yes. Enter a list of values and they are batch-generated and bundled into a ZIP, which saves time over making them one by one. There is no watermark on any of the output.

Why is my barcode rejected as invalid?Each symbology has rules, such as EAN-13 needing exactly the right number of digits and numeric-only data, so a wrong length or a letter in a numeric code is flagged. The live validation tells you what the chosen format expects so you can fix the input.
