100% private: barcodes are generated entirely in your browser — nothing is uploaded to any server. Strict formats like EAN-13 and UPC require an exact number of digits; if the data is invalid the last valid barcode stays on screen and an error explains what is needed.
Generate barcodes in Code128, EAN, UPC and other formats, then download them as a PNG or SVG. Enter your data, choose a format and styling, and the barcode renders live in your browser with no watermarks.
Frequently asked questions
How do I create a barcode?
Type or paste your data, pick a barcode format such as Code128 or EAN-13, adjust the size and colours if needed, and download the result as a PNG or scalable SVG.
Which barcode format should I use?
Code128 is a good general-purpose choice for text and numbers. EAN-13 and UPC are used for retail products and require a specific number of digits. The tool will warn you if your data does not fit the chosen format.
