What is the difference between the PNG and SVG download?

PNG is a fixed-resolution image exported at 3x for crisp printing. SVG is a vector file that scales to any size without losing sharpness, ideal for print layouts and packaging.

About this barcode generator

This tool turns any value into a scannable 1D barcode without an account, a server round-trip, or ad tracking. Pick a format, type your content, tune the bar size, and export a print-ready PNG or a vector SVG. It supports CODE128 for general text and numbers, plus the retail standards EAN-13 and UPC-A, with check digits handled for you.

Quick answer: To create a barcode, choose a format (CODE128, EAN-13 or UPC-A), type or paste your value, adjust the bar width and height, then select Download PNG or Download SVG. Everything runs in your browser, so no upload or sign-up is needed.

What is a barcode?

A barcode is a machine-readable pattern of parallel bars and spaces that encodes data such as a product number or SKU. A scanner reads the relative widths of the bars to recover the original value. This generator produces three widely used 1D (linear) symbologies: CODE128, EAN-13 and UPC-A.

How to create a barcode

Select a format standard: CODE128, EAN-13 or UPC-A.
Enter your content — text or numbers for CODE128, or digits for EAN-13 and UPC-A.
Adjust the bar width and height, and toggle the human-readable text on or off.
Download the result as a PNG image or a scalable SVG vector.

Frequently asked questions

Is my data uploaded anywhere?

No. Every barcode is encoded and rendered inside your browser. Nothing you type leaves the page and no sign-up is required.

Which barcode formats are supported?

CODE128 for any printable text or numbers, EAN-13 for 12 or 13 digit retail codes, and UPC-A for 11 or 12 digit codes used across North American retail.

Do I need to add the check digit myself?

No. Enter 12 digits for EAN-13 or 11 digits for UPC-A and the correct check digit is calculated and appended automatically. Paste a full-length code and its check digit is verified for you.

PNG or SVG — which should I download?

PNG is a fixed-resolution image exported at 3x for crisp printing. SVG is a vector that scales to any size without losing sharpness, ideal for packaging and print layouts.

Is this barcode generator free?

Yes. It is completely free with no sign-up, no watermark, and no usage limit. Because everything runs in your browser, there is nothing to install.

Can I sell products with a barcode made here?

This tool renders any EAN-13 or UPC-A number you provide. For products sold through major retailers, the number itself must be a genuine GS1-issued code — the generator draws the barcode but does not assign official GS1 numbers.
