Barcode Generator
Make a real, scannable barcode in the browser: pick the symbology, type the value, watch it draw live, and download a print-sharp PNG or a resolution-free SVG.
The barcode is drawn right here in your browser — the value you type is never uploaded. A short ad is shown before the download — it keeps this tool free.
Make a real, scannable barcode in the browser: pick the symbology, type the value, watch it draw live, and download a print-sharp PNG or a resolution-free SVG. Code 128 for general labels, EAN-13 and UPC-A for products, Code 39 for warehouse and ID work, ITF-14 for shipping cartons — with correct check digits computed for you and plain-language errors when a value cannot fit the format you picked.
The Barcode Generator on FreeConverter is the privacy extreme of the toolbox: it runs entirely in your browser, so the file is never uploaded at all — no temporary folder, no server copy, nothing to delete afterwards. Sensitive documents get edited on the device they already live on.
How to use the barcode generator
- Pick the barcode format — Code 128 for general use, EAN-13 or UPC for retail products, ITF-14 for shipping cartons.
- Type the value; the barcode redraws live and tells you plainly if the value does not fit the format (wrong length, missing digits).
- Download the barcode as a print-sharp PNG or a scalable SVG — it was generated entirely in your browser.

- Private by design: this tool runs entirely in your browser — your file never leaves your device, and nothing is uploaded, stored or shared.
- Fast: this page is a fraction of the size of the ad-heavy alternatives, and the same account-free toolbox has 530 other tools when you need them.
FAQ
Which barcode format should I use?
Code 128 is the safe general choice — it encodes any text or number and every modern scanner reads it. EAN-13 and UPC-A are the retail standards (they need a registered product number to be meaningful at a real checkout). Code 39 suits warehouse and ID labels; ITF-14 is the shipping-carton standard.
Will a generated barcode actually scan?
Yes — the bars are drawn by the JsBarcode library to the real symbology rules, check digits included, and the QR Code Scanner tool on this site reads them straight back. For retail shelves you still need an officially assigned product number; the generator cannot assign one.
Is this really free?
Yes — completely. A short ad before the export keeps every tool free; no account, subscription or credits are ever required.
What happens to my file?
Nothing is uploaded at all. This tool runs entirely in your browser — your file never leaves your device, and nothing is stored or shared.
Do I need to install anything?
No. The tool is built into this page — any modern phone, tablet or computer browser works.
