Everything you need to know about Barcode Generator
How barcode formats work, which one to pick, and how to get a scannable result.
- Type a value, pick a format, and your barcode renders instantly.
- Everything runs locally in your browser — nothing you type is ever uploaded.
- Not every value works with every format — check the format guide below before you print.
How to use Barcode Generator
- Type the text or number you want encoded into the input field.
- Choose the barcode format that matches your value — CODE128, EAN-13, UPC-A, CODE39, or another supported type.
- Your barcode renders instantly — download it as a PNG or SVG file.
Why generate a barcode online
Design software and dedicated labeling programs can create barcodes, but they usually require an install, a license, or an account just to produce a single scannable image.
This tool skips all of that: it renders the barcode live in your browser using JavaScript, so you get a print-ready PNG or SVG in seconds, with nothing to install and nothing sent to a server.
Choosing a barcode format
| Format | Best for | Why it's worth checking |
|---|---|---|
| CODE128 Recommended | General purpose, shipping, internal tracking | Accepts letters, numbers and symbols, so it fits almost any value. |
| EAN-13 / UPC-A | Retail products | Required by most point-of-sale systems, but needs a valid product number. |
| CODE39 | Inventory, ID badges, older scanners | Widely supported by legacy hardware, but only encodes uppercase letters and numbers. |
Barcode Generator without uploading anything
The value you type is passed directly to a barcode-rendering script running in your own browser tab — it's drawn to an on-page image and never transmitted anywhere.
Because nothing is uploaded, there's no server-side size limit either; the only practical constraint is how much text a given barcode format can encode.
Your data never leaves your device. Barcode rendering happens entirely client-side, with nothing logged or stored.
Need to turn that barcode into a label sheet? The Image to PDF tool can combine it with other images into a printable PDF.
What value does each format expect?
| Format | Valid input | Trade-off |
|---|---|---|
| CODE128 Good default | Any letters, numbers, and most symbols | Most flexible, but not the standard for retail scanning at checkout. |
| EAN-13 | 12–13 digits | Standard for retail products worldwide, but won't accept letters. |
| UPC-A | 11–12 digits | Common in the US/Canada retail, but limited to numbers only. |
| CODE39 | Uppercase A–Z, 0–9, and a few symbols | Reliable on older scanners, but takes up more horizontal space per character. |
If you're not sure which to pick, CODE128 accepts almost anything and is a safe starting point — switch to EAN-13 or UPC-A only if a specific retail system requires it.
