Is the barcode generator free?

Yes. QRsnapp's barcode generator is 100% free with no sign-up, no watermark and no limits. All formats and design options are free forever.

Which barcode formats does it support?

We support 10+ barcode formats: Code 128, Code 39, Code 93, EAN-13, EAN-8, UPC-A, UPC-E, ITF-14, ITF, MSI, Codabar and Pharmacode.

What format should I choose for retail products?

For retail products sold in stores, use EAN-13 (worldwide) or UPC-A (US/Canada). For shipping containers, use ITF-14. For internal use, Code 128 is the most flexible — it supports letters, numbers and symbols.

Can I customize the colors?

Yes. You can change the bar color, background color, text color and apply one of 12 pre-built design templates. Keep enough contrast between bars and background so scanners can read the code.

What formats can I download?

You can download your barcode as PNG (transparent or solid), SVG (vector, scales to any size) or JPG. SVG is recommended for print.

Are these real, scannable barcodes?

Yes. The generator produces standard, fully scannable barcodes using the official specifications for each format. You can scan them with any barcode scanner or smartphone app.

Do you store the barcode data?

No. Everything runs in your browser. Your barcode data is never uploaded to any server.

Common questions

Everything you need to know about generating barcodes.

Is this barcode generator really free?

Yes. 100% free, no sign-up, no watermark, no expiry. Every format and every design option is free forever. Use the barcodes you create for any purpose, including commercial.

Which format should I use?

For retail products, use EAN-13 (worldwide) or UPC-A (US/Canada). For shipping cases, use ITF-14. For internal use (warehouses, SKUs, asset tags), Code 128 is the most flexible — it accepts letters, numbers and symbols and is very compact.

Are the barcodes scannable by real scanners?

Yes. All barcodes follow the official specification for each standard and have been tested with industry-standard scanners and smartphone apps. The check digits are calculated automatically where required.

What's the difference between a barcode and a QR code?

A barcode is one-dimensional — vertical lines that store about 20–25 characters, mostly used for retail products and inventory. A QR code is two-dimensional and can store thousands of characters: URLs, contact cards, WiFi credentials, etc. Read our full comparison →

Can I print barcodes from this site?

Yes. For print, always download the SVG version — it's a vector format that scales to any size without losing quality. PNG and JPG are fine for digital use. Stick to high-contrast colors (dark bars on a light background) and don't shrink barcodes below the minimum recommended size for the format.

Why does the validity indicator turn red?

Some barcode formats only accept specific characters or lengths. For example, EAN-13 needs exactly 12 digits, UPC-A needs 11, Pharmacode needs a number between 3 and 131070. The indicator tells you when your input doesn't match the chosen format so you can adjust.

How do I get an official EAN / UPC code?

If you're selling products commercially in stores, you need to register your codes with GS1 to get an official, globally unique number. This generator will produce a perfectly scannable barcode from any valid digit string, but for genuine retail use you need a registered GS1 number to avoid conflicts.

Is my data private?

Yes. Everything runs in your browser. Your barcode content is never uploaded to any server, never saved, never shared.

About barcodes

A 30-second history of the lines we scan every day.

What is a barcode?

A barcode is a machine-readable visual pattern that encodes data using varying widths of parallel lines. They were invented in 1949 by Norman Joseph Woodland and Bernard Silver, and first used commercially in a Marsh supermarket in 1974 to scan a 10-pack of Wrigley's gum. Today barcodes are everywhere — retail, logistics, healthcare, libraries, manufacturing.

Linear vs 2D codes

Traditional barcodes are linear (1D): a single row of bars storing about 20–25 characters. They're cheap, fast and universally supported. 2D codes like QR codes use a grid pattern to store thousands of characters and even error-correction data. If you need to encode a URL, contact card or WiFi network, use our QR code generator instead.

How to print barcodes correctly

Always download SVG for print — vector graphics scale without blur. Keep enough contrast between the bars and background (dark bars on light backgrounds work best). Don't apply effects, gradients or rotations to the bars. Leave a quiet zone (white margin) around the barcode equal to at least 10× the bar width. And test-scan your printed barcode before going to production.

Free for commercial use

The barcodes you generate here are royalty-free and yours to use however you want — product packaging, shipping labels, business cards, internal asset tracking. The one exception: if you're selling products through major retailers, you need a registered GS1 number to ensure your EAN/UPC code is globally unique. Get in touch if you have questions.
