How do I make a QR code for free?

Open a browser-based QR generator, paste your URL or text, and download. No signup required. The entire process takes under 10 seconds. For WiFi QR codes, enter your network name and password instead.

Can I change QR code colors to match my brand?

Yes. Change the foreground (dot) color and background color using color pickers. Keep high contrast — dark foreground, light background. Test on multiple phones before printing. Navy on white, dark green on white, and black on brand-colored backgrounds all work well.

How do I create a QR code for WiFi?

Select WiFi as the QR type, enter your network name (SSID), password, and security type (WPA2 is most common). The generator encodes the credentials so any phone scanning the code automatically connects to your network.

Can I put a QR code on a business card?

Yes. Generate a QR code linking to your website, portfolio, LinkedIn, or vCard. Download as SVG for crisp printing at any size. Minimum recommended size for business cards: 2cm x 2cm (about the size of a US quarter).

How do I test if my QR code works?

Scan it with your phone camera before sharing. Test on at least 2 different phones if using custom colors. Scan from the expected distance. For print, make a single test print first — screen and paper scanning can differ slightly.

What is error correction and which level should I use?

Error correction allows a QR code to remain scannable even if partially damaged. Level L: 7% recovery. Level M: 15% (recommended default). Level Q: 25%. Level H: 30%. Higher levels make denser codes but survive more damage. Use M for general purposes, H for outdoor signage that may get scratched.

How to Create a Custom QR Code Free — Colors, WiFi, URL, Every Format

A custom QR code means your brand colors, your content, your format. Here's exactly how to create one for free — no design skills needed, no accounts to create.

Step 1: Choose What to Encode

Content Type	What to Enter	Result When Scanned
Website URL	https://yoursite.com	Opens the website
WiFi Network	SSID + password + security type	Auto-connects to WiFi
Email Address	[email protected]	Opens email composer
Phone Number	+1-555-123-4567	Opens phone dialer
Plain Text	Any text message	Displays the text on screen

Step 2: Customize Colors

The default black-on-white QR code works perfectly, but custom colors make it yours.

Foreground (dots): Use your brand's darkest color — navy, dark green, maroon, black
Background: White or your brand's lightest color
Contrast rule: The foreground must be significantly darker than the background. If you squint and can barely tell them apart, scanners will struggle too.

Color Combinations That Work

Foreground	Background	Reliability	Brand Match
Black (#000000)	White (#FFFFFF)	✓ 100% reliable	Universal / any brand
Navy (#1B2A4A)	White (#FFFFFF)	✓ 99% reliable	Corporate, finance, tech
Dark Green (#1A5632)	White (#FFFFFF)	✓ 99% reliable	Health, eco, food
Dark Red (#8B1A1A)	White (#FFFFFF)	✓ 98% reliable	Food, entertainment
Charcoal (#333333)	Light Gray (#F5F5F5)	✓ 97% reliable	Minimal / modern
White (#FFFFFF)	Black (#000000)	✗ Avoid — inverted	~30% of scanners fail

Step 3: Set Error Correction

Error correction lets QR codes survive partial damage or obstruction.

Level	Recovery	Code Density	Best For
L (Low)	7% of data	Least dense, cleanest look	Digital display, screens
M (Medium)	15% of data	Moderate — recommended default	Business cards, flyers, general use
Q (Quartile)	25% of data	Denser	Outdoor signage, packaging
H (High)	30% of data	Most dense	Heavy-wear environments, stickers

Step 4: Download as PNG or SVG

PNG — for digital: email signatures, social media posts, websites, messaging. Fixed resolution, universally compatible.
SVG — for print: business cards, posters, flyers, packaging. Infinitely scalable — prints crisp at any size from 2cm to 2 meters.

Product packaging: QR linking to setup instructions, warranty registration, or support page. Use error correction level Q or H for durability.
