Free Online QR Code Generator 2026

Welcome to Code Formatter QR Generator – the simplest and most customizable way to create Quick Response (QR) codes instantly. A QR code is a 2D matrix barcode that can store URLs, text, Wi-Fi credentials, or contact info. Smartphones can scan these codes in milliseconds, bridging the gap between the physical and digital worlds.

Unlike other generators that require sign-ups or put expiration dates on your codes, our tool creates static, permanent QR codes that never expire. They are generated locally in your browser, ensuring maximum privacy and speed.

How to Create a QR Code

Generate your custom code in 3 steps:

1. Enter Content

Type your website URL, plain text, or email address in the input box. The QR code updates in real-time as you type.

2. Customize Appearance

Adjust the Size (up to ultra-high resolution) and pick custom Foreground and Background colors to match your brand identity.

3. Download

Click the Download icon to save your QR code as a distinct, high-quality PNG image ready for print or web use.

Technical Configuration

Error Correction Levels

QR codes have built-in redundancy, allowing them to be scanned even if damaged. Our tool lets you choose the level:

Low (L - 7%): Best for small codes with lots of data. The code pattern is less dense.
Medium (M - 15%): The standard default. Good balance of density and reliability.
Quartile (Q - 25%): Better reliability. Recommended if you plan to add a logo overlay later in Photoshop.
High (H - 30%): Highest redundancy. The code is larger and more complex, but can survive significant damage or dirt.

Use Cases

1. Website & Marketing

Direct users to your landing page, social media profile, or app download link. Print them on flyers, business cards, or product packaging.

2. Wi-Fi Access

Encode your Wi-Fi credentials (`WIFI:S:MyNetwork;T:WPA;P:MyPassword;;`) so guests can join your network simply by scanning the code.

3. vCards (Contacts)

Share your contact details instantly. When scanned, the phone prompts to save your name, number, and email to the contacts list.

Frequently Asked Questions

Do these QR codes expire?

No. These are static QR codes. The data is encoded directly into the pattern. As long as your link works, the QR code works forever.

Can I see how many people scanned it?

No. Since these are static codes, we don't track them. To track scans, you would need a dynamic QR code service that redirects through a tracking URL.

Why is my QR code hard to scan?

Ensure there is high contrast between the foreground and background (dark on light is best). Also, avoid making the code too small or using too much text with "Low" error correction.

Can I add a logo in the middle?

Our tool generates the raw QR pattern. You can download the image and use an image editor to place a small logo in the center. Use "High" error correction to ensure it remains scannable.

Is it free for commercial use?

Yes! You can use the generated images for any purpose, including commercial products, without attribution.

Is my data private?

Absolutely. The generation happens 100% in your browser using JavaScript (`qrcode.js`). We never see or store your data.
