Create a QR code online for a website URL, plain text, email address, phone number, Wi-Fi network, or contact details. Deep Vision Agency’s free QR Code Generator lets you enter your information, customize the code, preview the result, and download it as PNG or SVG. The current tool also provides controls for size, colors, and error correction.

No QR-code software is required. Enter your information above and generate your code.

What Is a QR Code?

A QR code (Quick Response code) is a two-dimensional barcode that stores information in a pattern of square modules. A compatible smartphone camera or QR scanner can read the pattern and interpret the encoded information.

Depending on the data stored in the code, scanning it can open a website, display text, prepare an email, initiate a phone action, connect to a Wi-Fi network, or provide contact information.

QR Code is an established standardized technology, with the current international specification covered by ISO/IEC 18004:2024.

What Can You Create With This QR Code Generator?

The Deep Vision Agency QR Code Generator currently supports several practical data types.

URL QR Code

Create a QR code that contains a website address.

For example, you can use one on:

• Business cards

• Posters

• Flyers

• Product packaging

• Menus

• Event materials

• Printed advertisements

A user can scan the code instead of manually typing the web address.

Text QR Code

Encode plain text into a QR code.

This can be useful for short instructions, notes, messages, or information that you want people to access by scanning.

Email QR Code

Create a code containing an email address, with optional subject and body information supported by the tool.

This can make it easier for customers, visitors, or contacts to start an email interaction.

Phone QR Code

Create a QR code containing a phone number.

This can be useful on business cards, posters, brochures, storefront materials, and other offline marketing assets.

Wi-Fi QR Code

Enter your Wi-Fi network name, password, and security type to create a QR code for sharing network access.

This can be convenient for:

• Restaurants

• Hotels

• Offices

• Shops

• Events

• Homes

• Guest areas

Because a Wi-Fi QR code can encode network credentials, only share it with people who are supposed to have access to that network.

vCard QR Code

Create a QR code containing contact information such as:

• First name

• Last name

• Phone number

• Email address

• Organization

• Website

This can be useful for digital business cards and printed contact materials.

How to Create a QR Code Online

Creating a QR code with the tool is straightforward.

1. Choose the QR Code Type

Select the type of information you want to encode:

• URL

• Text

• Email

• Phone

• Wi-Fi

• vCard

Choose the option that matches your intended use.

2. Enter Your Information

Fill in the relevant fields.

For example, if you are creating a website QR code, enter the URL you want people to open after scanning.

For a contact QR code, enter the contact details you want to share.

3. Customize the QR Code

The generator provides controls for:

• Size

• Foreground color

• Background color

• Error correction level

Choose settings that keep the code easy to scan.

4. Check the Preview

Review the generated QR code before downloading it.

For important printed materials, scan the final code with a phone to confirm that it works as expected.

5. Download the QR Code

The tool provides PNG and SVG download options.

PNG is convenient for many digital applications, while SVG is useful when you need a scalable vector file for print or design work.

QR Code Error Correction Explained

QR codes include error-correction mechanisms that can help recover encoded information when part of the symbol becomes damaged or difficult to read.

The standard provides four error-correction levels:

Higher error correction can improve resilience, but it also increases the amount of data used for recovery and can result in a denser QR code. DENSO WAVE notes that Level M is commonly selected, while higher levels can be useful in environments where codes may become dirty or damaged.

The right setting depends on where and how the QR code will be used.

Why QR Code Size Matters

A QR code is made from small square elements called modules. Its required physical size depends on factors including the QR version, amount of encoded information, module size, printing quality, and scanner capability.

If you are placing a QR code on a large poster, for example, you have more space to make it comfortably scannable. A very small code on a printed card may require more careful testing.

For printed materials, test the actual final-size version rather than assuming that a code that scans on your computer screen will automatically scan when printed.

Keep the QR Code’s Quiet Zone Clear

The empty area surrounding a QR code is called the quiet zone.

DENSO WAVE’s QR Code guidance specifies a clear margin of at least four modules around all sides of a standard QR Code. This space helps scanners distinguish the code from surrounding visual elements.

When placing a QR code on a poster, business card, menu, packaging, or advertisement, avoid putting text, borders, graphics, or other elements too close to the code.

PNG vs SVG: Which QR Code Format Should You Use?

The generator lets you download the QR code as PNG or SVG.

SVG is a vector format, so it can be resized without the same pixelation concerns associated with raster images.

For professional printing, the final artwork should still be tested at its intended physical size.

Where Can You Use QR Codes?

QR codes connect physical materials with digital information. Some common applications include:

Business Cards

A QR code can provide a convenient way to share contact details or direct someone to a website.

Restaurants

Restaurants can use QR codes to link customers to digital menus, websites, ordering pages, or other online resources.

Retail and Ecommerce

A QR code on packaging or printed promotional material can direct customers to a product page, support information, or a website.

Events

Event organizers can use QR codes to share registration pages, schedules, venue information, tickets, or other event resources.

Marketing Materials

QR codes can connect offline campaigns with online destinations such as landing pages, product pages, contact forms, or websites.

Wi-Fi Access

Businesses, hotels, offices, classrooms, and homes can use Wi-Fi QR codes to make network access easier for visitors.

Education

Teachers and students can use QR codes to connect printed materials with online resources, assignments, reference pages, or learning materials.

QR Codes for SEO and Digital Marketing

A QR code itself does not replace SEO.

Its main purpose is to make digital information easier to access from physical or offline environments.

For marketers, a QR code can connect:

Printed material → QR scan → Website or landing page

For example, a business could place a QR code on a flyer that opens a dedicated campaign landing page.

If you use QR codes in marketing campaigns, make sure the destination page is relevant to the material where the code appears. A QR code that opens a confusing or unrelated page creates unnecessary friction for the user.

For campaign measurement, marketers can also use appropriately configured tracking URLs where their analytics setup supports them. The QR code simply encodes the URL; analytics depend on the destination and tracking setup.

Static QR Codes vs Dynamic QR Codes

A key distinction is how the QR code handles its destination.

Static QR Code

A static QR code stores the information directly in the code.

If it contains a website URL, that URL is encoded into the QR pattern. Changing the destination generally requires creating and distributing a new code.

Dynamic QR Code

A dynamic QR code commonly uses a redirect or management service so the destination can be changed later and additional tracking features may be available.

The Deep Vision Agency generator is designed around the QR data entered into the tool and currently provides generation for URLs, text, email, phone, Wi-Fi, and vCard information. The page describes the generated codes as static.

For a printed campaign where the destination may need to change later, understand this distinction before distributing the code.

Best Practices for Creating a Scannable QR Code

A QR code only helps if people can scan it reliably.

Use Strong Contrast

Keep sufficient visual contrast between the QR code and its background.

Avoid combinations where the code blends into the surrounding design.

Leave Enough Empty Space

Keep the required quiet zone around the code clear. DENSO WAVE specifies a four-module margin around a standard QR Code.

Avoid Making It Unnecessarily Small

A smaller QR code is not automatically better.

The required size depends on the printing environment, module size, scanner capability, viewing distance, and amount of encoded information.

Don’t Encode More Information Than Necessary

Adding unnecessary data can make a QR code denser.

If your goal is simply to send someone to a webpage, a concise URL is usually more practical than encoding a large amount of unnecessary text.

Test Before Publishing

Always scan the finished QR code with a phone before printing or distributing it.

For printed campaigns, test the actual printed version at the intended size.

Check the Destination

A technically scannable QR code can still create a poor experience if the destination page is slow, broken, difficult to use on mobile, or no longer relevant.

The QR code and the destination should be treated as one user journey.

Common QR Code Mistakes

1. Poor Contrast

A QR code that blends into its background can become difficult for cameras to recognize.

2. Removing the Quiet Zone

Surrounding the code with graphics or text can interfere with reliable recognition.

3. Printing It Too Small

A code that works on a large computer display may not work equally well when reduced for a small printed surface.

4. Skipping the Final Scan Test

Always test the actual version users will encounter.

5. Sharing Sensitive Information Carelessly

A QR code is not automatically a secure container for private information.

Anyone who can scan a code may be able to read or act on the information encoded in it. For example, a Wi-Fi QR code containing a network password should be shared appropriately.

6. Forgetting the Destination

If a QR code points to a webpage, the webpage still needs to remain available.

A static QR code containing a URL does not make a deleted or moved webpage work again.

When Should You Use a QR Code?

Use a QR code when it provides a clear advantage over manually typing or remembering information.

Good examples include:

• Opening a long website URL

• Sharing contact information

• Connecting to Wi-Fi

• Opening a digital menu

• Accessing event information

• Connecting printed marketing to a landing page

• Sharing a website from a physical advertisement

A QR code is less useful when the information is already easier to access directly or when the user has no practical reason to scan it.

What does QR code error correction mean?

Error correction allows a QR code to recover some encoded information even when part of the symbol is damaged or obscured. QR Code provides four levels: L, M, Q, and H, with approximate recovery capabilities of 7%, 15%, 25%, and 30%, respectively.

Do QR codes expire?

A static QR code itself does not have an expiration date. However, what happens after scanning depends on the information encoded in it. For example, if a QR code contains a URL and that webpage is removed, the QR code cannot make the deleted page available again.

How can I make sure my QR code scans correctly?

Use good contrast, keep the surrounding quiet zone clear, avoid making the code unnecessarily small, and test the final QR code with a smartphone before publishing or printing it. DENSO WAVE recommends a four-module clear margin around a standard QR Code.
