What is a QR code and how does it work?

A QR code is a two-dimensional barcode that stores information in the form of small black and white squares. The name "QR" stands for Quick Response, as the embedded data can be recognized by smartphones, tablets, or special scanners within seconds.

Unlike traditional barcodes, a QR code can store significantly more information. Depending on the application, you can store, for example, websites, contact details, Wi-Fi access, phone numbers, email addresses, or simple text. After scanning, the smartphone automatically performs the desired action, without the need for manual input.

Today, almost all current smartphones support QR codes directly via their integrated camera. In most cases, additional apps are no longer necessary.

Another advantage is that QR codes can be used both digitally and in print. For example, they work on:

  • Business cards
  • Flyers
  • Brochures
  • Posters
  • Packaging
  • Product labels
  • Invoices
  • Websites
  • Shop windows
  • Exhibition stands

This makes them suitable for businesses as well as individuals, clubs, or freelancers.

How to create your QR code in a few steps

Louvion's QR Code Generator was designed to be simple. You don't need any prior knowledge or registration. After just a few entries, your finished QR code will be ready for download.

1. Select the appropriate QR code type

First, choose what information your QR code should contain. Depending on your selection, the appropriate input fields will be displayed automatically.

The generator currently supports the following QR code types:

QR Code Type
Usage
  • Website
  • Contact
  • WhatsApp
  • Social Media
  • Email
  • Phone
  • WiFi
  • Text
  • Opens a website
  • Saves contact details directly to the smartphone
  • Starts a WhatsApp chat
  • Links to social media profiles
  • Opens a new email
  • Starts a call
  • Connects devices to a Wi-Fi network
  • Displays any text

This allows you to tailor the QR code precisely to your intended use.

2. Enter Content

After selecting the desired type, you enter the required information.

Depending on the QR code, this could be, for example:

  • Website address
  • Phone number
  • Name and contact details
  • Wi-Fi name and password
  • Social media profile
  • Email address
  • Free text

Many inputs are automatically simplified. For example, you no longer need to enter "https://" for websites. The generator automatically adds missing components if a valid address is recognized.

3. Customize Your QR Code

You can then adjust the appearance to match your brand or design.

The following options are available, among others:

  • Custom QR code color
  • Individual background color
  • HEX color codes
  • Various QR code styles
  • Your own logo
  • Real-time preview

All changes are displayed immediately. This way, you can see how your finished QR code will look during the design process.

Once everything is perfect, you can directly download the QR code.

Currently available options are:

  • PNG – ideal for websites, documents, and social media
  • SVG – perfect for printing, large formats, and professional processing

Before final deployment, we recommend testing the QR code with several devices. This ensures that all information has been correctly stored and that the code can be reliably scanned.

What types of QR codes can you create?

Not every QR code serves the same purpose. While some users merely want to link to a website, others need a digital business card, quick Wi-Fi access, or direct access to a WhatsApp chat. That's why Louvion's free QR code generator supports various QR code types for private and business applications.

Each QR code is created to suit its specific purpose and can then be individually designed and downloaded as a PNG or SVG.

QR Code Type
Area of application
  • Website
  • Contact (vCard)
  • WhatsApp
  • Social Media
  • Email
  • Phone
  • WLAN
  • Text
  • Opens any website
  • Saves contact data directly to the smartphone
  • Starts a chat with a phone number
  • Links to profiles or company pages
  • Automatically creates a new email
  • Directly initiates a call
  • Automatically connects devices to a Wi-Fi network
  • Displays any text after scanning

Website QR Code

A website QR code is one of the most frequently used variations. After scanning, the linked website opens immediately in the user's browser, eliminating the need to manually type long web addresses.

This QR code is particularly often used for:

  • Company websites
  • Online shops
  • Landing pages
  • Menus
  • Product pages
  • Application documents
  • Portfolios
  • Event pages

Contact QR Code (vCard)

With a contact QR code, personal or business contact details can be saved directly on the smartphone. After scanning, the contact can be added to the address book with just a few clicks.

Depending on your needs, the following information can be stored, among others:

  • First and last name
  • Company
  • Position
  • Phone number
  • Email address
  • Website
  • Address
  • Social media profiles
  • Notes

Especially on business cards, this solution saves time and creates a professional impression.

WhatsApp QR Code

After scanning, a WhatsApp QR code directly opens a chat with the stored phone number. Users do not have to save the number first or enter it manually.

This variant is suitable for, for example:

  • Customer service
  • Appointment scheduling
  • Support
  • Orders
  • Small businesses
  • Freelancers

Social Media QR Code

With a social media QR code, visitors are directed straight to your desired profile. This is particularly practical for companies, content creators, or freelancers who want to increase their reach.

Supported platforms include:

  • Instagram
  • Facebook
  • LinkedIn
  • TikTok
  • YouTube
  • Pinterest
  • X (formerly Twitter)

Email QR Code

After scanning, the user's default email program automatically opens. The recipient's address is already pre-filled and can be supplemented with a subject if desired.

This variant is excellent for:

  • Support inquiries
  • Contact forms
  • Quotation requests
  • Applications

Phone QR Code

A phone QR code directly initiates a call to the stored phone number. Especially on vehicles, flyers, or advertisements, interested parties can thus make contact without detours.

WLAN QR Code

With a WLAN QR code, smartphones or tablets automatically connect to your Wi-Fi network. Network name and password no longer need to be entered manually.

This solution is ideal for:

  • Cafes
  • Restaurants
  • Hotels
  • Holiday apartments
  • Offices
  • Waiting areas
  • Trade fairs

Text QR Code

After scanning, the text QR code displays any information directly on the smartphone. It is suitable for short notes, messages, product information, or instructions.

Customize your QR code – colors, logo, and design

A QR code doesn't have to be exclusively black and white. Individual colors, logos, and various design options ensure that the QR code harmonizes with your corporate design while maintaining a professional appearance.

With Louvion's free QR code generator, you can customize the appearance directly during creation and preview the result immediately.

Use your own colors

Customize the foreground and background colors to match your design. In addition to the classic color picker, HEX color codes can also be entered, allowing for the adoption of exact corporate colors.

This is particularly suitable for:

  • Brand appearances
  • Company colors
  • Club colors
  • Events
  • Promotional materials

Always ensure sufficient contrast between the foreground and background. A dark QR code on a light background generally provides the best readability.

Insert your own logo

A logo makes the QR code immediately recognizable and strengthens brand presence. Companies, in particular, use this option on business cards, packaging, or promotional materials.

Suitable examples include:

  • Company logos
  • Club logos
  • Icons
  • Trademarks

Thanks to the integrated error correction, the QR code usually remains easily scannable despite the logo, provided the logo is not chosen too large.

Various QR Code Styles

In addition to colors, the shape of the QR code elements can also be changed. This creates a more modern appearance without restricting functionality.

Depending on your taste, different designs are available – from classic to rounded.

Real-time preview

All changes are displayed immediately. This allows you to try out different colors, logos, and designs before downloading the QR code.

Especially for print projects, this saves time and prevents unnecessary corrections.

PNG or SVG – Which format is the right choice?

After creation, you can download your QR code in different file formats. Which format is most suitable depends on how the QR code will be used later.

The two most important formats are PNG and SVG.

Format
Suitable for
  • PNG
  • SVG
  • Websites, documents, social media, presentations
  • Print products, large formats, professional post-processing

PNG – For digital applications

PNG is a raster image format and is ideal for digital use.

Typical applications include:

  • Websites
  • Online shops
  • PDF documents
  • Presentations
  • Social media
  • Email signatures

The format offers high image quality and is supported by almost all programs.

SVG – For professional printing

SVG is a vector format. Unlike normal image files, it can be scaled up to any size without losing quality.

Therefore, SVG is particularly suitable for:

  • Business cards
  • Flyers
  • Brochures
  • Banners
  • Signs
  • Posters
  • Packaging
  • Exhibition graphics

Graphic programs such as Adobe Illustrator, Affinity Designer, or Inkscape can also process SVG files without problems.

Which format should you choose?

If your QR code is used exclusively digitally, the PNG format is sufficient in most cases.

However, if the QR code is to be printed or further processed later, the SVG format is recommended. It always delivers razor-sharp results regardless of size and is therefore the first choice for professional print products.

Both formats can be downloaded directly after creation, so you can immediately use the appropriate QR code for your project.

What are QR codes suitable for?

QR codes have long been an integral part of everyday life and are used in almost every industry. They connect printed and digital content, allowing information to be provided within seconds. A quick scan with a smartphone is enough to open websites, save contact details, or access further content.

Whether for businesses, self-employed individuals, associations, or private persons – QR codes offer numerous application possibilities and can be flexibly adapted to different requirements.

QR Codes on Business Cards

One of the most popular applications is the integration of a QR code on business cards. Instead of painstakingly typing out contact details, interested parties can simply scan the code and save all information directly to their smartphone.

Depending on needs, the following can be stored:

  • Contact details (vCard)
  • Company website
  • LinkedIn profile
  • Instagram profile
  • Online appointment booking
  • Portfolio
  • Application documents

Especially for self-employed individuals, freelancers, and businesses, this solution creates a modern and professional impression.

QR Codes for Flyers and Brochures

Flyers and brochures often offer only limited space for information. A QR code creates the ideal connection between print and online media.

After scanning, interested parties can go directly to, for example:

  • Landing pages
  • Product pages
  • Price lists
  • Image videos
  • Contact forms
  • Online shops

This keeps printed products clear while simultaneously providing significantly more information.

QR Codes for Restaurants and Cafes

Many catering establishments use QR codes to provide digital menus. Guests can scan the code directly at the table and immediately access the current menu.

QR codes are also suitable for:

  • Drink menus
  • Daily specials
  • Reservations
  • Reviews
  • WLAN access

Particularly practical: changes to the linked website immediately affect all printed QR codes, provided a website is referenced.

QR Codes for Businesses

Companies use QR codes in almost all areas.

Typical applications include:

  • Product packaging
  • Instruction manuals
  • Exhibition stands
  • Shop windows
  • Invoices
  • Offers
  • Business equipment
  • Promotional materials

This allows customers to access further information directly or to make contact.

QR Codes for Events

QR codes have also become indispensable in the event sector.

They are suitable for, for example:

  • Event information
  • Ticket pages
  • Registrations
  • Site maps
  • Programs
  • Social media channels

This gives visitors all important information with just one scan.

QR Codes for Private Use

There are also numerous applications in the private sector.

Examples include:

  • WLAN access for guests
  • Digital photo albums
  • Invitations
  • Birthdays
  • Weddings
  • Family celebrations
  • Contact details
  • Personal websites

A QR code saves time and makes information quickly accessible.

Tips for easily scannable QR codes

A QR code only fulfills its purpose if it can be scanned reliably. Even small design errors can make it difficult or impossible for smartphones to recognize the code.

With a few simple basic rules, you can ensure that your QR code works flawlessly on as many devices as possible.

Choose sufficient contrast

The most important factor is high contrast between the foreground and background.

Ideal are:

  • black QR code on a white background
  • dark colors on light backgrounds

Avoid:

  • light colors on a light background
  • similar color shades
  • strong transparencies

The greater the contrast, the easier it is for the smartphone camera to recognize the QR code.

Do not print QR code too small

A QR code that is too small makes scanning considerably more difficult.

As a rough guide:

Area of application
Recommended minimum size
  • Business card
  • Flyer
  • Poster
  • Billboard
  • 20 × 20 mm
  • 25 × 25 mm
  • 35 × 35 mm
  • 50 × 50 mm or larger

The greater the viewing distance, the larger the QR code should be.

Don't make the logo too big

A logo makes the QR code more individual, but it shouldn't cover too much area.

As a general rule:

  • Place the logo as centrally as possible
  • Leave sufficient white space
  • Don't overdo it

This ensures the QR code remains reliably scannable.

Maintain sufficient clear space

There should always be a clear border around the QR code. This "quiet zone" prevents adjacent graphics or text from interfering with recognition.

Therefore, the QR code should never directly touch images, lines, or text.

Test before printing

Before printing large quantities, it is advisable to test the finished QR code on several devices.

Check the following:

  • Android smartphones
  • iPhones
  • various camera apps
  • different lighting conditions
  • Printouts at original size

This way, potential errors can be detected early.

Common mistakes when creating QR codes

Even though a QR code can be created quickly, there are some common mistakes that can impair its function. With the following tips, you can avoid the most common problems in advance.

Wrong or Incomplete Content

The most common mistake is incorrect entry of the stored data.

Therefore, check in particular:

  • Internet address
  • Phone number
  • Email address
  • Wi-Fi password
  • Contact details

Even a small typo can cause the QR code to not function as intended.

Too Little Contrast

Bright colors or striking color gradients may look modern, but they can impair readability.

Therefore, use dark QR code colors and light backgrounds whenever possible.

Poor Print Quality

Blurry printouts or heavily compressed images make scanning significantly more difficult.

For print products, the SVG format is generally recommended, as it remains razor-sharp regardless of size.

Distorting the QR Code

A QR code should never be stretched or compressed. Changes in proportions can cause scanners to no longer recognize the code correctly.

Therefore, always scale the QR code proportionally.

No Function Test

Many problems can be avoided if the QR code is tested before publication.

Scan the finished code with several devices and check whether all stored content opens correctly.

A short test saves a lot of time later and prevents unnecessary reprints or faulty advertising materials.

Are the generated QR codes permanently usable?

Yes. All QR codes created with Louvion's free QR code generator are static QR codes. This means that the embedded information is stored directly in the QR code, and no connection to an external service is required.

As long as the embedded data remains valid – for example, an accessible website or an active phone number – the QR code will continue to function. There are no monthly costs, no subscriptions, and no time limitations.

Static QR codes are particularly suitable for:

  • Business cards
  • Flyers
  • Brochures
  • Product packaging
  • Signs
  • Posters
  • Menus
  • Personal use

However, please note that the content of a static QR code cannot be changed after creation. If, for example, your website or phone number changes, a new QR code must be created.

  • no registration required
  • no storage of your entered data
