Creating a QR code takes only a few seconds, but making one that looks good and scans reliably requires a little more thought. You need to choose the right type of QR code, enter the correct information, select a suitable design, and test the finished code before using it.
The good news is that you don't need any technical knowledge. Modern QR code generators handle the complicated parts automatically, allowing you to create a code for a website, WiFi network, contact card, social profile, PDF, email address and many other types of content.
This guide walks you through the entire process from choosing what your QR code should do to downloading the final file.
What do you need to create a QR code?
In most cases, you only need the information you want to share and a QR code generator.
Depending on the type of code, that information might be:
- a website URL,
- a WiFi network name and password,
- your contact details,
- an email address,
- a phone number,
- a Google Maps location,
- a social media profile,
- a link to a PDF,
- or simple text.
Once you know what you want the QR code to do, the rest of the process is straightforward.
Step 1: Decide what your QR code should do
The first step is choosing the action that should happen when someone scans your code.
A QR code can do much more than simply open a website. Different QR code types are designed for different kinds of information.
Website QR code
A website QR code opens a web page when scanned. This is one of the most common uses and works well for business websites, landing pages, online stores, articles, portfolios and promotions.
WiFi QR code
A WiFi QR code allows guests to connect to a wireless network without manually typing the password.
vCard QR code
A vCard QR code can contain contact information such as your name, company, phone number, email address and website.
Email QR code
An email QR code can open the user's email application with the recipient, subject and even message already filled in.
Phone QR code
A phone QR code opens the phone dialer with your number ready to call.
Social media QR code
You can also create codes that link directly to Instagram, Facebook, LinkedIn, YouTube, TikTok and other social profiles.
The best QR code starts with a clear purpose: decide what you want people to do after scanning it.
Step 2: Enter your information
Once you've chosen the QR code type, enter the information that should be encoded.
For a website QR code, this might simply be:
https://example.com
For a WiFi code, you'll typically need:
- the network name,
- the WiFi password,
- and the security type.
For a digital business card, you might enter your name, job title, company, phone number, email address and website.
Always check the information carefully before downloading or printing your code. A QR code can encode exactly what you enter, including mistakes.
Step 3: Generate the QR code
After entering your information, the generator converts it into a QR code pattern.
The black and white squares you see are not random. They represent the encoded information in a format that cameras and QR scanners can quickly read.
With BestQR, the QR code preview is generated directly in your browser, allowing you to see the result immediately while you customize it.
Step 4: Choose your colors
A QR code doesn't have to be black and white. You can customize the colors to better match your website, company or brand.
However, readability should always come before appearance.
The safest combination is:
- a dark QR code,
- on a light background,
- with strong contrast between the two.
Avoid using colors that are too similar. For example, a light gray QR code on a white background may look elegant but can be difficult for some cameras to detect.
Step 5: Customize the QR code shape
QR codes can be styled in different ways while keeping the encoded information intact.
Depending on the generator, you may be able to customize:
- the shape of the individual dots,
- the corner squares,
- the corner dots,
- background colors,
- and other visual details.
Rounded or stylized elements can make a QR code feel less technical and help it fit more naturally into a modern design.
Just avoid excessive customization that reduces contrast or makes important parts of the code difficult to read.
Step 6: Add your logo
Adding a logo to the center of a QR code is a simple way to make the design more recognizable.
A business might add its company logo, while a personal QR code could use a profile image or brand icon.
QR codes include error correction, which means part of the pattern can be covered while the code remains readable. This makes it possible to place a reasonably sized logo in the middle.
However, the logo should not cover too much of the code.
For best results:
- keep the logo centered,
- avoid making it excessively large,
- use a clear image,
- maintain enough contrast around it,
- and always test the final QR code.
Step 7: Keep enough white space around the QR code
The empty area surrounding a QR code is known as the quiet zone.
This space helps scanners identify where the QR code begins and ends. If text, graphics or other design elements are placed too close to the pattern, scanning can become less reliable.
When adding a QR code to a poster, business card, menu or product package, leave a clear margin around all four sides.
Step 8: Test your QR code
Never print or publish an important QR code without testing it first.
Open the camera app on your smartphone and scan the code directly from the screen.
Check that:
- the code is detected quickly,
- the correct website or action opens,
- the information is accurate,
- and the destination works properly.
If possible, test the QR code with more than one device. Trying both an iPhone and an Android phone can help catch potential problems before the code is printed.
A QR code isn't finished until you've scanned and tested it yourself.
Step 9: Choose PNG or SVG
Once you're happy with your QR code, you'll need to choose a file format.
The two most common options are PNG and SVG.
PNG
PNG is a standard image format that works almost everywhere. It's a convenient option for websites, presentations, social media graphics, documents and many common printing situations.
A sufficiently high-resolution PNG can produce excellent results for most everyday uses.
SVG
SVG is a vector format. Unlike a regular image, it can be enlarged without becoming blurry or pixelated.
This makes SVG particularly useful for:
- large posters,
- banners,
- signage,
- professional printing,
- and graphic design software.
If you're unsure, PNG is usually convenient for normal digital use, while SVG is an excellent choice when the QR code may need to be resized significantly.
Step 10: Download your QR code
After choosing the file format, download the finished QR code to your device.
Before placing it into your final design, scan the downloaded version one more time. This is especially important if you've resized or edited the image after downloading it.
How big should a QR code be?
There is no single perfect QR code size because the correct size depends on how far away people will scan it.
A QR code printed on a business card can be relatively small because the user will hold the card close to their phone.
A QR code on a poster, shop window or billboard needs to be much larger because people may scan it from farther away.
As a general rule, increase the QR code size as the expected scanning distance increases.
How to create a QR code for a website
Creating a QR code for a website is one of the simplest examples.
- Open the website QR code generator.
- Enter your complete website URL.
- Customize the colors and design if desired.
- Add your logo if you want branded artwork.
- Scan the preview with your phone.
- Download the finished QR code as PNG or SVG.
When someone scans it, their phone will offer to open the encoded website.
How to create a QR code for WiFi
A WiFi QR code is useful in homes, offices, hotels, cafés, restaurants and rental properties.
- Open the WiFi QR code generator.
- Enter the WiFi network name.
- Enter the password.
- Select the correct security type.
- Generate and test the QR code.
- Print or display it where guests can easily scan it.
Instead of asking for the password and typing it manually, visitors can simply scan the code.
How to create a QR code for a business card
There are several ways to add a QR code to a business card.
You could link to:
- your company website,
- your personal portfolio,
- your LinkedIn profile,
- or a digital contact card.
A vCard QR code is particularly useful because it lets someone save your contact information without manually typing your name, phone number or email address.
How to create a QR code for a PDF
A QR code cannot normally contain an entire PDF file directly. Instead, the PDF needs to be available online, and the QR code contains the link to that file.
This is useful for:
- restaurant menus,
- product manuals,
- brochures,
- price lists,
- event programs,
- and downloadable documents.
You can use the PDF QR code generator to turn the document URL into a scannable code.
How to create a QR code for social media
A QR code can provide a simple bridge between offline materials and your social media profile.
You can place one on:
- business cards,
- product packaging,
- store displays,
- event materials,
- posters,
- restaurant menus,
- or printed advertisements.
After scanning the code, users can go directly to your profile instead of searching for your username.
Common QR code mistakes to avoid
QR codes are generally reliable, but a few common mistakes can make them difficult or impossible to scan.
Low contrast
Avoid combinations where the QR pattern and background are too similar.
Making the QR code too small
A tiny code may work on your computer screen but become difficult to scan after printing.
Removing the quiet zone
Always leave some empty space around the QR code.
Using a blurry image
Low-resolution screenshots can become blurry, especially when enlarged. Use a high-quality PNG or SVG instead.
Adding an oversized logo
A logo that covers too much of the QR pattern can exceed the code's error correction capabilities.
Not testing before printing
This is one of the easiest mistakes to avoid. Scan the final file before ordering flyers, menus, packaging or other printed materials.

Frequently Asked Questions
Do I need an app to create a QR code?
No. You can create a QR code directly in a web browser using an online QR code generator.
Do people need an app to scan my QR code?
Usually not. Most modern iPhones and Android phones can recognize QR codes directly through the built-in camera application.
Can I change a QR code after downloading it?
You can change its visual size or place the image inside another design. However, the information stored inside a static QR code cannot be changed without generating a new code.
Can I use a QR code commercially?
Yes. QR codes can be used on business cards, menus, products, advertising materials, packaging, signs and other commercial materials.
How many times can a QR code be scanned?
A standard static QR code does not have a built-in scan limit and can be scanned repeatedly.
Will my QR code expire?
A static QR code itself does not expire. It will continue to contain the same information as long as the code remains readable. If it links to a website, that website must still be available.
Creating a QR code is simple: choose what you want to share, enter the information, customize the appearance, test the result, and download the finished file.
The most important step is testing. A beautiful QR code is useful only if people can scan it quickly and reach the correct destination.
