What is a QR code?
QR codes can contain URLs, Wi-Fi connection details, text, email details, phone numbers or SMS information.
Scanning can open a website, connect to Wi-Fi, show text, compose an email, open the phone dialer or compose an SMS.
QR Code is a registered trademark of DENSO WAVE INCORPORATED.
Static QR codes
Codes created by this tool contain the URL or information you enter directly. To change the content, create a new QR code. Codes with fixed content like this are often called static QR codes.
Where QR codes can help
QR codes can be used for shop information, business cards, flyers, reception desks, inquiries and more.
From a flyer or business card to a website
Create a code for a shop website, booking page, product information or social profile so users do not have to type a long URL.
Wi-Fi information for shops and venues
Reduce manual entry of SSIDs and passwords for guest Wi-Fi in cafes, hotels, rentals, meeting rooms and offices. Anyone who can see a Wi-Fi QR code can read its connection information. Check where you display it and which network it provides access to.
Display short text directly
Use a code for reception numbers, exhibit descriptions, event meeting points or brief instructions without creating a web page.
Make email inquiries easier
An email QR code can include the recipient, subject and body, reducing typing errors and the work of composing a message from scratch.
Phone bookings and contact numbers
A phone QR code can open the phone app with the number entered, depending on the device.
Arrival notices and standard messages
An SMS QR code can open a message with a recipient and preset text for arrivals, pickups or event check-in. Actual behavior may differ by operating system and SMS application.
Scanning tips
Before printing or publishing, check scanning on actual smartphones. A black code on a white background with sufficient margins is recommended. Avoid printing too small. Longer content makes the code denser, so choose a larger image. Colored or inverted codes need additional checks. The absence of warnings does not guarantee scanning.
Rounded or round dots and transparent backgrounds may require more favorable scanning conditions than standard square codes. Place the code on the intended background, at its intended size and on the intended material, and test with several devices.
FAQ
Can I create QR codes for free?
Yes. QR code creation is free and requires no sign-up.
Is my input saved?
No. Input and QR codes are processed in your browser and are not sent to or stored on Qvernal's server.
Can I change the content after creating a code?
The content in a QR code created by this free tool cannot be changed afterward. To change it, create a new QR code.
Do QR codes expire?
The QR code itself has no expiration date. However, a linked URL may stop working if its destination is deleted or changed.
Can I use QR codes commercially?
Yes. QR codes conforming to JIS and ISO standards do not require a usage fee or application, including for commercial use. You remain responsible for checking linked destinations, published content, third-party rights and the terms of services you use. Test scanning on real devices before publishing or printing.
Official external information: consult the DENSO WAVE FAQ for QR code usage conditions.
What is the difference between PNG and SVG?
PNG is convenient as a standard image. SVG scales without the same loss of quality, making it useful for printing and design editing.
Can I choose any colors?
To avoid combinations that are difficult to scan, Qvernal offers color themes chosen with readability in mind instead of unrestricted colors.
Can I use brand colors outside the themes?
Not currently. To prioritize scanning in published and printed materials, you can choose from combinations with sufficient contrast between the code and its background.
Which color combination is easiest to scan?
In general, the Standard theme with a dark code on a white background is the safest choice. Test other themes on real devices before publishing or printing.
Can rounded QR dots still be scanned?
They may scan, but results depend on the device, amount of content, colors, size and print conditions. Qvernal keeps the three corner finder patterns square and uses settings that prioritize readability for styled codes. Test on several devices before publishing.
Can I make the background transparent?
Yes. PNG and SVG backgrounds can be transparent. Scanning may be harder if the background behind the code is dark, patterned or has too little contrast. Test the code in its final placement.
Does changing the design change the content?
The URL or text you entered does not change. However, you must generate a new image after changing the design.
Where is my downloaded QR code?
It is saved to the download location configured in your browser or device. Check apps or folders such as Downloads, Files or Photos.
Can I make a QR code for an image or PDF?
The image or PDF itself is not stored in this QR code. Put the file somewhere it can be shared, then create a QR code for its URL. Check the file's visibility and access permissions.
Do Wi-Fi QR codes work on every device?
Behavior depends on the operating system, camera app and Wi-Fi settings app. Test scanning on the devices you intend to use.
What should I do if a code will not scan?
Return to a black code on a white background, choose Standard or Wide margins, and increase the image size. Test on several devices before publishing.

QR code cautions and responsibilities
This tool converts the information you enter into a QR code in your browser. Qvernal does not guarantee that a generated QR code's content is accurate, complete, current, lawful, non-infringing or suitable for a particular purpose, or that it will scan correctly and perform the intended action on every device, operating system, application, camera, printed material or installation environment.
- Before publishing, printing or distributing a code in a shop, on a business card, flyer, product, sign or other medium, test it on several devices at the actual size, color, material and installation conditions. Check the scan result, encoded information and destination.
- You are responsible for checking the accuracy of URLs, text, email addresses, phone numbers, SMS, Wi-Fi details and other input, your authority to publish it, third-party copyright, trademark, privacy and other rights, applicable laws, and the terms of relevant services.
- Do not use generated QR codes for fraud, phishing, impersonation, directing people to unauthorized access, distributing malware, infringing third-party rights or other unlawful or improper purposes. Users engaging in unlawful or improper use are responsible for addressing resulting problems and disputes.
- Dot shapes, colors, transparent backgrounds and other design settings may reduce scanning performance. Even without a warning, scanning is not guaranteed. Test with the actual background, size, material and printing conditions on several devices.
- Wi-Fi QR codes contain connection information such as the SSID and password. If displaying them where others can see them, consider using a guest network, limiting display locations and changing credentials periodically.
- How phone, email and SMS actions open depends on the device, operating system and application. Call charges, SMS charges, data charges or other costs may apply.
- This tool creates static QR codes that directly contain the input. Their content cannot be changed after publication or distribution. If the content changes, create a new code and replace existing printed or displayed copies.
- Input and generated QR codes are not sent to or stored on Qvernal's server. Qvernal therefore does not restore generated codes, change their content, stop their distribution or manage their linked destinations.
Review these notes and use your own judgment when using, publishing, printing or distributing generated codes. For site-wide information, also review Qvernal's Disclaimer.
