Generate QR Codes for URLs, Menus, and Text
With the SizeHex QR Code Generator, you can easily create high-quality QR codes for virtually any digital destination. Common use cases include website URLs for marketing flyers, plain text messages for scavenger hunts, Wi-Fi passwords for Airbnb guests, or digital vCard business cards. Because the rendering engine is built directly into your browser, the generation is instantaneous without any annoying server loading screens.
Do SizeHex QR Codes Expire?
Absolutely not! Many commercial online QR generators create what are known as "Dynamic" QR codes. These dynamic codes actually point to the company's own tracking servers first, which then redirect to your link. This means if you stop paying for their subscription, your QR code will break and become useless. SizeHex only generates Static QR Codes. The data you enter is mathematically encoded directly into the black and white pattern of the image itself. This means your QR code is completely permanent, will never expire, and will work forever without any hidden subscription fees.
Privacy First Generation
We believe your data should remain yours. The text or URLs you input to generate the QR code are processed entirely within your local browser's memory using secure JavaScript libraries. We do not track, store, or log the data you encode, making this the absolute perfect tool for generating QR codes for sensitive internal company links or personal contact information.
Creative Use Cases for QR Codes
- Restaurant Menus: Generate a QR code that links to your digital menu. Print it on table cards or stickers so diners can scan and view the full menu on their phones.
- Event Tickets & Check-ins: Create a QR code containing an event registration link or confirmation number for fast, contactless check-in.
- Business Cards: Replace or supplement paper business cards with a QR code that links to your LinkedIn profile, portfolio, or vCard contact file.
- Guest Wi-Fi Sharing: Generate a Wi-Fi QR code that guests can scan to connect automatically โ no need to read out long passwords.
- Product Packaging: Add a QR code to product packaging linking to instructional videos, warranty registration, or brand websites.
- Marketing Flyers & Posters: Add a scannable QR code to print advertising that links users directly to a landing page, promotion, or app store download.
Frequently Asked Questions
No! We generate static QR codes, meaning the actual URL or text is mathematically encoded directly into the image pixels. It does not rely on our servers, so it will never expire or break.
Yes, 100% free. There are no subscriptions, no hidden tracking, and no watermarks on your downloaded QR code image.
You can use it to share website links on printed flyers, direct restaurant customers to a digital menu, share Wi-Fi credentials, or quickly pass contact information.
Yes. Because our QR codes are static and don't redirect through third-party tracking servers, they are completely safe. They will direct the user exactly to the text or URL you entered.
To create a Wi-Fi QR code, select the "WiFi" input type in our QR generator, then enter your network name (SSID), password, and security type (WPA, WEP, or Open). The generated QR code, when scanned by a smartphone, will automatically prompt the user to connect to your network โ no manual password typing required. Your Wi-Fi credentials are processed entirely in your browser and never sent to any server.
SizeHex generates QR codes as high-resolution PNG images. For most print applications like business cards, flyers, and posters, the downloaded PNG is more than sufficient. For very large format printing (banners, billboards), we recommend scaling the PNG up using a vector conversion tool to avoid pixelation at very large sizes.
The minimum recommended size for a printed QR code is about 2cm x 2cm (0.8" x 0.8") for close-range scanning with modern smartphones. Smaller than this may cause scanning failures on older devices. A good rule of thumb is: QR code size = scan distance รท 10. So for a code to be scanned from 1 meter away, it should be at least 10cm wide.
