Frequently asked questions
Everything you need to know about QRocket and QR codes — pricing, expiry, privacy, file formats and getting a code that scans reliably in print.
Is QRocket free to use?
Yes — QRocket is completely free. There is no account or sign-up, no watermark on your codes, no expiry date and no scan limits. You can create a QR code and download it in full quality without paying anything.
Do QR codes made with QRocket expire?
No. Every code you create with QRocket is a static QR code, which means your content is encoded directly into the pattern itself. It never routes through our servers, so it cannot expire, be deactivated or hit a scan limit — it keeps working for as long as the destination it points to exists. Learn more in our guide to whether QR codes expire.
What is the difference between static and dynamic QR codes?
A static QR code stores your content directly in the pattern, so it works forever and needs no third-party service. A dynamic QR code stores a short redirect link instead, which lets you edit the destination and track scans — but the code stops working if the provider shuts down or a subscription lapses. QRocket makes static codes. See our full comparison of static vs dynamic QR codes.
Can I edit a QR code after creating it?
No — a static QR code is fixed at creation and its content cannot be changed afterward. If you need a different destination, simply generate a new code; it takes seconds and is free. That is also why we recommend double-checking your link before printing. More detail in can you edit a QR code?
Can I use QRocket QR codes commercially?
Yes. You own every QR code you create with QRocket and can use it anywhere — product packaging, menus, ad campaigns, client work — with no attribution required and no licensing fees. The details are in our terms of service.
Is the content I enter private?
Yes. QR codes are generated entirely in your browser — the links, Wi-Fi passwords or contact details you type are never sent to or stored on our servers, and we cannot see what you encode. Saved styles and history live in your own browser's local storage. Read the privacy policy for details.
Are QR codes safe to scan?
The code itself is just a pattern that stores text — it cannot harm your device. The risk is where a code points: scammers sometimes place codes that lead to phishing sites. Preview the URL your phone shows before opening it, and be wary of stickers pasted over original codes. Our guide on QR code safety covers the warning signs.
What types of QR codes can I create?
QRocket supports ten content types: website links, plain text, Wi-Fi networks, contact cards (vCard), email, SMS, WhatsApp messages, phone calls, calendar events and map locations. Pick a type in the generator and the form adjusts to what that type needs. Our overview of QR code types explains when to use each one.
How do I make a Wi-Fi QR code?
Choose the Wi-Fi type in the generator, enter your network name (SSID), select the security type (WPA/WPA2, WEP or open) and type the password. Scanning the finished code connects a phone to the network automatically — no typing needed. See the step-by-step Wi-Fi QR code guide.
What file formats can I download?
You can export your QR code as a high-resolution PNG, a print-ready SVG vector, JPG, WEBP or PDF. SVG scales to any size without losing sharpness, which makes it ideal for professional printing, and the PDF export is prepared at 300 DPI with optional crop marks. Our guide to printing QR codes explains which format to pick.
Can I add a logo to my QR code?
Yes — you can drop a logo into the center of your code directly in the generator. QR codes tolerate a certain amount of covered area thanks to error correction, and QRocket runs a live scannability check so you can see immediately whether your design still reads reliably. See how to add a logo to a QR code.
Can I customize the colors and shape of my QR code?
Yes. You can change the code's colors and pick different module and corner shapes to match your brand. The main rule is contrast: keep the pattern clearly darker than the background, or scanners will struggle. Our QR code colors guide shows which combinations work.
What is QR code error correction?
Error correction is built-in redundancy that lets a QR code scan even when part of it is damaged, covered or dirty. There are four levels — L, M, Q and H — recovering roughly 7% to 30% of the code. Higher levels make the pattern denser but more resilient, which matters if you add a logo or print small. Read more about QR code error correction.
How should I print a QR code, and should I test it first?
Export an SVG or 300 DPI PDF, leave a quiet zone of empty space around the code, and make it at least 2 × 2 cm (about 0.8 inches) for close-range scanning — larger if people scan from a distance. Always test your code on a couple of phones before sending it to print, since static codes cannot be edited later. Our QR code size guide has recommended dimensions by use case.
