Free QR code generator for URL, Wi-Fi, vCard, email, SMS, phone, and events
TechMamba QR Code Generator creates static, scannable QR codes locally in your browser with custom colors, size, quiet zone, and error correction.
Use it for business cards, restaurant menus, product packaging, Wi-Fi sharing, event invites, landing pages, printed flyers, customer support flows, internal operations, and offline-to-online campaigns.
Generated QR codes can be exported as PNG for quick sharing or SVG for print and design workflows. For best results, keep strong contrast, leave enough margin, and test the code before publishing or printing.
QR Code Generator FAQ
What can I create with this QR code generator?
You can create QR codes for website URLs, plain text, Wi-Fi login details, vCard contacts, email drafts, SMS messages, phone numbers, and calendar events.
Is this a static QR code generator?
Yes. The tool creates static QR codes where the data is encoded directly into the image. Static QR codes do not require an account and do not expire, but the encoded content cannot be edited after download.
Can I create a Wi-Fi QR code?
Yes. Select Wi-Fi, enter the network name, password, security type, and hidden network setting, then download the QR code.
Can I create a vCard QR code for a business card?
Yes. Choose the vCard option and enter the contact name, company, phone, email, website, and address. People can scan the QR code to save the contact details.
Should I use PNG or SVG?
Use PNG for websites, chats, documents, and quick sharing. Use SVG for print, design tools, signage, packaging, and large-format assets because SVG scales cleanly.
How do I make a QR code easier to scan?
Use high contrast colors, keep a clear quiet zone margin, avoid tiny printed sizes, and test the QR code before publishing.
What is QR code error correction?
Error correction helps a QR code remain scannable if part of it is slightly damaged, blurred, dirty, or visually customized. Higher error correction can improve resilience but may create a denser code.
Do generated QR codes expire?
The static QR codes generated here do not expire. A QR code can stop working if its encoded destination, such as a webpage, is removed or changed.
Can I edit a QR code after downloading it?
Static QR codes cannot be edited after download because the destination or payload is embedded in the code. To change the destination later, use a redirect URL that you control before generating the QR code.
Can I customize QR code colors?
Yes. You can choose foreground and background colors, but strong contrast should be maintained for reliable scanning.
Does this QR code generator upload my data?
No. QR code generation happens locally in your browser. The content you enter is used to draw the QR code on the page and is not uploaded to TechMamba servers.
What size should I print a QR code?
Print size depends on scan distance and content density. For business cards and close-range scans, keep the code large enough to scan comfortably, maintain a quiet zone, and test it with multiple phones before printing in bulk.
