Technical Overview & Use Cases

This generator renders high-quality QR codes through a privately operated Cloudflare Worker that we control end-to-end. The encoded text never leaves the FAK LAB infrastructure — no third-party services, no analytics, no logging of payloads. It supports multiple data formats including plain text, URLs, WiFi network credentials, email links, phone numbers, SMS messages, and vCard contacts. Error correction levels (L/M/Q/H) allow scanning even with partial damage.

• Marketing & Business: Generate QR codes for websites, promotional links, or business cards that customers can scan instantly with their phones.
• WiFi Sharing: Create a QR code with your WiFi credentials so guests can connect without typing the password manually.
• Contact Sharing: Generate vCard QR codes that add your full contact information to someone's phone with a single scan.

Privacy & Security Guarantee

This tool is part of the FAK LAB ecosystem, founded by Faizan Ahmad Khan Khichi. QR rendering runs on our own Cloudflare Worker which only accepts requests from HTTPS origins. We never store the data you encode and the worker keeps no logs of your input.

Frequently Asked Questions

What is error correction and which level should I choose?

Error correction allows a QR code to remain scannable even if partially damaged. Level L (7%) is fine for digital use, M (15%) for printed materials, Q (25%) for outdoor use, and H (30%) if you plan to add a logo overlay.

Can I use custom colors for my QR code?

Yes. Use the color pickers to set custom foreground and background colors. Ensure sufficient contrast between them for reliable scanning — dark foreground on light background works best.

What's the maximum data a QR code can hold?

A QR code can store up to ~4,296 alphanumeric characters or ~2,953 bytes of binary data. For best scanning performance, keep content concise — shorter URLs and text produce simpler, more reliable codes.
