$ cat FAQ.md
What can I encode in a QR code?▶
Any text, URL, email address, phone number, Wi-Fi credentials, or other data up to about 4,000 characters depending on error correction level.
What is error correction level?▶
QR codes have built-in error correction. L recovers ~7% damage, M ~15%, Q ~25%, and H ~30%. Higher levels make the QR code larger but more resilient to damage or obstruction.
Can I customize the colors?▶
Yes. Choose from presets or pick custom foreground and background colors. Make sure there is enough contrast for scanners to read the code.
Is my data uploaded?▶
No. QR codes are generated entirely in your browser. Your text never leaves your device.
