常见问题
- Does my data get uploaded?
- No. Both encoding and decoding happen entirely in your browser. The text you encode and the images you scan never leave your device.
- What can I encode in a QR code?
- Any UTF-8 text, including URLs, plain text, Wi-Fi credentials (SSID + password), email links (mailto:), phone numbers (tel:), and so on. Most apps treat URLs specially.
- What image formats can I decode?
- PNG, JPG, WebP, GIF, BMP — basically anything your browser can render. Decoding works on screenshots, scans, and phone-camera photos.
- Why doesn't decoding always work?
- QR decoding needs reasonable contrast, focus, and resolution. Very small QR codes, heavy compression artifacts, or perspective distortion can fail. Try a sharper or higher-resolution image.
