You can encode URLs, text, email addresses, phone numbers, Wi-Fi credentials, and more.

Yes, these are static QR codes that never expire. They will work as long as the encoded content is valid.

It is almost always a size or margin problem. In print the code should be at least 2 cm across, and it needs a white quiet zone roughly four modules wide around every edge. Printing dark ink on a plain white background keeps the contrast high enough for phone cameras.

The format allows up to 4,296 alphanumeric characters, but the more you encode the denser the grid becomes and the harder it is to scan. In practice stay under about 300 characters, or store a short link instead of the full text.

Yes, but contrast is what matters. Keep the foreground dark and the background light with a clear brightness gap; pale foregrounds like yellow or a dark background are the usual failure causes. Always test the recolored code with a real phone camera before you publish it.
