Yes. QR codes generated here are free to use anywhere, including commercially, with no licence or attribution.

No. These are static QR codes — the data is encoded directly in the image, so they work forever and never expire.

A website link, plain text, an email, a phone number, Wi-Fi credentials, a location and more — anything that fits as text.

On most phones, just open the camera app and point it at the code — a notification appears to open the link or content.

Finding out how big a thing will be before you make it: how many gigabytes an hour of footage takes, how long a file needs on the connection you have, how large a photo prints before it goes soft, what bitrate fits the budget you were given.

Reading a figure in one unit next to a figure in another. Megabits are not megabytes and the eight-fold gap sinks most transfer estimates; a kilobyte is 1 000 bytes to a drive maker and 1 024 to the operating system; pixels are not dots per inch. None of it is hard arithmetic — the unit on each side is what decides whether the answer means anything.

ASCII code converter, HTTP Status Code Reference and Morse code translator share its section. They are not variants of it — being filed together is not the same as being alike — but that is where to look if this turned out not to be the tool you wanted.

Byte prefixes follow the IEC convention where a kibibyte is 1 024 bytes and a kilobyte is 1 000 — drive makers use the second, operating systems often report the first, and a disk that shrinks on arrival is that gap and nothing else. Print sizing assumes 300 dpi unless you change it.
