Generators
QR Code Generator and Password Generator are the two tools people reach for most in this category, and both matter more than they look: a QR code is only as reliable as the data encoded in it, so double-check the URL or text before generating one for print — a mistake is expensive to fix once it's on a flyer or a product label. A generated password's strength comes almost entirely from length and randomness rather than complexity rules; a random 16-character password is dramatically harder to guess than a shorter one stuffed with symbols, which is why the length slider matters more than which character sets you tick.
Color Code Converter converts between HEX, RGB and HSL for designers and developers who need the same color expressed in a different format, and Lorem Ipsum Generator produces placeholder paragraphs for mockups and layout testing before real copy is ready.
QR codes and passwords: two small tools, two common mistakes
Frequently asked questions
Are generated passwords stored anywhere?
No. Passwords are generated using your browser's random number generator and shown to you once — nothing is transmitted or logged. Copy it somewhere secure, ideally a password manager, right away, since closing the tool loses it.
Do QR codes expire?
A QR code generated here simply encodes a fixed piece of text or a URL — it doesn't expire and isn't tied to a Toolnova account. If it points to a URL, the code stays scannable for as long as that URL stays live.
