Free Online Generators

Generators create something new from a small set of inputs — a QR code from a link, a password from a set of character rules, or a random number from a range. Randomness here is sourced from your browser's cryptographically secure random number generator where it matters (like passwords), not a predictable pseudo-random fallback.

Common uses

How to choose

These three generators solve different problems, even though they're grouped together. The Password Generator is the only one where the source of randomness genuinely matters for security — it uses crypto.getRandomValues(), not a cosmetic random-looking string, so the output is suitable for actual account passwords. The QR Code Generator isn't about randomness at all — it's an encoding tool that turns any text, URL, or Wi-Fi credential into a scannable image, with a one-click PNG download. The Random Number Generator is the simplest of the three: pick a minimum and maximum, and it draws a single value or a batch from that range, useful for raffles, sampling, or picking a winner from a numbered list.

A common mistake is assuming any "random" output on the web is equally trustworthy. It isn't — a random number picked for a raffle doesn't need cryptographic-grade randomness, but a password does, which is why the Password Generator specifically avoids Math.random() (a fast, predictable algorithm never intended for security purposes) in favor of the browser's dedicated crypto API.

Frequently asked questions

Are the passwords generated here secure?

Yes — passwords are generated using crypto.getRandomValues(), your browser's cryptographically secure random source, not Math.random().

Are generated passwords stored or transmitted anywhere?

No. Passwords are generated and displayed locally; nothing is sent to a server or logged.

Can I download the QR code I generate?

Yes, the QR Code Generator includes a one-click PNG download once your code is created.
