About the Password Generator

Password Generator builds a cryptographically random password with the mix of characters you need — length, uppercase, lowercase, numbers and symbols — all controlled by simple sliders and checkboxes.

How to use

Pick a length (14-20 is the sweet spot for most accounts).
Tick the character classes to include.
Click Generate and copy the result straight into your password manager.

Benefits & key features

Uses crypto.getRandomValues — true browser-grade randomness.
Customisable rules fit even the strictest corporate password policy.
Nothing is stored or logged — what you see is what you get.
Works offline; great when rotating server-root credentials.

Pro tip

Longer beats complex. A 20-character lowercase-only password is stronger than a 10-character mess of symbols. Combine length + randomness for the best results.

Why choose toolsfy for Developer tools?

Developers already have editors, linters and one-off scripts that do half of what these utilities do — but nobody wants to paste a JWT into a random cloud decoder, or send an AES-encrypted sample through someone else's server. toolsfy's dev utilities are deliberately tiny, zero-dependency and 100% client-side so they can become part of a muscle-memory workflow you actually trust with production data.

Common use cases

Full-stack developers formatting a gnarly production JSON payload to figure out which field the front-end is mis-parsing.
DevOps engineers minifying a snippet of JavaScript or CSS inline during a code review, without reaching for a Node build step.
Security engineers hashing or Base64-encoding a small test vector for a quick regression check on an authentication flow.

Frequently asked questions

Do these tools send my code or payload to a server?

No. Everything runs inside this tab. Even large minification jobs stay local — you can run the tool with DevTools → Network tab open to confirm.

Is the output deterministic and reproducible?

Yes. The same input always produces the same output, because the libraries are versioned (the exact CDN versions are pinned in common.js).

Can I integrate the underlying logic into my own project?

The tools rely on well-known open-source libraries (js-yaml, pdf-lib, clipboard API). Swap toolsfy for the npm packages of the same libraries once you are ready to automate.
