About Miscellaneous Tools

Everyday utilities: QR codes, strong passwords, list randomisers, and PDF tools.

A category for the tools that do not fit neatly anywhere else but are useful every day. The QR code generator creates custom QR codes for URLs, WiFi credentials, contacts, and text, with downloads as PNG or SVG. The password generator uses cryptographic randomness and never stores what it outputs. The list randomiser runs a fair Fisher-Yates shuffle for giveaways, team picks, and raffles, with a shareable results URL. The PDF utilities let you merge, split, and compress documents without uploading anything: pdf-lib runs entirely in your browser, which keeps contracts, invoices, and personal records private. For test data, our IBAN generator produces correctly-formatted-but-not-real international bank account numbers to help QA teams build payment flows without using real financial data.

Frequently asked questions

Are the passwords and QR codes generated on my device?
Yes. Every tool in this category generates its output locally. Nothing is transmitted to our servers.
How random is the password generator?
It uses the browser's crypto.getRandomValues API, which is a cryptographically secure random number generator suitable for passwords, tokens, and keys.
Can I upload a sensitive PDF to merge or split it?
You do not upload it. Our PDF tools use a library called pdf-lib that runs in JavaScript inside your browser. The file never touches our servers.
Is the IBAN generator safe to use?
Yes, with a clear caveat: it produces numbers that look valid to the format checker but are not real accounts. Use them only for testing payment systems, never to impersonate a real customer or commit fraud.
