Utilities Tools — 40 free tools

Free Online Utilities

The everyday utilities that save a trip to a sketchy ad-filled site: generate QR codes and strong passwords, spin a wheel to pick a name, build UTM links, create invoices and rent receipts, validate PAN/GSTIN/IFSC details, and inspect technical things like DNS records or HTTP headers.

Generators run on cryptographically secure randomness where it matters (passwords, picks), validators implement the actual official checksum rules, and document generators produce clean print-ready output.

Every utility is free with no signup. Most work entirely offline once loaded, and none of them watermark or limit what you create.

Common questions

Are the generated passwords and random picks truly random?

Yes — they use your browser's crypto.getRandomValues, the same cryptographically secure source used for security keys, not predictable Math.random().

Do the validators (PAN, GSTIN, IFSC) check against official databases?

They validate format and checksum per the official specification instantly in your browser. That catches typos and fakes with wrong structure; it does not query government databases.

Can I use generated invoices and receipts commercially?

Yes. Everything you create with the generators is yours to use — there is no watermark, attribution requirement, or license restriction.
