Hey Product Hunt 👋 I kept hitting the same wall: I need to convert a unit or generate a QR code, I search, and I land on a page that wants my email or worse, one that POSTs my input to a server to compute a percentage. So I built the boring alternative. Tools4Free is a set of small utilities where everything runs in the browser. No account, no ads, no analytics on your input. If you want to verify that: open the network tab, or just turn your wifi off after the page loads. It keeps working. What's in there right now: unit converters, percentage and BMI calculators, a QR generator, a password generator, fancy text, and a few others. It's translated into several languages. What I'm honestly unsure about: - The QR error-correction picker is still a raw L/M/Q/H dropdown, which means nothing unless you've read the spec. I don't know how to present that to a normal human. - I have no idea which tools people actually want next. My list is based on what I personally needed, which is a sample size of one. If you use one of these regularly and it's missing, tell me that's genuinely the most useful thing I can get out of today. Ping me here, I'm around all day.
