Why This Site Exists
Most free tool sites are not really free. They hide your file behind a sign up, stamp a watermark on the result, stop you after three tries, or quietly send a private document to a server you know nothing about and cannot ask about later.
WizTools is the plain opposite of that. There are 405 tools here in 18 groups, and every single one is complete. No tier, no credit counter, no account, no watermark. If a tool is on the list, the whole tool works.
It started with a small, ordinary annoyance. You want one number and the internet makes you work for it. So we built the boring version: open the page, type your numbers, read the answer, close the tab. That is still the whole idea.
Is WizTools safe to use?
Yes, and it is worth saying why rather than just claiming it. About 78 of the tools here never send anything anywhere. The calculators and converters are JavaScript running on your own machine, so your numbers stay on your device. There is no upload, which means there is no copy of your work on a server for anyone to leak, lose or sell.
That is also why these tools keep working when your internet drops in the middle of a job, and why we could not read what you typed even if somebody asked us to.
A few tools do need a server, mainly the PDF ones. Those files are used for that one job and deleted straight after. We keep no backup and no copy for training or anything else.
Are the calculators and converters accurate?
The unit converters use the exact official values, not rounded ones. An inch is exactly 25.4 mm here and a pound is exactly 0.45359237 kg, and that precision runs through the whole sum instead of being lost in the first step.
More useful than our word for it: every calculator prints the formula it used and the values it put in. You can check the answer yourself. If one of them ever disagrees with your broker, your textbook or your own working, tell us. That is how several tools got fixed, and how a few of them got built in the first place.
How does a free site pay for itself?
Small ads, and the odd coffee from someone a tool helped. That is the whole business model, and we would rather say it plainly than let you wonder what the catch is.
What we do not do: sell data, collect leads, build advertising profiles from your work, or add you to a newsletter you never asked for. There is no account here, so there is nothing to profile in the first place.
Who makes these tools?
A small team that got tired of the same problem you did. We build one tool at a time, use them ourselves, and fix them when somebody points out a wrong number.
Requests come through the contact page and go straight into the queue. Ideas that turn up more than once move to the front. A real person reads every message.
Can I use the results for work?
Yes, at home or at work, free either way. Whatever you make here is yours: QR codes, barcodes, passwords, converted figures, PDFs. We add no watermark, claim no ownership and ask for no credit.
One honest limit. The forex and crypto calculators are maths, not advice. They tell you what your own numbers mean, never what to trade. Check every figure with your broker before you act on it.
Privacy comes first
Not a line in the footer. If a job can be done in your browser, we do it there. Then there is no server copy to promise to delete.
Speed over everything
No upload bar, no queue, no credits, no fake loading screen. You should get your answer before you think about waiting.
No tricks
No forced sign up, no watermark you pay to remove, no free tier that quits on page three of your PDF.
Same tool for everyone
A student, a shopkeeper, a freelancer and a developer all get the full thing. There is no better version behind a paywall.
