Common questions
Are the tools really free?
Yes. Every calculator, converter and generator on Toolfix is free to use with no hidden paywalls, trial limits or subscriptions.
Do I need to create an account?
No. You can open and use any tool instantly without registering, giving an email address or installing anything.
Is my data safe?
Browser-based tools such as calculators, word counters and QR generators run locally on your device, so your inputs are not sent to or stored on our servers. A few tools that need to fetch online data (for example a website analyzer) send only the URL you enter.
How accurate are the financial calculators?
Our calculators use standard published formulas and we review fee and rate assumptions regularly. Results are estimates for planning, not financial, legal or tax advice.
Can I use Toolfix on my phone?
Yes. Every tool is built with a responsive layout that works on iOS and Android phones and tablets.
