Common questions
What kinds of tools are on FreeToolBank?
Tools for writing and editing, developers, business and money, converting files, dates and time, accessibility, engineering, fitness and games. Browse by category above, or open All tools for the full list. Every one is free and runs in your browser, and new tools are added to the category they belong in.
Are the tools really free?
Yes, and permanently. There is no paid tier on any tool, no size cap, no daily limit and no watermark. "Free" is in the name, so gating the tools later would make the name a lie.
Do I need to create an account?
No. There is no account system at all, so there is nothing to sign up for and nothing to log into. Open a tool and use it.
Is my data uploaded to your server?
No. The tools run in your browser using JavaScript on the page, so whatever you paste or open stays on your device. You can verify this: open your browser developer tools, switch to the Network tab, and use any tool. Nothing leaves.
Do the tools work on a phone?
Yes. Every tool is built mobile-first and tested at 360px wide, which is narrower than most phones. Some tools with wide tables scroll sideways inside their own panel rather than making the page scroll.
Can I use them offline?
Mostly. Once a tool page has finished loading, the tool itself keeps working without a connection, because the processing happens locally. You need to be online to load a page in the first place.
How do you make money if everything is free?
Some tools carry a relevant recommendation below the output, and some link to paid services in the same field. None of that gates a tool or changes what it does. If we ever add advertising it will stay light, because heavy advertising is the main complaint about the sites we are trying to beat.
