Why FreshToolkit?
Private by design. Most online tools upload your files and text to a server. FreshToolkit tools run 100% in your browser, so your photos, documents and numbers stay on your device. You can even disconnect from the internet after a page loads and the tools keep working.
Accurate and transparent. Every calculator shows its formula and a worked example on the page, so you can check the maths instead of trusting a black box. Conversion factors are the exact international definitions.
Fast and free. No accounts, no paywalls, no intrusive popups. Pages are lightweight and work on any phone or computer.
Frequently asked questions
Are these tools really free?
Yes — every tool is free for personal and commercial use, with no limits and no registration. The site is supported by unobtrusive advertising.
Do you store the data I enter?
No. Calculations happen locally in your browser. We do not receive, store or see the numbers, text or files you use in any tool.
Can I use FreshToolkit offline?
Once a tool page has loaded, its calculator or converter keeps working without an internet connection, because everything runs on your device.
