About ToolKraken
ToolKraken is a growing collection of 120+ free online tools — calculators, converters, and generators for students, teachers, creators, and developers. Every one runs instantly in your browser, with no accounts and no installs.
What you can count on
- Always free. Every tool, every feature — no paywalls, no "pro" upsell, no trial.
- No sign-up. Open a tool and use it. We never ask for an email or account.
- Private by design. Tools run locally in your browser. The text, numbers, and files you enter are processed on your device — we don't upload them to a server or store them.
- Fast and clean. Each tool does one job well, loads quickly, and works on your phone or laptop.
Why it's free
Running ToolKraken costs very little because the tools work in your browser instead of on expensive servers. A few unobtrusive ads cover the bills — that's the whole business. No selling data, no hidden subscriptions. Free tools, kept free.
Who it's for
Students checking a GPA or a final-exam score. Teachers grading a stack of papers. Creators sizing a thumbnail or counting caption characters. Developers formatting JSON or decoding a token. If it's a small task you'd rather not download an app for, there's probably a ToolKraken tool for it.
