Lanren Toolkit is a free collection of online tools — currently 16 of them, spanning finance, everyday utilities, social/classroom helpers, and life & fun tools.
Working out a loan payment, converting a currency, or generating a password shouldn't mean digging through search results full of pop-up ads and forced sign-ups. Our goal is simple: open it and it just works — no install, no signup, no email required. Every tool runs directly in your browser.
Most tools (BMI calculator, password generator, image compressor, etc.) run entirely in your browser — nothing is sent to a server. A few tools that need live data (currency converter, QR code generator) do call an external API; see our Privacy Policy for details.
Ads on the page keep the site running and funded for future development. We've tried to keep them out of the way (side rails, footer) rather than blocking content — thanks for understanding.
Head over to the Feedback page and let us know — new tool ideas, bugs, anything. We read every submission. You can also email us directly at hello@lanrenkit.com.
