About Limcogito Toolbox

What this site is

Limcogito Toolbox is a collection of small, focused online tools built for everyday tasks: compressing and converting images, working with PDF files, creating QR codes, calculating Vietnamese gross and net salary, counting words, estimating BMI and calories, and converting between solar and lunar dates.

The site is available in Vietnamese and English, and every tool has its own page with a short guide and answers to common questions.

Built to run in your browser

Wherever it is possible, the work happens on your own device. Image and PDF tools read your files locally and never upload them to a server, which keeps your documents private and makes the tools fast even on a slow connection.

Who runs it
