About DocMoa

What DocMoa is

DocMoa is a free collection of document tools that run in your web browser: 59 tools for PDF, Word, HWP, Markdown, images, CAD drawings and QR codes, available in 20 languages. It launched in September 2026 and is maintained continuously; new tools and fixes ship every week.

How it works

Most tools do their work on your own device with JavaScript and WebAssembly. Your files are never uploaded, so there is nothing for us to store, read or lose. The two exceptions, the AI conversion tool and the Korean address converter, state before use exactly what leaves your browser and where it goes.

Who runs it

DocMoa is independently built and operated from South Korea by the developer behind it. Every tool is written and tested by hand, and the text on each tool page describes what that tool actually does, including its limits.

How it is funded

The site is free and requires no account. It is paid for by Google AdSense advertising on tool pages. This page, the privacy policy and the terms of service carry no ads.
