About FailX

Handy tools with nothing to install, nothing to upload, and nothing to pay.

What FailX is

FailX is a free collection of small online tools for everyday tasks — counting characters, converting units and images, estimating take-home pay, converting HWP documents and more. Everything runs in your browser with nothing to install. There are currently 31 tools, available in Korean and English.

Our principles

Free, no sign-up: every tool works right away. Running costs are covered by advertising.
Your files stay on your device: images, photos, HWP documents and text you enter are processed in your browser, not uploaded to our servers.
Transparent calculations: calculators use official sources — for example the National Tax Service withholding table and the year’s social insurance rates — and each guide explains the method and its limits.
Built for phones too: every tool is designed to work well on small screens.
