Install & first steps

Mojifix is a small Mac app that detects the encoding behind garbled filenames and restores the original names. This page gets you from install to your first repair.

Install

Get Mojifix from the Mac App Store. It is a one-time purchase ($4.99) — no subscription, no in-app purchases. Updates arrive through the App Store like any other app.

Mojifix runs on both Apple-silicon and Intel Macs.

First launch

Opening Mojifix shows a single drop window. There is no account, no setup wizard and no network access — the app works entirely on your Mac, offline.

The interface follows your system language; you can switch it manually from the language selector (English, 日本語, 한국어, 简体中文, 繁體中文).

The three repair tools

Batch-fix files & folders — rename already-extracted files with broken names back to the originals.
Repair a ZIP archive — fix the archive itself before extracting, so names come out right.
Watch a folder — fix newly arriving files automatically, e.g. in Downloads.

All three share the same engine: it inspects the damaged bytes, detects which encoding produced them (Shift-JIS, EUC-KR, GBK, Big5, or macOS NFD normalization), and reverses the damage.
