Features

What it does

A cross-platform desktop audio format converter built with Electron. AkiConvert decrypts proprietary music formats — .ncm (NetEase), .kwm/.kgm (Kuwo/Kugou), .qmc (QQ Music) and .kgg (Kugou V5) — and converts to and from MP3, FLAC, WAV, OGG, M4A, AAC, AIFF, ALAC and Opus. All decryption and conversion runs entirely offline on your local machine; FFmpeg ships inside the installer, so there is nothing to configure.

🔓

Proprietary format decryption

Decrypts .ncm (NetEase), .kwm/.kgm (Kuwo/Kugou), .qmc (QQ Music) and .kgg (Kugou V5) automatically during conversion. QMCv2 ekey and KGG key databases can be imported for key-protected files.

🎚️

Nine output formats

Convert to MP3, FLAC, WAV, OGG, M4A, AAC, AIFF, ALAC and Opus, with saveable conversion presets for format, bitrate and sample rate.

📦

Batch processing

Queue hundreds of files with configurable concurrency — auto or manual 1–10 — and real-time progress bars.

🏷️

Metadata preservation

Automatically writes title, artist, album, cover art, track number, genre and year as ID3v2 tags.

📊

EBU R128 loudness normalization

Targets −23 to −6 LUFS, with presets matched to streaming platform loudness targets.

🎧

Audio preview player

Built-in player with play queue, previous/next, volume control, seek and lyrics display.

🧩

Naming templates & lyrics

Flexible file names from {title}, {artist}, {album}, {track} and {year} variables; extracts embedded lyrics and embeds companion .lrc files during conversion.

🛡️

Fully offline by design

All decryption and conversion happens locally — your files never leave your machine. FFmpeg is bundled in the installer; conversion history and settings sync come standard.
