details

MP3 to OGG on your pc

Convert mp3 to ogg on Windows with a local utility built for quick, simple audio conversion.

how it works

This mp3 to ogg converter uses ffmpeg.wasm and runs on your Windows device. Your audio files are processed locally, and the OGG audio file is created without uploading anything.

paste from clipboard

Press Ctrl+V to drop a copied audio file straight into the queue. If you copied an MP3 audio file in File Explorer or another app, it can be added right away.

batch conversion

Convert a whole folder of audio files in one run, including folders with subfolders. The output keeps the same folder structure on the other side.

auto-convert watcher

Open the Auto-convert page, choose a watched folder and an output folder, and let the app keep working in the system tray. Drop a fresh export there and the converted copy appears next to it.

right-click in explorer

A native shell extension adds Convert to OGG to the right-click menu for .mp3 files in File Explorer. It opens the app with your selection already loaded.

languages & themes

The UI is available in ten languages. Light and dark themes follow your Windows theme automatically.

offline by design

No telemetry, no account, and no user data sent to a server. Your audio files stay on your device from start to finish.

free & pro

The free version lets you convert MP3 to OGG with no file size or file count limits. Upgrade to Pro with a one-time lifetime purchase to remove ads and unlock batch conversion. No subscriptions or recurring payments.
