Free online OPUS to APE converter

Source format: Opus

Opus is a modern, highly efficient audio codec designed for speech and music alike. It is widely used in VoIP, web audio, streaming, gaming voice chat, and messaging apps because it delivers very good quality at low bitrates and handles both low-latency speech and full-band music well. Opus files are commonly stored in an Ogg container with the .opus extension, though the codec itself can also appear in other containers.

Target format: APE

APE usually refers to Monkey’s Audio, a lossless audio format that compresses audio without discarding data. Its main advantage is that it preserves the original waveform exactly, which makes it useful for archiving and bit-perfect storage. APE files are typically larger than lossy formats, and support can be more limited than for FLAC or WAV, especially on portable devices and in web players.

How to perform the conversion

Because Opus is lossy and APE is lossless, converting from Opus to APE does not restore lost audio data; it only wraps the already-compressed audio into a lossless container/codec after decoding. The result will be an APE file, but it will not sound better than the original Opus source.

The most reliable desktop workflow is to use FFmpeg or an audio editor/converter that supports both formats.

1. Install FFmpeg on your computer.
2. Open a terminal or command prompt in the folder containing the Opus file.
3. Run a command such as ffmpeg -i input.opus -c:a ape output.ape.
4. Wait for the conversion to finish, then test the resulting output.ape in a player that supports Monkey’s Audio.

If you prefer a graphical application, use a converter such as Foobar2000 with the appropriate components, or another audio tool that can decode Opus and encode APE. In such software, the usual workflow is File → Open to load the Opus file, then Convert or Save as and choose APE/Monkey’s Audio as the output format.

You can also convert the file on 101convert.com for free, without installing any software.

Notes on quality, compatibility, and limitations

Quality: Since Opus is already lossy, the conversion cannot improve fidelity. If your goal is archival quality, it is better to convert from the original source to a lossless format such as FLAC or WAV, not from Opus.

Compatibility: APE support is less universal than FLAC. Some media players, mobile apps, and hardware devices may not play APE files without extra codecs or plugins.

File size: APE is lossless, so the output is often much larger than the original Opus file.

Metadata: Tags such as artist, album, and track number may not always transfer perfectly between tools, so verify metadata after conversion.

Practical tip: If you only need broad playback compatibility, consider converting Opus to FLAC or WAV instead of APE.
