What is an APE file?
Updated Jul 2026
APE is the file extension for Monkey's Audio, a lossless audio compression format. It shrinks a CD-quality track without losing any sound data, to roughly half the size of the original WAV. But almost no phone, car stereo, or streaming app plays it natively, so people convert it to FLAC or MP3 to actually listen to it.

Why APE exists
Monkey's Audio showed up in the early 2000s, built by a hobbyist developer for people who wanted to rip CDs without throwing away any audio quality. It became popular in audiophile and music archiving circles, where a bit-perfect copy of an album matters more than a small file.
The format works like a very thorough zip file for sound: it packs the waveform down using patterns in the audio itself, then can rebuild the exact original bit for bit. That's different from MP3, which permanently discards details it decides you won't miss. The tradeoff is effort. Monkey's Audio squeezes tighter than most lossless formats, which makes files smaller, but decoding it takes more processing power, so playback can lag on older or low-power devices.
Most people meet an APE file after ripping their own CD collection or receiving a lossless album someone else ripped and shared. It plays fine on a computer with the right software, then refuses to open on a phone, a car stereo, or a smart speaker, which is when converting to FLAC or MP3 becomes necessary.
The trade-offs
Strengths
- Fully lossless, so no audio detail is thrown away
- Compresses tighter than FLAC, meaning smaller files at the same quality
- Well suited to long-term archiving of ripped CDs
- Keeps full dynamic range for critical listening
Watch-outs
- Not supported natively by iPhones, most Android phones, or car stereos
- Slower to decode than FLAC, which can strain older hardware
- Still far larger than MP3 or AAC files
- Less common today, so fewer players and taggers handle it well
A note on privacy
An APE file doesn't carry GPS data the way a photo does, but it can still hold embedded tags, album art, and other details pulled from your music library. Uploading a batch of them to an online converter sends your whole collection's metadata to someone else's server. Converting on your own machine keeps your library, and what it reveals about your listening habits, on your computer.
Questions
How do I open an APE file?
Some desktop media players support it directly, but most phones, car stereos, and streaming apps don't. The reliable fix is converting it to FLAC or MP3 first.
Is APE better than FLAC?
APE usually compresses a bit tighter, so files are smaller for the same lossless quality. FLAC wins on compatibility and playback speed, which is why it's the more common choice today.
Why do I have APE files on my computer?
Usually from ripping a CD collection losslessly or from downloading an album that someone else ripped and shared in this format.
Does converting APE to MP3 lose quality?
Yes, since MP3 is a lossy format and APE is lossless. At a reasonable bitrate the loss is rarely noticeable, but it is permanent once converted.
Can I convert APE without uploading it?
Yes. A desktop app like Morphjet converts APE files on your own computer, so your music and its tags never leave your machine.
Morphjet opens and converts APE and 1,800+ other formats, all on your own computer. Launching this July.
