Fast, secure APE to OPUS conversion. No registration required.
APE is the Monkey's Audio lossless codec, trading compression ratio for CPU cost. Reaching a OPUS from there is one hop. A APE to OPUS transcode is mostly about compatibility, not fidelity. At sensible default bitrates you cannot tell the two apart by ear; what you get is a file that actually opens on the hardware or website you were aiming at. FFmpeg handles the heavy lifting and we stream the result straight back as a download. A quick refresher — APE is the Monkey's Audio lossless codec, trading compression ratio for CPU cost. By contrast, Opus is the modern low-latency royalty-free codec used in VoIP, streaming, and WebRTC.
Monkey's Audio
Source formatAPE (Monkey's Audio) is a lossless audio compression format with high compression ratio.
Opus Audio
Target formatOpus is a versatile, open-source audio codec optimized for both speech and music at very low bitrates. It is the standard for WebRTC voice calls and excels at real-time communication.
Why convert APE to OPUS
Moving from APE to OPUS usually buys compatibility or a friendlier file size. For spoken-word content the difference is inaudible; for high-resolution music pick the highest bitrate the OPUS codec supports to avoid compounding compression.
HOW TO CONVERT
APE → OPUS
Provide the audio file
Drag the APE onto the uploader. Files up to 25 MB run on the free tier without registration; paid plans go up to 2 GB.
ffmpeg handles the conversion
Our ffmpeg-based pipeline reads sample rate and channel layout, then writes a matching OPUS with ID3 tags intact.
Save the output
Click to download the OPUS. Batch uploads are bundled into a ZIP for single-click retrieval.
Common Use Cases
Share across platforms
Send OPUS files to anyone without worrying about whether they have the right software for APE.
Embed in documents
Drop OPUS output into Word, Google Docs, PowerPoint, Notion or a website without conversion warnings.
Optimize size
OPUS often produces smaller files than APE for web, email and storage.
Archive & future-proof
Store in a widely-supported format that will still open on future operating systems without legacy plugins.
APE vs OPUS — Strengths and limitations
What each format does best, and where it falls short.
APE Strengths
- Highest lossless compression ratio among mainstream codecs.
- Lossless — bit-exact with the source.
- Active development since 2000.
- APEv2 metadata tags support rich cataloging.
Limitations
- Windows-centric tooling; macOS/Linux support via libmac is second-class.
- Slow encoding at high levels (30-60× realtime).
- Restrictive license blocked adoption by streaming services.
OPUS Strengths
- Best-in-class quality across the entire bitrate range.
- Royalty-free and patent-free.
- Ultra-low latency — suitable for live voice and music.
- Handles speech and music equally well — no need to switch codecs.
- Mandatory codec in WebRTC, so supported in every browser by design.
Limitations
- Very low hardware decoder adoption — software-only on most phones.
- Older platforms (legacy Windows apps, old cars) may not play .opus files.
- Container semantics confusing — Opus lives inside Ogg, WebM, or MP4.

APE vs OPUS — Typical file sizes
Approximate file sizes for common scenarios.
APE
- 3-min song (Normal) 18-25 MB
- 3-min song (Insane) 16-22 MB
- Full CD album 220-350 MB
OPUS
- Voice call (24 kbps) 180 KB/min
- Podcast (48 kbps) 21 MB/hour
- Music (128 kbps) ~1 MB/min
- High-fidelity music (160 kbps) ~1.2 MB/min
Quality & Compatibility
Sample rate, channel layout and bit depth are preserved by default: a 44.1 kHz stereo APE becomes a 44.1 kHz stereo OPUS. Metadata — title, artist, album, cover art — travels where both formats support it. Protected DRM content cannot be converted legally and is rejected.
Tips for Best Results
- Check the podcast host specification before choosing bitrate — some mandate CBR 64 kbps, others accept VBR up to 192 kbps.
- Preserve ID3 tags by editing them before conversion; Mp3tag and MusicBrainz Picard handle round-tripping cleanly.
- If the APE is 24-bit studio audio, the OPUS at 16-bit is sufficient for listening; higher is wasted on consumer playback gear.
Frequently Asked Questions
Lossy-to-lossy conversions (most combinations) re-compress the audio, which technically introduces some loss. At a 192 kbps or higher target it is inaudible on normal equipment. Lossy-to-lossless conversions freeze the existing quality but cannot improve it; lossless-to-lossy transcodes are only as good as the target bitrate you choose.
For voice content (podcasts, audiobooks, lectures) 128 kbps is indistinguishable from higher bitrates. For music, 192-256 kbps covers most listening; 320 kbps is the ceiling for OPUS and the right choice for audio you plan to edit further. Above that, prefer a lossless target instead.
Yes. Title, artist, album, year and cover art travel from the APE container to the OPUS container automatically where both formats support them. If a tag field has no OPUS equivalent, it is dropped silently. Use any tag editor (Mp3tag, MusicBrainz Picard) to fine-tune afterwards.
