How do I convert WMA audio to Opus without losing quality?

Upload the WMA file and the converter chooses the Opus codec / bitrate combination that matches the source profile. Lossless Opus (WAV / FLAC / ALAC) preserves every sample exactly; lossy Opus (MP3 / AAC / OGG / Opus) defaults to 192 kbps which is transparent for almost all music content.

What bitrate does the Opus file end up at?

Default 192 kbps for lossy Opus; pass-through for lossless Opus. Override to 320 kbps if you want maximum lossy fidelity, 128 kbps for size-constrained podcast distribution, or 96 kbps for voice-only sources where the smaller file matters more than studio detail.

Will going from WMA to Opus actually reduce my audio quality?

If WMA is lossy (MP3, AAC) and Opus is lossless (WAV, FLAC), the Opus is no better than the WMA — you cannot recover information already discarded by the lossy WMA codec. If WMA is lossless and Opus is lossy, expect the Opus encoder to recompress; at 192 kbps the loss is imperceptible to most ears.

Does the WMA to Opus converter keep ID3 / metadata tags?

Yes — title, artist, album, year, track number, album art, BPM, replay-gain are read from the WMA container and written into the equivalent fields on the Opus container. ID3v2 (MP3), Vorbis comments (OGG, FLAC), MP4 atoms (AAC, M4A), RIFF INFO (WAV), iXML chunks all map cleanly.

Can I batch-convert hundreds of WMA files into Opus?

Yes — drop a folder of WMA files in and we process them in parallel. Premium has more parallel workers and no per-file size cap, so a 500-file batch finishes in minutes rather than tens of minutes. Folder structure is preserved in the output ZIP.

Will the Opus keep the same sample rate as the WMA?

By default yes (a 48 kHz WMA produces 48 kHz Opus, a 44.1 kHz WMA produces 44.1 kHz Opus). For specific compatibility — e.g. downsampling 96 kHz studio masters to 44.1 kHz Opus for CD burning, or upsampling 22 kHz voicemail to 44.1 kHz Opus — the sample-rate dropdown applies high-quality SOX-style resampling.

Can I normalize loudness in the WMA to Opus step?

Yes — the loudness-normalize option applies ITU-R BS.1770 / EBU R128 normalization to the Opus output, targeting -14 LUFS (streaming standard) or -16 LUFS (podcast standard) or a custom value. Useful when batch-converting tracks with varying mastering levels into a single Opus playlist.

Will the Opus play on my car stereo / iPod / Sonos / Bluetooth speaker?

MP3 plays universally on every device made in the last 20 years. AAC plays on Apple, most Android, Sonos, and modern car stereos. FLAC plays on Sonos and recent Android, less well on older iPods. WAV plays on everything but the file is huge. The device-target dropdown picks a safe Opus codec for the platform you specify.

Is my WMA file private during conversion?

Yes — uploaded WMA files are processed in isolated workers and deleted within minutes. We never play, store, or share the audio content. The pipeline runs on hardware we control end-to-end; no third-party services receive your file.

How long does converting a 1-hour WMA to Opus take?

Same-codec re-mux (e.g. AAC inside M4A -> AAC inside MP4): 10-30 seconds. Codec change (e.g. FLAC -> MP3 or WAV -> AAC): typically 10-20% of source duration, so a 1-hour WMA -> Opus finishes in 6-12 minutes on the standard pipeline.

Why is the Opus file louder or quieter than the WMA source?

No automatic gain change happens unless the normalize option is turned on. If you do hear a level shift, your audio player or media library may be applying ReplayGain or per-track normalization on playback — turn that off and the Opus sounds bit-identical to the WMA (for lossless) or perceptually identical (for transparent lossy).

Can I convert WMA downloads from Bandcamp / SoundCloud into Opus?

If the WMA download is unprotected (no DRM), yes. DRM-encrypted streaming files (Spotify offline, Apple Music) are encrypted at the bit level and cannot be processed. Sources from Bandcamp purchases, SoundCloud go downloads, podcast feeds, and personal recordings all convert cleanly into Opus.
