MENGAPA MENGONVERSI
01
Converting from AU to OPUS aligns the file with the encoding choices the downstream pipeline expects. The result is a deliverable that fits naturally into the destination workflow.
02
OPUS is the format most receiving systems expect for this kind of content. Converting upstream avoids the rejection and silent re-encoding that often happen when AU reaches an unprepared pipeline.
03
OPUS files are typically smaller than their AU counterparts, which reduces hosting, transfer, and storage costs at scale. The savings compound when serving the same content to many recipients.

|---|---|---|
| PRIVASI | Files never leave your device. The whole pipeline runs in your browser via WebAssembly. | Files travel to a remote server, sit in queue storage, and may be retained for analytics or moderation. |
| BIAYA | Free, no signup, no daily quotas. | Often free for small files; paid tiers for batch / large / commercial use. |
| BATASAN | Limited only by your device's memory and CPU. Uncompressed WAV stems handled comfortably on desktop. | Typical 100 MB to 1 GB per-file caps, plus rate limits. |
AU is a file format supported by LocalConvert.
A modern low-latency lossy codec excellent for speech and music across all bitrates.

Ya. LocalConvert sepenuhnya gratis, tanpa pendaftaran dan tanpa batas per file atau per hari.
Tidak. Konversi AU ke OPUS terjadi sepenuhnya di dalam peramban Anda menggunakan WebAssembly — file Anda tidak pernah meninggalkan perangkat Anda.
Tidak ada batas tetap — batas praktisnya adalah memori yang tersedia di perangkat Anda. File yang sangat besar mungkin memerlukan waktu lebih lama atau gagal pada perangkat dengan RAM rendah.
Ya — setelah halaman dimuat, konversi AU ke OPUS berfungsi tanpa koneksi internet. Buka ulang halaman sekali untuk menyimpannya dalam cache.
LocalConvert menggunakan alat standar industri (FFmpeg, ImageMagick, Pandoc) — kualitas sesuai dengan yang digunakan profesional di baris perintah. Format lossy (dengan kehilangan) akan tetap kehilangan sedikit kualitas setiap kali dikode ulang.
