MENGAPA MENGONVERSI
Why convert 3GP to ALAC
02
Acceptance by downstream tools
ALAC 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 3GP reaches an unprepared pipeline.
03
Lower storage and bandwidth cost
ALAC files are typically smaller than their 3GP counterparts, which reduces hosting, transfer, and storage costs at scale. The savings compound when serving the same content to many recipients.

— FAQ
Pertanyaan umum.
Apakah konversi 3GP ke ALAC gratis?
Ya. LocalConvert sepenuhnya gratis, tanpa pendaftaran dan tanpa batas per file atau per hari.
Apakah file saya diunggah ke suatu tempat?
Tidak. Konversi 3GP ke ALAC terjadi sepenuhnya di dalam peramban Anda menggunakan WebAssembly — file Anda tidak pernah meninggalkan perangkat Anda.
Berapa ukuran file maksimum?
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.
Apakah berfungsi secara offline?
Ya — setelah halaman dimuat, konversi 3GP ke ALAC berfungsi tanpa koneksi internet. Buka ulang halaman sekali untuk menyimpannya dalam cache.
Apakah konversi akan mempertahankan kualitas?
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.
