MENGAPA MENGONVERSI
Why convert WEBM to MP4
02
Broader cross-platform support
MP4 is accepted by a wider range of video players, mobile devices, and streaming platforms than WEBM. The conversion removes a recurring compatibility friction without changing what the file actually contains.
03
Lower storage and bandwidth cost
MP4 files are typically smaller than their WEBM 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 WEBM ke MP4 gratis?
Ya. LocalConvert sepenuhnya gratis, tanpa pendaftaran dan tanpa batas per file atau per hari.
Apakah file saya diunggah ke suatu tempat?
Tidak. Konversi WEBM ke MP4 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 WEBM ke MP4 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.
