MENGAPA MENGONVERSI

Why convert MP4 to WEBM

01

Modern compression standards

WEBM typically achieves better compression efficiency than MP4 at equivalent perceived quality. The result is a smaller file that still looks or sounds the same to most listeners and viewers.

02

Broader cross-platform support

WEBM is accepted by a wider range of video players, mobile devices, and streaming platforms than MP4. The conversion removes a recurring compatibility friction without changing what the file actually contains.

03

Lower storage and bandwidth cost

WEBM files are typically smaller than their MP4 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 MP4 ke WEBM gratis?

Ya. LocalConvert sepenuhnya gratis, tanpa pendaftaran dan tanpa batas per file atau per hari.

Apakah file saya diunggah ke suatu tempat?

Tidak. Konversi MP4 ke WEBM 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 MP4 ke WEBM 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.
