WHY CONVERT
Why convert MPC to WEBA
02
Acceptance by downstream tools
WEBA 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 MPC reaches an unprepared pipeline.
03
Portable, predictable file format
WEBA is well documented and decodable by long-lived tooling, which matters for archives, deliverables, and any file that needs to outlive the software that created it.

— FAQ
Frequently asked.
Is MPC to WEBA conversion free?
Yes. LocalConvert is completely free, with no signup and no per-file or per-day limits.
Do my files get uploaded anywhere?
No. MPC to WEBA conversion happens entirely inside your browser using WebAssembly — your file never leaves your device.
What's the maximum file size?
There's no fixed cap — the practical limit is your device's available memory. Very large files may take longer or fail on low-RAM devices.
Does it work offline?
Yes — once the page has loaded, MPC to WEBA conversion works without an internet connection. Re-open the page once to cache it.
Will conversion preserve quality?
LocalConvert uses the industry-standard tools (FFmpeg, ImageMagick, Pandoc) — quality matches what professionals use on the command line. Lossy formats will still lose some quality on each re-encode.
