AVI is an aging container with inefficient codecs, which is why AVI files are so large for their quality. This tool runs a full FFmpeg build compiled to WebAssembly inside your browser: it decodes your AVI, re-encodes the stream as modern H.264 MP4, and hands you a much smaller file — without uploading anything to a server. Old camcorder clips and archive footage finally fit into email and chat limits.

Vanlige spørsmål

Why is AVI converted to MP4?

AVI usually wraps old codecs like DivX/Xvid that are inefficient and poorly supported. Re-encoding to H.264 MP4 typically cuts size by 50–80% while improving compatibility with phones, browsers and chat apps.

Does the file get uploaded anywhere?

Nei. Selve FFmpeg-motoren lastes ned én gang fra et CDN og bufres av nettleseren din; videofilene dine behandles utelukkende i lokalt minne.

Hvorfor er den første komprimeringen tregere?

Den første kjøringen henter ~31MB WebAssembly-motoren. Etterpå bufres den og hver komprimering starter umiddelbart.

Hvor store kan inndatafiler være?

Opptil ca. 200MB avhengig av minnet på enheten din, siden alt kjører i nettleseren. For større filer, del dem først eller bruk 500MB-mål MP4-verktøyene på en allerede konvertert kopi.
