info À propos de cet outil
Modernisez votre librairie AVI en compressant vos vidéos en MP4 (H.264/AAC). Poids plus faible.

File size: MP4 output is typically 20–50% smaller than AVI. Uncompressed or MJPEG AVI files shrink much more dramatically.

Quality: Re-encoding from AVI to H.264 involves one generation of quality loss. Results are excellent for viewing but not lossless. Retain original AVI files for archiving.

help FAQ

My AVI uses DivX or Xvid codec — will it convert?

Yes. Our converter handles the most common AVI codecs including DivX, Xvid, MJPEG, and uncompressed AVI.

Will the video quality be maintained?

We transcode at high quality settings. Some quality loss from re-encoding is expected — this is unavoidable when changing codecs. The result is visually excellent for standard viewing.

How much smaller will the MP4 be?

AVI files using older codecs (Xvid, DivX) convert to MP4 at 20–40% smaller size. Uncompressed AVI files can shrink by 90%+ when converted to H.264.

Can I upload the resulting MP4 to YouTube?

Yes. MP4 with H.264/AAC is YouTube's recommended upload format and produces the fastest processing times.
