Remember burning DVDs? Yeah, that's when AVI ruled. But it's 2025, and those 4GB AVI files from your old camcorder are just wasting space. This AVI to MP4 converter brings your videos into the modern era — same quality, 70% less space, actually plays on your phone.
I converted my entire DVD collection last month. 500GB of AVI files became 150GB of MP4s. Same videos, same quality, but now they actually work on my TV, phone, and tablet. No more "codec not supported" errors. No more keeping VLC player just for old files.
