Free online AVI→MP4 converter. Fast, private, no sign-up.
Going from AVI to MP4 takes a couple of clicks: drop the file in, download the result. Drop in your AVI file (a .avi) and download a ready-to-use MP4 file (a .mp4) — no software to install, no account to create, and no watermark on the output.
AVI is a long-lived Microsoft container — widely readable, but its older codecs are far less efficient than modern formats, so files tend to be large.
MP4 (H.264) is the most compatible video format in the world — it plays on virtually every device, browser and social platform.
You'll reach for a AVI to MP4 conversion whenever the other end expects MP4 specifically — uploading somewhere, importing into software, or sharing with someone whose device prefers it. The conversion runs through ffmpeg, the industry-standard media engine, re-encoding the streams with sensible high-quality defaults so the result plays cleanly on your target device.
Typical uses: preparing assets for a website, attaching a file someone else can definitely open, or standardising a folder of mixed files into one format.
Privacy is the default here. Your AVI file is uploaded over an encrypted connection, converted, downloaded the moment it's ready, and then deleted automatically a short time afterwards. We never keep your files, never build a library of your content, and never make you sign up to download the result.
