Free online MP4→AVI converter. Fast, private, no sign-up.
Converting MP4 to AVI is one of those small tasks that should be instant and free — and here it is. Drop in your MP4 file (a .mp4) and download a ready-to-use AVI file (a .avi) — no software to install, no account to create, and no watermark on the output.
MP4 (H.264) is the most compatible video format in the world — it plays on virtually every device, browser and social platform.
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.
You'll reach for a MP4 to AVI conversion whenever the other end expects AVI 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.
You might be optimising images for a faster-loading page, exporting for a specific app or marketplace, or just making sure a colleague on a different device can open what you send.
Privacy is the default here. Your MP4 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.
