Turn your MP4 videos into AVI, right in your browser — no upload, no signup.
MP4 to AVI Converter turns your .mp4 file into the older AVI container that some legacy software, DVD-authoring tools and older Windows programs still expect. It's a niche need these days — most modern apps prefer MP4 — but when an older program insists on AVI, this gets you there without hunting for an old desktop converter. Add your MP4 files, click convert, and download an .avi that opens where you need it — everything happens right here in your browser, so your footage is never sent to a server.
Drag and drop your .mp4 files, or click to browse. You can add several at once.
Click Convert — this pair usually just repackages the file, so it's typically done in seconds.
Save each .avi file individually, or download every converted file at once as a .zip.
Your videos are processed locally and never leave your device.
Works straight in your browser — no software, no account, no email.
MP4 and AVI are close enough that this conversion is normally a quick repackage, not a re-encode.
Convert as many videos as you like, with no limits or hidden fees.
