Turn your AVI videos into MP4, right in your browser — no upload, no signup.
AVI to MP4 Converter modernizes an old .avi file into MP4, the format today's phones, streaming services and social platforms actually expect. AVI was common years ago but a lot of modern apps and devices no longer play it well, or at all — this brings an old recording or archived clip back to something you can share, upload or watch anywhere. Add your AVI files, click convert, and download an .mp4 that plays everywhere — everything happens right here in your browser, so your footage is never sent to a server.
Drag and drop your .avi 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 .mp4 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 is the one format that's safe to assume any phone, app or editor will open.
Convert as many videos as you like, with no limits or hidden fees.
