Convert an AVI File to MP4
AVI to MP4 converter takes an older video file, from a camera, a dashcam, or an archive, and gives it back as an MP4 that plays on modern devices and drops into any editor. Upload the file and download the converted copy, no software or account setup beyond signing in.
What you get:
- An AVI file converted to MP4, original resolution and framerate kept
- Free online tool takes files up to 2 GB
- bulk upload of multiple files, so several AVI files convert in one batch
- A transcript of the audio, with speaker labels, in 100+ languages
- AI chat with any recording, so you can ask the converted video a question instead of watching it back
- Export the transcript as PDF, DOCX, TXT, SRT and VTT
- Free plan: 3 uploads, lifetime, each with the transcript and AI chat included
How to Convert AVI to MP4
- Upload your AVI file: from a computer, phone, or tablet. The free online tool takes files up to 2 GB.
- Let it process: the file converts to MP4 and the audio transcribes at the same time. Both are ready in your library once processing finishes.
- Download the MP4: open the file and download it. The transcript, speaker labels, and AI chat are attached to the same recording.
The MP4 keeps the source file’s resolution and framerate, so a low-resolution camera or dashcam file stays low-resolution: converting the container does not add detail that was never recorded. Transcript quality follows the audio: clear narration transcribes cleanly, and an old recording with wind noise or engine noise will have more gaps. See how we measure accuracy.

Who Converts AVI to MP4
Video archivists and collectors work through old AVI archives, camera footage, and backups. Converting a batch of files to MP4 turns an unplayable archive into something a browser or media player opens without a plugin.
Content creators and editors pull AVI footage into a modern editing project. Many editors prefer MP4, so converting first means the clip drops into Premiere Pro, Final Cut Pro, or DaVinci Resolve without a format error.
Family video preservationists digitize old family videos recorded in AVI. Converting to MP4 keeps the memory playable on a phone, tablet, or smart TV.
Business professionals modernize old training videos, presentations, and corporate archives so legacy content plays on current systems and platforms.
Camera and dashcam users convert AVI recordings from older cameras and dashcams to MP4, making the footage easier to play back and to share by email or on social media.
