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

  1. Upload your AVI file: from a computer, phone, or tablet. The free online tool takes files up to 2 GB.
  2. 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.
  3. 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.

FAQ

Is the AVI to MP4 converter free?

Yes. The free plan includes 3 uploads, and each one converts to MP4 with a transcript and AI chat included. Paid plans start at $19 a month billed annually and remove the per-recording limits.

How large an AVI file can I convert?

The free online tool on this page takes files up to 2 GB, which covers most camera recordings, dashcam footage, and archived videos, even long ones. The ScreenApp app has no set file size limit. CloudConvert's free tier caps files at 1 GB; Adobe Express's free video converter caps files at 1 GB.

Do I need to install anything to convert AVI to MP4?

No. Upload the file in your browser and download the MP4 when it is ready. No desktop converter, no plugin.

Does converting to MP4 improve the video quality?

No. The MP4 keeps the source file's resolution and framerate. An AVI recorded at low resolution stays at that resolution after conversion; only the container and codec change.

Does the AVI to MP4 converter work on mobile phones?

Yes. Upload from an iPhone or Android browser the same way you would from a desktop, and download the MP4 when processing finishes.

Can I convert several AVI files to MP4 at once?

Yes. ScreenApp supports bulk upload of multiple files, so you can convert more than one AVI file in the same batch.

Why is AVI still around if it is so old?

AVI dates back to early Windows video and is still produced by some cameras, dashcams, and capture software, but it compresses less efficiently than MP4 and plays on fewer modern apps. Converting old recordings to MP4 once removes that compatibility problem for good.

What do I get besides the converted file?

A transcript of the audio in 100+ languages, with speaker labels, plus AI chat with any recording on the same file. Export the transcript as PDF, DOCX, TXT, SRT and VTT.
