Convert AVI video files to MP4 format in seconds. Upload your AVI files from old cameras or Windows, wait for processing, and download MP4. No signup required. Ideal for compatibility with phones, smart TVs, and streaming. You can also reverse this action with our Convert MP4 to AVI tool.
An AVI to MP4 converter transforms AVI video into MP4 format. AVI is common from older cameras, dash cams, and Windows recording software. MP4 uses H.264 compression - smaller files, better quality, and universal support on phones, smart TVs, YouTube, and social media.
AVI from dash cams and old cameras often fails on phones and smart TVs. MP4 plays everywhere. Our tool converts AVI to MP4 in the browser - no VLC, no account, and your files are purged after conversion. If you rely on newer video codecs, check out our Convert MP4 to WebM feature.
Many older cameras and dash cams record in AVI. Convert to MP4 before uploading to YouTube, sharing on social media, or playing on phones and smart TVs that struggle with AVI.
OBS, Camtasia, or built-in Windows recorders often output AVI. Convert to MP4 for smaller file size, faster uploads, and compatibility with video platforms and editing software.
Digitize old AVI footage from camcorders or convert archived videos to MP4 for long-term storage. MP4 is the standard for modern playback and cloud backup.
Drag and drop your AVI file onto the upload area or click to browse. You can add multiple files - they will be processed one by one. Supported formats include standard AVI (DivX, Xvid, MJPEG).
The tool uploads your file and queues it for conversion. You will see the status: uploading, queued, or processing. Typical conversion takes under a minute for most clips. Estimated wait time is shown when the queue has multiple jobs.
When conversion finishes, a download button appears. Click it to save the MP4 file to your device. The original filename is preserved with the .mp4 extension. You can convert more files without refreshing the page. iOS users often use our Convert MOV to MP4 tool as well.
MP4 H.264 is efficient - a clean AVI source yields excellent MP4 output. If your AVI is already compressed (DivX, Xvid), expect similar or slightly smaller output. Avoid re-encoding multiple times.
Add several AVI files at once. They process in order. While one converts, you can prepare the next. No need to wait for each file to finish before adding another.
MP4 is the universal format. After converting, use MP4 for uploads, backups, and playback. Keep AVI originals only if you need them for legacy software. For HTML5 video integration, consider to Convert WebM to MP4.
