Technical Details

Our AVI to MP4 converter uses FFmpeg, a powerful multimedia framework, to transcode your videos. The conversion process:

  1. Decodes the AVI video using appropriate codecs (typically DivX, XviD, or other codecs used in AVI)
  2. Processes the video and audio streams
  3. Encodes the video using the H.264 codec and the audio using AAC
  4. Packages everything into the MP4 container format
  5. Preserves metadata when possible

Frequently Asked Questions

Will I lose quality when converting from AVI to MP4?

When converting between video formats, some quality loss is possible. However, our converter uses high-quality settings to minimize this loss. In most cases, the difference is imperceptible to the average viewer, and the H.264 codec used in MP4 is actually capable of better quality than many codecs used in AVI files.

Can I convert old AVI files from my camcorder?

Yes! Our converter works with AVI files from any source, including those created by older camcorders, digital cameras, or screen recording software.

Is my data secure?

Yes! All processing happens locally in your browser. Your files are never uploaded to our servers, ensuring complete privacy and security.

Can I convert multiple files at once?

Currently, our tool processes one file at a time. For batch conversion, you'll need to convert each file individually.

What MP4 quality settings are used?

We use high-quality settings that balance excellent video quality with reasonable file size. By default, we use the H.264 codec for video and AAC for audio, which provide excellent compatibility and quality.

Can I use this on my mobile device?

Yes, our converter works on modern mobile browsers, though the experience may be optimized for desktop use.
