How to convert AVI to MP4
Old AVI files from cameras and downloads often won't play on modern phones or browsers. Converting to MP4 brings them up to date and usually makes them smaller.
- Drop your AVI file into the box above, or add it from a link.
- MP4 is already selected. Use the settings button next to it to change size, quality or other options.
- Select Convert, then download your MP4 file.
To do this from your own code, call the FileForge API with "output_format": "mp4".
Good to know
- Modern H.264 compression often makes the file much smaller than the AVI.
- Interlaced footage from old camcorders may show fine lines on fast motion; that's in the source.
About the formats
.avi
AVI is an old Microsoft video format. Files are often large and use dated codecs, so modern phones and browsers frequently can't play them.
.mp4
MP4 is the most widely supported video format. It plays on practically every phone, browser, TV and editor, usually with H.264 video and AAC audio inside.
Questions
Will the MP4 be smaller?
Usually yes, often a lot, because H.264 is more efficient than the codecs typically found in AVI files.
