MP4 to AVI Converter

Convert video on your device. Codec support affects compatibility; choose quality, bitrate and audio after selecting a file. Re-encoding may change quality and large files need time and memory. A requested file size is not guaranteed.

Files, text, edits and results are processed on your device and kept only in the open page. They are not uploaded for processing. Reloading or closing the page clears the workspace. Files you download to your device remain there until you delete them.

Convert MP4 to AVI when you need compatibility with older tools, legacy editors, or systems that still expect AVI.

AVI is an older container that many enterprise and legacy environments still recognize. If you want a modern, smaller web format, use MP4 to WebM. If you already have AVI and want universal playback, use AVI to MP4.

Best for

• Legacy apps and older video workflows
• Enterprise systems with AVI-only acceptance
• Quick conversions without installing desktop software

Conversion is fully local in your browser using FFmpeg WebAssembly.
