AVI to MP4 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.

AVI to MP4 modernizes legacy video files. AVI often causes compatibility problems on mobile devices and web platforms, while MP4 is widely supported and easy to share.

Use this conversion to make older videos play smoothly on modern devices. For web-first optimization, convert to MP4 first, then consider MP4 to WebM.

Best for

• Fixing compatibility issues with older AVI files
• Uploading to modern platforms that prefer MP4
