AVI

AVI (Audio Video Interleave) is one of the oldest and most recognized multimedia container formats, introduced by Microsoft in November 1992 as part of its Video for Windows technology. Built on the Resource Interchange File Format (RIFF) structure, AVI interleaves audio and video data in alternating chunks, allowing synchronized playback without requiring sophisticated stream management. The format is codec-agnostic, meaning it can hold video compressed with virtually any codec, from early Cinepak and Indeo to modern DivX, Xvid, and H.264 streams. This flexibility contributed to widespread adoption across personal computers throughout the 1990s and 2000s. AVI supports multiple audio streams, enabling multilingual content within a single file. Despite being decades old, AVI remains one of the most universally recognized multimedia formats and is still widely supported by media players and editing tools across all major operating systems.

Frequently Asked Questions

Is converting WMV to AVI free?

Yes. This WMV → AVI converter runs entirely in your browser and is completely free — no account, no credits, no watermark.

Which devices and platforms can I use to convert WMV to AVI?

Any modern device with a current web browser: Windows, macOS, Linux, Android, iPhone and iPad. There is nothing to install — the conversion happens locally.

Are my WMV files uploaded to a server?

No. Files never leave your device. The entire WMV → AVI conversion runs locally in your browser, so your data stays private.

Can I convert multiple WMV files at once?

Yes — batch conversion is supported. Add as many WMV files as you like and convert them to AVI in one pass, then download the results together.

What is the maximum file size?

There is no fixed server-side limit because the conversion happens in your browser. Practical limits depend on the available memory and CPU of your device.

Will converting WMV to AVI reduce the quality?

Because both formats use lossy compression, the AVI output will not bring back any quality that has already been lost in your WMV file. Avoid repeated re-encoding to keep the best quality.

Does AVI support transparency?

No — AVI has no alpha channel. Transparent areas of your WMV file will be filled with a solid background colour in the converted file.

How will the file size change after converting WMV to AVI?

Both formats use comparable compression, so the AVI output will be similar in size to your WMV file — typically within 10–20% of each other.
