Frequently Asked Questions

AVI (Audio Video Interleave) is a multimedia container format introduced by Microsoft in 1992. While older, it remains widely supported on Windows systems, DVD players, and legacy devices. Use AVI when you need compatibility with older software, hardware DVD players, or Windows-centric workflows that don't support modern formats.

AVI files work reliably on virtually any Windows computer and many standalone media players without requiring additional codecs. They're simple to edit in older video software and maintain broad hardware support. For archival purposes or legacy systems, AVI's simplicity and universal Windows compatibility can be advantages over newer formats.

AVI works on Windows Media Player, VLC, most DVD players with USB playback, older video editing software (Sony Vegas, Adobe Premiere CS versions), DivX/Xvid-certified devices, and most media centers. It's the safest format for ensuring playback on unknown legacy Windows systems.

AVI files are typically 10-30% larger than MP4 with equivalent quality due to less efficient container overhead. However, this depends on the codec used inside the container. Modern H.264 in AVI approaches MP4 efficiency, but classic codecs like MPEG-4 Part 2 create larger files.

Many standalone DVD players support AVI files with DivX/Xvid codecs when played from USB or burned to disc. This makes AVI useful for creating video discs that play on older hardware. Check your player's supported formats - look for 'DivX Certified' or 'AVI support' in specifications.

For archival or editing, choose 'Best' quality. For DVD player playback, 'High' works well. For file sharing or storage-constrained situations, 'Smaller' or 'Smallest' reduce file size while maintaining watchable quality. Higher quality means larger files and slower processing.

Yes, AVI is well-supported in most video editors including Adobe Premiere, Sony Vegas, Windows Movie Maker, and VirtualDub. Older editing software often prefers AVI over newer formats. For professional work, consider using higher-quality intermediate codecs rather than compressed formats.

No. All conversion happens entirely in your browser using FFmpeg WebAssembly. Your video files never leave your device, making this tool completely private and secure. You can even use it offline after the page loads.

Conversion is always slower than the video's duration - a 1-minute video might take 3-10 minutes. Speed depends entirely on your device: desktop computers convert faster than phones or older laptops. Higher quality settings also increase processing time. For large files or frequent conversions, consider desktop software like HandBrake.

Keep 'Original' to preserve your source resolution for best quality. Choose lower resolutions (720p, 480p) to reduce file size for DVD players or older devices with limited processing power. Lower resolutions also speed up conversion and reduce storage requirements.
