About AVI
AVI (Audio Video Interleave) is a container format Microsoft introduced in 1992 for video on Windows.
Older cameras, Windows software and video collections from the 1990s and 2000s.
AVI predates modern codecs and has no native support for features such as variable frame rate, so it is rarely used for new video.

Why is my AVI file so much bigger than modern video? The container predates efficient codecs like H.264, so an hour of video can take many gigabytes that an MP4 would store in a fraction of the space.
About FLAC
FLAC (Free Lossless Audio Codec) compresses audio without losing anything: the files are typically half to two thirds the size of WAV and decode back to the exact original samples.
Music archives, CD rips and high-resolution downloads.
FLAC files are several times larger than MP3, and some older players and car stereos do not play them.
Why convert CDs to FLAC instead of MP3? The copy is bit-for-bit identical to the original, so the archive never loses quality however often it is converted later.
What changes when you convert AVI to FLAC
- The soundtrack of the AVI is re-encoded as FLAC at the default settings, so it is close to the original but not bit-identical.
- Only the sound is kept: the FLAC file contains the audio track of your AVI, and the picture is dropped.
Settings you can change
Before you convert AVI to FLAC, you can adjust: Audio codec, Rate control, Audio bitrate, Quality (VBR), Sample rate, Channels, Normalize loudness, Trim start, Trim duration, and Keep tags.
Limits
Each plan sets a maximum file size and a number of conversions per day, and video and audio files also have a maximum length. Guests can convert files up to 100 megabytes and 5 per day; a free account raises this to 500 megabytes and 25 per day; paid plans go up to 100 gigabytes.
Your converted FLAC file is kept for 2 hours, then deleted.
