Converting to FLAC won't restore lost quality
Your AVI file has already undergone lossy compression. Converting to FLAC preserves what's left — it prevents further degradation from re-saving — but it will not magically sharpen a blurry image or recover discarded audio frequencies.
Some metadata may not survive
Your AVI file may contain RIFF chunks metadata. FLAC has limited or no support for these metadata types. Location data (GPS), camera settings, and color profiles may be stripped during conversion.
About AVI to FLAC Conversion
Short answer: yes, you can convert AVI to FLAC online for free, and quality is well preserved with the right settings. Just upload your .avi file to CocoConvert, pick FLAC as the output, and click Convert. The whole process takes seconds.
Now for the details. AVI (Audio Video Interleave) is Microsoft's legacy video container, widely compatible but often large. FLAC is lossless audio compression — bit-for-bit identical to the original at roughly 50-70% of WAV size. Converting between these two formats lets you preserve files for long-term archival.
Full Name: AVI uses Audio Video Interleave, while FLAC uses Free Lossless Audio Codec. Compression: AVI uses Lossy, while FLAC uses Lossless. Color Depth: AVI uses 8-bit, while FLAC uses —.
Your AVI file is decoded and re-encoded as FLAC. Converting AVI to FLAC maintains high quality with CocoConvert's optimised encoder settings.
Common misconception: ""Converting AVI to FLAC will improve the quality"" — in reality, no. avi has already permanently discarded data during compression. converting to flac preserves what's left but cannot restore lost detail. the file will just be larger.
CocoConvert runs entirely online — no software to install, no account to create. Your files are encrypted during upload (TLS), processed on isolated servers in Germany, and permanently deleted after 24 hours. It works in Chrome, Safari, Firefox, Edge, and all mobile browsers.
Need to convert more than one file? Free users can do 5 per hour. Pro gets 100 per hour with files up to 5 GB each.

What Happens When You Convert AVI to FLAC
The audio track is extracted from your AVI video file and saved as FLAC. The video frames are discarded.
Your AVI file is opened and the container is parsed to identify audio and video streams
The audio stream is extracted — if it's already in the target codec, it's copied directly (no quality loss)
If transcoding is needed, the audio is decoded and re-encoded as FLAC
Video frames, subtitles, and chapter markers are discarded
The FLAC file is saved with preserved metadata (title, artist, etc.) where possible
