Generation loss — quality may degrade
FLV uses lossy compression, and so does AAC. Converting means decoding and re-encoding — each cycle can permanently degrade quality. Convert from the original source file whenever possible.
Some metadata may not survive
Your FLV file may contain FLV metadata metadata. AAC has limited or no support for these metadata types. Location data (GPS), camera settings, and color profiles may be stripped during conversion.
What compression artifacts to expect
AAC lossy compression can produce pre-echo at low bitrates. At the high quality settings CocoConvert uses by default, these are usually invisible to the eye. Lower quality settings trade visual fidelity for smaller file sizes.

Here's a typical scenario: you receive a .flv file but your project, platform, or client requires .aac. AAC (Advanced Audio Coding) offers better quality than MP3 at the same bitrate — the default codec for Apple devices. Rather than searching for desktop software or wrestling with command-line tools, you can convert FLV to AAC online in seconds with CocoConvert.

What Happens When You Convert FLV to AAC
The audio track is extracted from your FLV video file and saved as AAC. The video frames are discarded.
Your FLV 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 AAC
Video frames, subtitles, and chapter markers are discarded
The AAC file is saved with preserved metadata (title, artist, etc.) where possible
