Converting to WAV won't restore lost quality
Your FLV file has already undergone lossy compression. Converting to WAV 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 FLV file may contain FLV metadata metadata. WAV has limited or no support for these metadata types. Location data (GPS), camera settings, and color profiles may be stripped during conversion.

About FLV to WAV Conversion
FLV (introduced 2002) and WAV (introduced 1991) are both video formats, but they differ in important ways. FLV (Flash Video) is a legacy streaming format — converting to MP4 is recommended for modern use. WAV is uncompressed PCM audio — studio quality with no data loss, but large file sizes.
Full Name: FLV uses Flash Video, while WAV uses Waveform Audio. Compression: FLV uses Lossy, while WAV uses None (uncompressed). Color Depth: FLV uses 8-bit, while WAV uses —.
When you convert FLV to WAV, the goal is to improve file compatibility across devices. Converting FLV to WAV maintains high quality with CocoConvert's optimised encoder settings. Understanding these technical differences helps you choose the right format for your workflow.
Your FLV file is decoded and re-encoded as WAV. The conversion involves 4 steps: (1) your flv file is uploaded and the format is validated, (2) the file content is decoded into its raw representation, (3) the data is re-encoded in wav format with optimal settings, (4) the converted file is ready for download.
CocoConvert's converter handles the entire pipeline server-side using FFmpeg, Sharp, and qpdf — battle-tested libraries used by streaming platforms and enterprise tools. Files are encrypted in transit and deleted within 24 hours.
This conversion is ideal when you Your FLV file won't open on a recipient's device or in an application, or when you A website, service, or platform only accepts WAV uploads. For the opposite direction, CocoConvert also supports WAV to FLV conversion.
How to Convert FLV to WAV
- 1

Select your FLV file by dragging it to the upload zone or using the file picker. Batch upload is available for multiple files.
- 2
Choose .wav
Set WAV as the output format. The converter uses optimal settings based on the FLV→WAV conversion profile.
- 3
Convert
The server-side engine decodes your FLV file and re-encodes it as WAV. Processing time depends on file size and complexity.
- 4
Download result
Grab your converted .wav file. Multiple output files can be downloaded together.
What Happens When You Convert FLV to WAV
The audio track is extracted from your FLV video file and saved as WAV. 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 WAV
Video frames, subtitles, and chapter markers are discarded
The WAV file is saved with preserved metadata (title, artist, etc.) where possible

Should You Convert FLV to WAV?
When to Convert
- ✓You need just the audio track from a video recording
- ✓You're creating a podcast or audio file from video content
- ✓You need a file that works in web browsers
- ✓You need maximum device and software compatibility
When NOT to Convert
- ✗You're hoping to improve image/audio quality — converting lossy to lossless cannot recover lost data
Common Mistakes When Converting FLV to WAV
"Converting FLV to WAV will improve the quality"
No. FLV has already permanently discarded data during compression. Converting to WAV preserves what's left but cannot restore lost detail. The file will just be larger.
"WAV will be smaller than my FLV file"
WAV uses no compression, so the output file is often larger than a lossy FLV. If you need a small file, WAV may not be the right choice.
