Why Is My WAV File So Large?
Large WAVs are normal — they prioritize fidelity over size. Delivery formats should be lossy or compressed lossless.
Problem: A voice note or export WAV is too big to email or upload.
Solution: Convert WAV → MP3 for sharing, or FLAC for lossless archives that are still smaller than WAV.
Uncompressed audio
PCM WAV stores samples directly. Minutes of audio become tens of megabytes quickly.
Share vs archive
MP3 for chat/email; FLAC when you need lossless but smaller than WAV.
From video
Prefer extracting MP3 from video when you only need listen-only delivery.
Fix it in three steps
- Convert WAV → MP3. Pick a bitrate suited to speech or music.
- Keep WAV. Archive the master.
- Optional compress. Use the audio compressor for further MP3 shrinks.

FAQ
Why is my WAV file so large?
WAV is typically uncompressed. Convert WAV to MP3 for sharing (keep WAV/FLAC as masters). Zipping WAV helps less than a proper audio encode.
Is FLAC smaller than WAV?
Usually yes — lossless compression without throwing away audio.
