M4R is lossy AAC, so WAV won't recover lost detail — it just expands the clip to uncompressed PCM for easier editing. Expect a bigger file.
About M4R
iPhone ringtone format
M4R is the ringtone format used by iPhone, essentially AAC audio limited to around 40 seconds, suited for creating custom ringtones.
- Usable directly as an iPhone ringtone
- Length-limited and single-purpose
About WAV
Uncompressed lossless format
WAV typically stores audio as uncompressed PCM, preserving the exact original signal. It is ideal for editing and professional use, but produces large files.
- Lossless and uncompressed
- Simple structure, easy to edit
- Large file size, not ideal for streaming
M4R to WAV FAQ
Will converting M4R to WAV lose quality?
M4R is already a lossy format, so converting to lossless WAV introduces no additional quality loss — existing compression artifacts remain but nothing new is degraded.
Will the file size change after conversion?
Converting to a lossless format (WAV) usually increases size, while converting to a lossy format (MP3, AAC) usually decreases it, depending on the chosen bitrate and sample rate.
How do I batch convert M4R to WAV?
Just drop multiple M4R files in; they are converted to WAV one by one via a queue. You can download them individually or as a single ZIP.
