WAV to MP3 converter
한국어Pick a wav file and convert it to mp3. The file does not go to a server and the work finishes on this device.
What do you want to do
Pull the sound out of a video or recording as mp3, m4a or wav. No re-encoding of video, so it is fast.
Why convert
wav is not compressed, so the files are large. When a file is too big to send by email or chat, mp3 makes it much smaller.
What happens to the sound
mp3 drops parts of the sound that are hard to hear to save space. It is not identical to the original wav, but it aims for something that sounds fine for normal listening.
Questions
Is my file uploaded?
No. The wav file you pick does not leave your browser, and the conversion finishes on this device.
How much smaller does a wav get as mp3?
It depends on the sound. The screen shows the size of the file you picked and of the result, so compare them there. We do not quote a fixed number.
Is it slow, or are there files that fail?
The conversion runs on a single thread on your device, so long files take time. The engine is downloaded once at the start. The size limit depends on your browser and device memory.
