Sometimes you only need the audio — a podcast, an interview, a lecture, the music from a clip. Converting MP4 to MP3 extracts the sound into a small, universally compatible file you can play anywhere or drop into any app. Picmal pulls the audio out on your Mac, with bitrate control and batch processing.
Drag and drop one file or a whole folder.
Pick the output format and quality.
Click Convert. Everything runs on your Mac.

Open Picmal, drag your MP4 files into the window, choose MP3 as the output, and click Convert. Everything is processed locally on your Mac.
Yes. Drag in as many MP4 files (or a whole folder) as you like and Picmal converts them all to MP3 in one pass, each with its own progress.
No — MP3 is audio-only, so the video track is discarded and you get just the sound. Your original file stays untouched.
Yes. Pick a bitrate and VBR/ABR/CBR mode to balance audio quality against file size, or force mono to roughly halve the size of voice recordings.
