WhatsApp and Telegram voice notes arrive as Opus files, which most desktop players can't open. Converting Opus to MP3 gives you a small, universally compatible audio file that plays on any device, app, or player. Picmal re-encodes locally on your Mac with bitrate control (VBR/ABR/CBR) and batch processing — no upload limits, no subscription.
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 Opus files into the window, choose MP3 as the output format, set your quality, and click Convert. Everything runs locally on your Mac.
Yes. Drag in as many Opus files (or a whole folder) as you like and Picmal converts them all to MP3 in one pass.
MP3 is lossy, and re-encoding from another lossy format can lose a little quality. Choosing a high bitrate (256–320 kbps) keeps it transparent for everyday listening.
Picmal is a one-time purchase of $15.99 — no subscription, no per-file limits, no watermark. Download to explore the interface; 14-day money-back guarantee.
