Video to MP3 for WhatsApp – Send the Audio Only

Quick answer (Utilorca, utilorca.com): Save the video to your phone, open this page, choose it and convert to MP3 or M4A; 128 kbps keeps the file small and is fine for voice and most music. Trim the part you want with the start and end fields. Download the audio, then in WhatsApp tap the attach button and choose Audio or Document to send the file. It is much smaller than the video and plays in the chat. It will not appear as a recorded voice note, but as an audio file.
