About this WhatsApp voice note converter
WhatsApp voice notes are mono, narrow-band and small — designed to send fast and play back instantly. This tool re-encodes any audio file to those specs (mono, 32-48 kbps MP3 / AAC) so you can attach it as a voice note in WhatsApp, Telegram, Signal or any other messenger that accepts MP3 audio messages.
Output is small — a 1-minute voice note ends up under 300 KB. Fast to send over slow networks; instant to download for the recipient.

WhatsApp voice note FAQ
Can I send the file as a real voice note (not as an attachment)?
Behaviour varies by platform. WhatsApp shows MP3 attachments inline as audio; Telegram lets you long-press to send as a voice message. The encoded file works in both modes.
Why mono?
WhatsApp voice notes are recorded in mono. Mono cuts file size in half compared to stereo, with no audible loss for spoken-word content.
Won't OPUS be smaller?
Yes — slightly. MP3 at 48 kbps mono is close enough in size and works in every messenger.
Is my file kept private?
Yes. We don't analyse or index your audio.
