Frequently asked questions
What is WhatsApp's audio file attachment size limit?+
WhatsApp allows audio file attachments (and all attachments) up to 16MB in standard chats. WhatsApp Business may have different limits depending on the plan. Voice notes (recorded in-app) are not subject to this limit as they are streamed through WhatsApp's internal system.
Why does WhatsApp compress my voice notes before sending?+
WhatsApp re-encodes voice notes to Opus at a low bitrate (typically 32 kbps) before delivery to reduce bandwidth usage. If you pre-encode your recording to Opus at 32–64 kbps before sending as a file attachment (not a voice note), WhatsApp may pass it through without re-encoding.
What audio formats can WhatsApp play directly?+
WhatsApp plays MP3, M4A, AAC, and OGG (Opus) directly in-chat on both iOS and Android. WAV and FLAC are typically not playable in WhatsApp's inline player and open in an external app instead. Convert to MP3 for the best in-app playback experience.
