WhatsApp limits file sharing to 16MB on mobile and 64MB on WhatsApp Web to ensure fast delivery and reduce data usage. High-quality audio recordings, especially those longer than 3-4 minutes, often exceed this limit.
Our tool uses intelligent compression algorithms specifically tuned for WhatsApp:
Our compression maintains excellent quality for voice messages and good quality for music. Most people won't notice any difference, especially on phone speakers.
After compression to 128kbps, you can send approximately 10-12 minutes of audio while staying under the 16MB limit.
WhatsApp voice notes are already compressed. This tool is for external audio files you want to share via WhatsApp.
Yes! WhatsApp Business has the same file size limits, so this tool works perfectly for business communications too.
Remove silence at the beginning and end of your audio to reduce file size even more.
For clips under 1 minute, consider using WhatsApp's built-in voice message feature.
Even compressed files upload faster on WiFi. Switch from mobile data if possible.
For very long recordings, consider splitting into multiple parts before compressing.
