Common Questions About Audio Compression

How to make MP3 under 25MB for email?

Upload your MP3 file and select the "Email" preset or choose "Medium" quality (128 kbps). This will compress your audio file to meet Gmail's 25MB attachment limit while maintaining good quality for voice and music.

Can I compress audio without losing quality?

Yes! Our smart compression reduces file size by 70-90% while maintaining excellent audio quality. Use "High" or "Highest" settings for music production, or "Medium" for general use. The difference is imperceptible on most playback devices.

Why is my audio file too large to send?

Different platforms have size limits: WhatsApp (16MB), Discord (8MB free/50MB Nitro), Email (25MB for Gmail), Telegram (2GB). High-quality recordings or long audio files often exceed these limits. Our compressor helps you meet any platform requirement.
