Why compress audio for WhatsApp?
WhatsApp has strict limits on how big of a file you can send to your contacts. If you try to send a long high quality audio recording, you will usually get an error message telling you the file is too large. This is especially common if you record voice memos in uncompressed WAV format on your phone.
This tool takes your large audio files and compresses them down into a much smaller MP3 file so you can send them on WhatsApp without any issues.
How to shrink your file
Just tap the upload button and select the audio file from your device. Our tool will automatically process the audio and reduce the bitrate to shrink the file size down to a WhatsApp friendly size.
Once it is done, you can download the new MP3 file and share it straight into your WhatsApp chats. The process happens entirely in your browser, so it is incredibly fast and you do not have to worry about your personal audio files being saved on a random server.
Frequently Asked Questions
What format is best for WhatsApp?
MP3 is definitely the safest bet. It has great compression so the files stay small, and it is universally supported, which means whoever you send it to will be able to play it without any problems.
What is the actual file size limit for WhatsApp?
WhatsApp typically limits audio and video file uploads to 16MB on mobile devices. Our tool targets a safe size well below that limit so you never get an error message.
Will this delete the file from my phone?
No. The compression happens on a copy of the file. Your original, high-quality audio recording will stay perfectly safe and untouched on your device.
