WHY USE THIS TOOL

Reduce audio size without wrestling with codec commands

Bitrate and codec choice are the main levers for compressed audio size. This workflow keeps those controls visible and everything else out of the way.

Lower bitrate

A lower bitrate generally creates a smaller compressed audio file.

Choose the destination codec

MP3 maximizes compatibility while AAC, OGG and OPUS can fit modern workflows.

Keep a lossless original

Compress a copy when the source matters so you retain a high-quality master.

HOW IT WORKS

How to compress audio

1
Upload audio
Choose MP3, WAV, FLAC, M4A, AAC, OGG, OPUS or another supported audio file.
2
Pick format and bitrate
128 or 192 kbps are useful starting points when size matters.
3
Compress and download
VideoHop creates a new smaller-format audio file.

Good to know

Lossy compression can reduce quality. Keep the original when it is important, especially before making aggressively small versions.
