Compress Audio Online
Sound carries far less information per second than video, which is why audio offers the steepest size cuts of any media type — provided the source still holds uncompressed or wastefully-encoded data. A WAV has everything to gain; a tight MP3 has almost nothing. This page reads what it is given, compresses in the browser, and the result row says honestly which kind of file you brought.

Perguntas frequentes sobre compressão de Audio
Can audio be compressed without hearing it?
At transparent settings, for speech and most casual music listening, yes — the loss concentrates in detail that ordinary equipment does not resolve.
Why did my file barely shrink?
Because it was already an efficient lossy encode — squeezing that again spends quality for few bytes rather than recovering slack.
Will my original file be changed?
The result is downloaded as a separate file. Keep your original until you have checked the Compressed audio.
What should I check before using the result?
Open the Compressed audio in the application that consumes it and spot-check the parts that matter to you; the original file stays untouched if you need to re-run with different options.
