Frequently asked questions
Is Audio Compressor free?
Yes — completely free, with no signup and no watermarks. PL Tools is supported by a small number of non-intrusive ads.
Are my files uploaded anywhere?
No. Audio Compressor runs entirely in your browser, so your files never leave your device and are never sent to our servers.
Is there a file size limit?
Nothing is uploaded, so there's no upload limit — but very large files depend on your device's memory. Files up to about 100 MB work well on most computers; phones may struggle with much larger ones.
Which formats are supported?
Input: MP3, WAV, M4A/AAC, OGG/Opus, FLAC, WebM — anything your browser can play (up to 200 MB). Output: M4A (AAC) or OGG/WebM (Opus) at a lower bitrate — MP3 where your browser can create it.
Does it work on my phone?
Yes. PL Tools works in any modern browser on iPhone, Android, tablets and desktop — there's nothing to install.
