Audio Speed FAQ
What is the Compress Audio tool?
+
This free online tool reduces your audio file size while maintaining good quality. Perfect for saving storage space or sharing files online.
What audio formats are supported?
+
We support MP3, WAV, AAC, FLAC, OGG, M4A, WMA, and other popular audio formats.
How much can audio files be compressed?
+
Compression rates vary by format and content. MP3 files at 320kbps can often be reduced to 128kbps with minimal quality loss.
Will compression affect audio quality?
+
Our smart compression minimizes quality loss. You can choose between different bitrates based on your needs.
Is there a file size limit?
+
Free users can compress audio files up to 50MB. Premium users have higher limits.
Can I convert a number of files at once
+
Yes. Free conversions handle one file at a time (merge tools accept two), while Pro unlocks batch processing of multiple files at once.
Does it work on mobile endpoints
+
Yes, our converter is fully responsive and works on smartphones and tablets. You can convert files on iOS, Android, and any other mobile platform with a modern browser.
Which browsers are covered
+
Our converter works with all modern browsers including Chrome, Firefox, Safari, Edge, and Opera. We recommend keeping your browser updated for the best operation.
Are my files kept private and confidential
+
Uploaded files are processed on our own conversion servers, nobody looks at them, and they are not shared. The upload and the converted file are both deleted automatically about 24 hours after the conversion, which leaves time to download the result. See /privacy/ for the full policy.
What if my fetch doesn't start
+
If your fetch doesn't start hands-free, try clicking the download button again. Make sure pop-ups are not blocked, and check your browser's download folder. You can also right-click the download link and check 'Save As'.
Will the standard be preserved
+
It depends on the formats. A lossless target such as PNG, WAV or FLAC keeps what the source holds; a lossy target such as JPG, MP3 or MP4 is usually re-encoded, which trades some detail for a smaller file.
Do I need to create an login
+
No account is required for basic usage. You can process files immediately. Creating a free account gives you access to your conversion history and additional features.
