FAQ
Can I compress to a specific size?
Yes. Select "Compress to specific size" and enter the target MB/KB; the tool will estimate the appropriate bitrate based on duration. The result is approximate, so actual size may vary slightly.
How to choose bitrate?
64–96 kbps is sufficient for speech; music should be 128 kbps or higher. M4A (AAC) typically sounds clearer than MP3 at the same bitrate.
Will sound quality be lost?
Lossy compression removes some detail; lower bitrates mean smaller files but more quality loss. Balance based on your needs.
