Frequently Asked Questions

What are the file size limits?
Free users can compress files up to 20MB. Premium users can compress files up to 50MB. Upgrade to Premium for higher limits and faster processing.
Will compression affect audio quality?
With our intelligent compression algorithm, you can significantly reduce file sizes with minimal quality loss. The compression level slider lets you balance between file size and quality according to your needs.
What's the difference between bitrates?
Bitrate determines the amount of data used per second of audio. Higher bitrates (320 kbps) preserve more detail but create larger files. Lower bitrates (128 kbps) create smaller files but may lose some high-frequency details. 192 kbps is generally considered the sweet spot for quality vs size.
Which format should I choose?
MP3 is most compatible and great for general use. OGG offers better compression efficiency. WAV is lossless but large - only choose if you need perfect quality for professional work.
How much can I reduce file sizes?
Typically, you can reduce WAV files by 90%, FLAC by 50-70%, and already compressed MP3s by 20-50%. The actual savings depend on the original file's quality and compression settings.
