Frequently Asked Questions

Does volume adjustment affect quality?
The volume adjustment process itself does not affect quality, but final quality depends on selected output format and quality settings. If selecting lossless formats (WAV, FLAC) with high quality settings, can maintain original quality; if selecting lossy formats (MP3, AAC) or using lower quality settings, there will be some quality loss, but can minimize loss by selecting high quality settings. Volume adjustment only changes audio amplitude, does not change other audio characteristics.
Will my audio file be uploaded to the server?
No, all processing is done in your browser. Your audio file never leaves your device, completely protecting your privacy.
How large audio files can I adjust?
The tool supports audio files up to 1GB. For larger audio files, adjustment may take some time, depending on file size, selected volume adjustment value and output format. During processing, you can view progress to keep track of adjustment status. We recommend keeping the page open when adjusting large files to avoid interruption.
