Frequently Asked Questions

Does audio conversion affect quality?
Quality impact during conversion depends on the selected format and parameters. Conversions between lossless formats (WAV, FLAC) will not lose quality; conversions between lossy formats (MP3, AAC) or from lossless to lossy will have some quality loss, but can be minimized by selecting higher bitrate (such as 320k); converting from lossy to lossless format cannot restore lost quality.
Will my audio files be uploaded to the server?
No, all processing is done in your browser. Your audio files never leave your device, completely protecting your privacy.
How large audio files can I convert?
The tool supports audio files up to 1GB. For larger audio files, conversion may take some time, depending on file size, selected format and parameters. During processing, you can view progress to keep track of conversion status. We recommend keeping the page open when processing large files to avoid interruption.
