The quality depends on the output format and bitrate you choose. Converting to lossless formats like WAV or FLAC preserves full quality. For lossy formats like MP3, you can select higher bitrates (256kbps or 320kbps) to maintain excellent audio quality.
Since processing happens in your browser, the file size limit depends on your device's available memory. Most modern devices can handle files up to several hundred megabytes. For very large files, we recommend closing other browser tabs to free up memory.
