WAV files are usually much larger. Conversion cannot restore detail already lost in MP3. Changing the sample rate does not improve the source quality.
Results are kept in memory (up to 128 MiB). Download and remove completed files to free space. On phones, use smaller batches.
Files stay on this device. No sign-in, server upload or AI credits are required. Refreshing or closing the page clears the list.
