Troubleshooting
- File is not displayed. Make sure that it is a genuine WAV file and that the file extension has not simply been changed. The WAV format is supported.
- Multiple files are not accepted. You can select multiple WAV files at once or add them using drag and drop. If nothing happens, reload the page and try again.
- Conversion does not start. Check whether JavaScript is enabled in your browser. If necessary, test the page in a current browser such as Chrome, Edge, or Safari.
- Progress stops. The conversion runs completely locally in the browser. This may take some time for large or long WAV files. Wait until processing is complete.
- 100 percent reached, but no download possible. Check whether your browser is blocking downloads. If necessary, disable pop-up or download blockers and reload the page.
- Download all MP3 files does not appear. The button is only displayed if at least two files have been successfully converted.
- Very large file. WAV is uncompressed and can be very large. For long recordings, conversion may take several minutes. Close other programs to free up memory.
- File cannot be decoded. The WAV file may be corrupted or contain an unusual format. Export the file again as standard WAV with 16-bit or 24-bit.
- Conversion stops on mobile devices. The page must remain in the foreground until the conversion is complete. If you switch apps or lock the screen, the process may pause.
- No download on iPhone or iPad. Tap and hold the download button and select Save to Files. Downloads may be blocked in private mode.
- MP3 sounds different from WAV. MP3 is a compressed format. For highest quality, select 320 kbps in the options.
- Browser is slow to respond. Very large WAV files require a lot of memory. If possible, use a desktop browser for long recordings.
- File is being converted but does not appear in the list. Reload the page and add the file again. Make sure the upload is complete before clicking Convert.
If problems persist, try a different up-to-date browser or reduce the file size by using shorter sections.
