Notes

• The conversion is performed by LibreOffice in headless mode (soffice --headless).
• LibreOffice outputs files to the output directory with the same base name as the input. If your specified output filename differs, the file is automatically renamed.
• The input format is also validated against the supported formats list, though LibreOffice itself handles the actual format detection.
• Image output (PNG, JPG) may produce one file per slide depending on the LibreOffice version.
• Keynote (.key) support depends on the LibreOffice version; newer versions have better compatibility.
• The POTM and PPSM formats are also accepted as input (present in the source code's supported formats map).
