Works for me: libreoffice -env:UserInstallation="file://${tmp}" -headless --convert-to pdf "${file}"  Trying to convert files with password protection silently fails. 2016-01-25 13:36:24 +0200 answered a question convert-to command line parameter Hallo, I tried multiple things with LibreOffice 4.2.8.2-11.el6_7 (my company's default version). This one worked for me to convert calc file in .ods format to HTML:  libreoffice --headless -env:UserInstallation=file://${tmp} --convert-to html${myfile}  --outdir was not required in my experiments, but it works if you use it. The --convert-to command does not work for password-protected files, and there seems to be no option to pass a password. It simply fails silently with no hint to the user what went wrong. There are some other interesting commandline options, depending on your local env and requirements. --norestore suppress restart/restore after fatal errors. --quickstart starts the quickstart service --nologo don't show startup screen. --nolockcheck don't check for remote instances using the installation  It did not work for me to explicitly write the filter as html:HTML. This resulted in the error message Error: Please reverify input parameters...
