Email to PDF Converter (formely EML to PDF Converter) Actions Status

This software can be used to convert email files (eml or msg) to pdf files. It can be used as a library, command line tool or desktop application with its GUI.

The conversion is done by parsing (and cleaning) the mime/structure, converting it to html and then using wkhtmltopdf to convert the generated html to a pdf file.

It also handles inline images, corrupt mime headers and can use a proxy.


You can download the lates binaries here.

There you can find a Windows setup.exe and a jar.
If you want to use the jar (e.g. for a non Windows OS) you need the wkhtmltopdf binary in the PATH.

How to Build

You need to git clone this repository. The build will fail if you remove the .git folder (e.g. download this as zip from github).

  • gradlew shadowJar
    Creates a single self contained Jar in build/libs

  • gradlew dist
    Same as gradlew shadowJar but additionally creates windows exe launchers in build/libs for gui and console mode. This task needs the Launch4j binary in the PATH.

  • gradlew innosetup
    Creates a windows setup in build/innosetup. This task needs the Launch4j binary as well as the Inno Setup issc.exe in the PATH.

  • gradlew check
    Executes the unit tests and generates various reports (jacoco, checkstyle, findbugs, jdepend, unit test report).

Date Formatting

Dates are formatted with the default locale. You can change it, e.g. by passing the VM argument -Duser.language=en-US similar to setting the timezone e.g. -Duser.timezone="Asia/Kolkata".
