Is there a good library which can convert doc file to pdf? There are some paid options available like cloudconvert, convertApi etc but I am looking for a free option. My python app is hosted on EC2 machine.
I also looked at python-docx library which can allow me to read the contents of the doc file, but writing the contents to pdf file will break the styling I suppose.

Here is a VBA solution for you (I don't know how to do this using Python).

If you need to convert multiple Word files to other formats, like TXT, RTF, HTML or PDF, run the script below.

Option Explicit On

Sub ChangeDocsToTxtOrRTFOrHTML()
 'with export to PDF in Word 2007
 Dim fs As Object
 Dim oFolder As Object
 Dim tFolder As Object
 Dim oFile As Object
 Dim strDocName As String
 Dim intPos As Integer
 Dim locFolder As String
 Dim fileType As String
 On Error Resume Next

 locFolder = InputBox("Enter the folder path to DOCs", "File Conversion", "C:Usersyour_path_here")
 Select Case Application.Version
 Case Is < 12
 Do
 fileType = UCase(InputBox("Change DOC to TXT, RTF, HTML", "File Conversion", "TXT"))
 Loop Until (fileType = "TXT" Or fileType = "RTF" Or fileType = "HTML")
 Case Is >= 12
 Do
 fileType = UCase(InputBox("Change DOC to TXT, RTF, HTML or PDF(2007+ only)", "File Conversion", "TXT"))
 Loop Until (fileType = "TXT" Or fileType = "RTF" Or fileType = "HTML" Or fileType = "PDF")
 End Select

 Application.ScreenUpdating = False
 Set fs = CreateObject("Scripting.FileSystemObject")
 Set oFolder = fs.GetFolder(locFolder)
 Set tFolder = fs.CreateFolder(locFolder & "Converted")
 Set tFolder = fs.GetFolder(locFolder & "Converted")

 For Each oFile In oFolder.Files
 Dim d As Document
 Set d = Application.Documents.Open(oFile.Path)
 strDocName = ActiveDocument.Name
 intPos = InStrRev(strDocName, ".")
 strDocName = Left(strDocName, intPos - 1)
 ChangeFileOpenDirectory tFolder
 Select Case fileType
 Case Is = "TXT"
 strDocName = strDocName & ".txt"
 ActiveDocument.SaveAs FileName:=strDocName, FileFormat:=wdFormatText
 Case Is = "RTF"
 strDocName = strDocName & ".rtf"
 ActiveDocument.SaveAs FileName:=strDocName, FileFormat:=wdFormatRTF
 Case Is = "HTML"
 strDocName = strDocName & ".html"
 ActiveDocument.SaveAs FileName:=strDocName, FileFormat:=wdFormatFilteredHTML
 Case Is = "PDF"
 strDocName = strDocName & ".pdf"
 ActiveDocument.ExportAsFixedFormat OutputFileName:=strDocName, ExportFormat:=wdExportFormatPDF
 End Select
 d.Close
 ChangeFileOpenDirectory oFolder
 Next oFile
 Application.ScreenUpdating = True

End Sub
