on run — display description and get a file
try
open ({choose file})
end try
end run

– This droplet processes files dropped onto the applet
on open these_items

set convertTo to (choose from list type_list with title “Format Conversion” with prompt “Select the format to convert the file(s) to:” default items {“html”} without multiple selections allowed) as text

repeat with i from 1 to the count of these_items

set this_item to item i of these_items

– Get the info for the item
tell application “System Events”
set the item_info to (get the properties of this_item)

set this_name to the name of the item_info
set this_place to the POSIX path of the container of the item_info
set ext to name extension of the item_info

end tell

– now check the file type
if (ext is in type_list) then
process_item(this_place, this_name, convertTo)
end if

end repeat

end open

– this sub-routine processes files
on process_item(this_place, this_name, convertTo)
– this_place is a POSIX path to the folder for this file
– this_name is just the file name with extension
– convertTo is a text string containing the new file extension

copy “cd ” & quoted form of this_place & “;textutil -convert ” & convertTo & space & quoted form of this_name to theCommand
do shell script theCommand

end process_item

I am a completely new and first Time Mac User and have been a Windows User for almost 10 years.. Just loved learning all this stuff..

Used to do a lot of such things back when Learnt DOS in Windows

being a unix admin I love learning new tricks and can see potential benefits in certain cases by using this thanks!

I think this goes hand and hand with being able to manipulate images and convert to different types try the following to learn more about that.
