Whenever I post a screenshot online or e-mail one, I have to convert it to .jpg to be sure that it will work easily. At the moment this involves me firing up Photoshop in Classic, which takes a while. Is there a piece of freeware that can do this simple task? I guess Graphic Converter can do it, but isn't that Shareware? If there's $$$ to pay, I can live with the system I currently use!

Ah....!!!

I'd only looked at 'Save As', which in Preview does nearly nothing.

Cheers!

Here's an even easier way to do it: Just hold down the Control key when you take the screenshot, so for example instead of Command-Shift-3 or Command-Shift-4, you'd use Command-Control-Shift-3 or Command-Control-Shift-4. This saves the picture on the clipboard instead of in a PDF file on the Desktop, so you can just paste it into your e-mail message instead of having to convert a PDF file.

What you are looking for is Kunvert

I agree that this is the best solution. I believe the image is sent as a .TIFF attachment, FYI.

Oh, forgot to mention that. If you really need to save the graphic in a particular format (.jpg, .tiff, .png, or whatever you like), you can use Command-Control-Shift-(3 or 4) to put the image on the clipboard, then go to Preview, and choose "New from Clipboard" from the File menu (command-N). Then you can export to your preferred format just as you would when converting from PDF, but you'll have one less garbage file to throw away later.

I rarely ever use Command-Shift-(3 or 4) without the Control key.

i used to use kunvert, but i found that this made higher quality jpegs (so i switched!)

I stick this applescript droplet into the finder's toolbar.

they're not the smallest JPEGs, but it works
[php]
-- Makes this script a droplet:
on open theFiles
convertToJPEG(theFiles)
end open

-- Allow Folder Action Scripting:
on adding folder items to this_folder after receiving added_items
convertToJPEG(added_items)
end adding folder items to


to convertToJPEG(added_items)
repeat with this_file in added_items
try
tell application "Image Events"
launch
-- get the parent folder of the image file
set the parent_folder to the container of this_file
-- derive new name for the new image file
set the new_name to my add_extension(this_file, "jpg")
-- look for an existing file
if (exists file new_name of the parent_folder) then
error "A file named \"" & new_name & "\" already exists."
end if
-- open the image file
set this_image to open this_file
-- save in new file. The result is a file ref to the new file
set the new_image to save this_image as JPEG in file new_name of the parent_folder with icon
-- purge the open image data
close this_image
end tell
tell application "Finder"
-- delete the original file
delete this_file
end tell
on error error_message
display dialog error_message
end try
end repeat
end convertToJPEG

on add_extension(this_file, new_extension)
set this_info to the info for this_file
set this_name to the name of this_info
set this_extension to the name extension of this_info
if this_extension is missing value then
set the default_name to this_name
else
set the default_name to text 1 thru -((length of this_extension) + 2) of this_name
end if
return (the default_name & "." & the new_extension)
end add_extension
[/php]

The best - and free - solution in my opinion is "QuickImage CM", which gives you a lot of nifty features accessible via the finder's contextual menu.

Like "Convert to" PSD/TIFF/PNG/PICT/BMP/JPEG (which is what you are looking for).
Or "Add/Remove Thumbnail Icon"
Or "Batch rename"

Highly recommended.
