Dropbox "Compress _file_" option question

[jacaboo]

I use an image processing programme found on the internet . Install it and it becomes a selectable processing option.Then you can compress images of all formats in any program at all, including Adobe Acrobat . Just open an image, select compress ,then you can compress images ,the task will be finished in several seconds. if you haven't found a good choice , you can have a try. best wishes.
