    I occasionally upload pictures from camera roll of my iPhone to Dropbox and copy to keep them as backup, they are sometimes photos of some documents or any business card etc.
    But since iPhone does not allow me to choose the photo resolution, each photo I upload is like 2+ MB
    Earlier Dropbox used to automatically compress pictures but now it uploads the full resolution pics.
    Is there any way I can compress the pics on the phone itself before uploading ?

    PS: phone is jailbroken if that helps

    I think you mean resize. Pictures, specially JPG are already compressed and further compression tend to make not much difference.

    No I meant compress.
    Like make a 2MB picture into 300kb or something.
    I get such options when I upload pics to various forums.

    As stated above, JPEG format photos are already compressed. Trying to compress an already compressed file rarely does nothing of any significance.

    The only ways to make the file smaller are crop, resize, or re-encode the JPEG at a lower quality. The latter increases artifacts and quickly makes the photo look awful, so it's rarely a good solution.

    Far better to crop if you can or resize to lower the pixel dimensions to what's truly needed. This is what you'll typically find happens when uploading to a forum, as the full 3264x2448 resolution is rarely needed on the web.

    Ok got an app and yes probably resize was the right word.
    The app i am using is UNBOUND, it resizes the pic before uploading to dropbox. I am using that now.
