Exported JPEG always larger than original JPEG

Jun 25, 2012 6:31 AM

I'm trying to export a JPEG so that the file size is smaller, for use on the web.  So the file I have is 1.1 MB.  I try to export via LR4 using the percentage slider, but no matter what percentage I use, the file size is always GREATER than 1.1 MB!  And if I try to limit the size by inputing a value, say 1000 kb, I get an error message saying I can't do that for some reason:

Also, this is not the case with just one file, it is numerous files.  Anyone have any ideas?

    Perhaps you have set the quality slider to 100? That could be part of the problem. If you want the size to be reduced, you will probably have to accept lower quality. Alternatively, since the photo is for the web, you could use the Image Sizing portion of the Export dialog box to reduce the dimensions of the image, which will make the output JPG smaller.

    In addition to looking over the size specified, this piece on what to set might help:

    No answer yet, this still baffles me.  I want a reduced sized JPEG, I don't care if it is a lower quality.  But I can't seem to do this using export functions in LR4.  Anyone?

    You probably need to post a screenshot of your export settings.

     

    I've just exported a raw NEF from a Nikon D800 - size on disk 42mb, pixel dimensions 7360 x 4912 - using quality setting of 70 (perfectly acceptable for the web) and resizing down to long edge of 1920 pixels (which should also be OK for web), the exported jpeg was 586kb.

     

    I've never used the "Limit file size" option, as it seems to be a bit temperamental, but I usually find an acceptable output size by using the quality slider in conjuction with resizing.

    If you set the quality slider to 70, you will get a JPG that has a smaller file size than the original. If you reduce the number of pixels in the photo, you will get a JPG that has a smaller file size that the original. Did you try any of these? I suggested both of them earlier in this thread.
