    Getting a small enough file size

    I'm trying to change my LOunge userpic. I've cropped a jpg photo to 260 x 300 pixels, then resized it to 65 x 75, as required. I've then saved that and even saving it with the jpg quality factor reduced to 50, I still get a file size of about 8 KB which is bigger than the 5 KB maximum. I don't recall having this trouble before. Is it just a matter of reducing the jpg quality even further, or is there something else I ought to be doing?

    Here is the cropped section of the larger photo, before resizing.

    Re: Getting a small enough file size

    Thanks, Hans.

    So what am I doing wrong? I had originally done my resizing with GIMP and left the JPG quality at 85, which gave me a file size of about 9 KB. Reducing it to 50 still gave me too big a file. Following your lead, I have tried using IrfanView, and reducing the JPG quality to 30, but (a) that produces a fairly poor quality result, and a file size of 11 KB.

    Re: Getting a small enough file size

    I didn't do anything special:

    - I downloaded the picture you posted to my hard disk.
    - I opened it in IrfanView 4.20.
    - I selected Image | Resize/Resample.
    - I specified a width of 65; since Preserve aspect ratio was ticked, the height was automatically set to 75.
    - I clicked OK.
    - I selected File | Save As...
    - I left the Save quality at 100.
    - I clicked Save.

    See screenshots of the settings.

    BTW, setting Save quality to 85 in IrfanView results in an acceptable picture of only 1808 bytes.

    Re: Getting a small enough file size

    Thanks - this has enabled me to track down the difference between your settings and mine. I cleared all the options to keep EXIF data, etc, and that brought my file down to the same size as yours.
