Solution
Convert the JPEG file to PNG with a tool like this:
ffmpeg -i DSC00033_FULL.JPG -vf "scale=200:-1" "DSC00033_Scaled.png"
Notes
In order to choose the size of the output PNG file, the scale option may be used.  I find the value 200: -1 to be effective for most JPEG files.
Why does it work?
The scale option makes an intermediate file for scaling the input, before the PNG compression occurs.
Normally, the scale operation does not result in an intermediate file (input and output are the same), so the scale operation is performed in two separate steps:
ffmpeg -i DSC00033_FULL.JPG -vf "scale=200:-1"
ffmpeg encodes the scaled-down version of the input file (DSC00033_scaled.png) into a new file.
If the scale option is missing, ffmpeg tries to apply the scaling directly to the JPEG input, which is impossible since the size of JPEG is fixed.
When the scale option is omitted, ffmpeg encodes the scaled-down version of the input file to a new file, and then the new file is immediately deleted.

From the manual
-vf [image_filter]
Applies the image_filter option to the image, where image_filter is the string of operations for one filter and consists of three parts separated by colons: the filter name, the filter_operation, and the filter_arguments.
  For example:
         -vf lavfi:color=blue:saturation=0.5:brightness=1.5
filters this image and applies the following image filter effects:
         Color - saturation: 0.5, brightness: 1.5
  Allowed image filter operations are:
         image2 - [one of the following!]
                        resize - [one of the following!]
                        blur  - [one of the following!]
