With your images, the -define jpeg:extent=85kb option completes for us without complaint with ImageMagick 6.8.5-4 (available later today) and returns a 84644 byte image. Note, there are several ways to affect the JPEG image size including -quality, -sampling-factor, -define jpeg:extent, and -strip ...

for this:

I use command:
/usr/local/bin/convert 11053304.jpg 11043461.jpg 11033336.jpg +append -colorspace sRGB -strip -coalesce -thumbnail 691x336^ -gravity center -extent 691x336 -fill none -stroke gray -strokewidth 1 -draw "rectangle 0,0 690,335" -format jpg test.jpg

in 6.7.4-10:
I get it 69335 bytes ...

My fault, BIG THX.

Because I need show picture on IE browser, other colorspace ie. CMYK is not supported by IE, so I must write --colorspace options.
But I use srgb，picture color still see have problem？

/usr/local/bin/convert /home/cache/filestorage/a9/10914457 -colorspace sRGB -strip -coalesce -thumbnail '768x1280 ...
