progressive jpeg to progressive jpeg

Post by imagenki »

I am curious if source file were a progressive jpeg and I resized it, would the converted jpeg retain progressiveness?
Thanks in advance!

I tested and it turned out conversion wipes out progressiveness.

This is from original file:
Interlace: JPEG
This is from converted file:
Interlace: None
