I have first image with dimensions:30x40 and second 500x200
I want to append small image to the big one (using -append) but before appending I want to resize canvas (not image) of the small image to second image dimensions (500x200). Is it possible to do this with a single command?

Depends upon how you want it centered and what background color for the canvas. Here is one example
convert largeimage smallimage \
\( -clone 0 -fill white -colorize 100% \) \
\( -clone 2 -clone 1 -gravity center -compose over -composite \) \
-delete 1 -append resultimage
These are Unix command syntax. For windows see
