Convert PDF to PNG without output file extension using ImageMagick

Question

It is simple to convert PDF file to PNG:

convert input.pdf -colorspace RGB -resize 800 output.png

However I have to skip extension in the file name, so I have tried with:

convert input.pdf -colorspace RGB -resize 800 output

but it generates me PDF file. How can I specify PDF type with convert argument ?

-type PNG

does not work.

Answer 1

Solution:

convert input.pdf -colorspace RGB -resize 800 png:output

This creates a PNG file named output.
