curl webpage and convert to markdown

having a dilemma with downloading webpages and converting them to markdown, for example: F=$(curl -O --silent https://www.guru3d.com/story/msi-teases-spatium-m560-ssd-with-innovative-nonmetallic-vc-cooling-technology | pandoc --extract-media="./"${F%.*}"_media" --from html --to markdown_strict -o "${F%.*}.md") HTML file downloads fine but the md file that gets created is not given proper name and is of no content. What is wrong in this syntax? Is there maybe some better or easier way of downloading webpages, converting them to markdown and storing html page images locally?
