how to convert a webarchive to pdf without cutting images at pagebreaks?

I collect some stuff from the internet and save it as .webarchive. But the text that webarchives contain couldn't be found by spotlight. So my "webarcive archive" is useless. I tried to save/print them as pdf but didn't find a way to save them as a onepager. So images are cut throug when a pagebreak occurs.

I don't want an Evernote Webclipper or Devonthink only to get working pdfs?

Any suggestions?

Thank you!
