1. Preferably set up a virtualenv, as you do for a Python project.
2. Install playwright:
   1. pip install playwright
   2. playwright install
3. Run the script:
   1. python playwright-snapper.py -d snapshots https://akx.github.io
   2. snapshots/ will now contain PNG and PDF files.
   3. The script will not overwrite pre-existing files.

To run the script against multiple URLs in a text file, use xargs:

cat urls.txt | xargs python playwright-snapper.py -d snapshots

Pull requests welcome. :-)

• This script could be made more efficient by not using playwright screenshot etc., but the Playwright Python API instead, so the same session is used for both the screenshot and the PDF.
• The script could be made multi-threaded, so each URL is processed in parallel.
