I was saving old webpages as PDFs for years before I realized there's a better way

For the longest time, my digital time capsule method was to hit 'print to PDF' on any cool old site I found. I figured it was a solid snapshot. Then, about six months ago, I tried to show a friend a Geocities page I'd saved, and none of the hyperlinks worked. The whole interactive feel was gone, it was just a flat picture. That was the moment it clicked for me. I was basically taking photos of museum exhibits instead of preserving the artifacts. A quick search led me to the Wayback Machine's 'Save Page Now' feature, which actually captures the page's code and assets. Now I use that, and I also keep a simple text file with the original URL and date. Has anyone else found a better tool for making sure these old pages stay truly 'live' in their saved form?
