Can I transfer an iPhoto library (Mac) to a Windows computer and still be able to access the files?

Hi! I’m in the midst of some confusing computer issues.
I’m new to mac, and I’ve put a huge number of pictures into iPhoto. Now all of my old and new jpeg files exist in the iPhoto Library in Finder.
If a few years down the road I get a Windows laptop, will I be able to transfer my iPhoto Library to my Windows “My Pictures” and still be able to access the files? The Windows computer wouldn’t have iPhoto, so does that mean it wouldn’t be able to view them? I’m really nervous about losing the ability to access my pictures.
Would it be safer not to use iPhoto? I really like the program, but I don’t want to lose accessibility if I need to use Windows. I have two external hard drives that I frequently use to back up my files, and both are Mac/Windows compatible. The issue is just if the iPhoto Library will be transferable or not.
Thank you SO much in advance for any help! Sorry if I was repetitive – I’m trying to wrap my head around this!
