Comic Strips is a community for those who love comic stories.
The rules are simple:
- The post can be a single image, an image gallery, or a link to a specific comic hosted on another site (the author's website, for instance).
- The comic must be a complete story.
- If it is an external link, it must be to a specific story, not to the root of the site.
- You may post comics from others or your own.
- If you are posting a comic of your own, a maximum of one per week is allowed (I know, your comics are great, but this rule helps avoid spam).
- The comic can be in any language, but if it's not in English, OP must include an English translation in the post's 'body' field (note: you don't need to select a specific language when posting a comic).
- Politeness.
- Adult content is not allowed. This community aims to be fun for people of all ages.

Well, for thot pics, there’s always more jpeg. For everything else, there’s lossless data formats.
Even with jpeg, you only lose data each time it's encoded. If you save the file instead of taking a screenshot, the quality remains the same.
That said, I don't know if there's a digital storage method widely used that will last longer than a book without some sort of active aspect to the storage (like copying the files to a new medium every now and then).
I think punch cards are one that can, but they aren't used much anymore due to poor density and speed, plus being susceptible to literal bugs. It's possible to encode digital information into carved rock, but that would also have density issues (higher density means less reliability because the amount of damage required to make it unreadable is lower).
I think there's a good chance that a lot of the knowledge we have today could be lost entirely if civilization collapses to a certain degree just due to how we store it.
We do have some backups.
