The size efficiency of PDFs is always astounding to me. A small book with full typesetting and everything can be smaller than a phone camera jpeg.

[@bill_the_duck]

Text is pretty small. PDFs can be hugely bloated but text with basic formatting doesn't require much at all. The text itself and a little bit of metadata about formats and positions and pages.

[@GreatMossWater]

Books do have a lot of the same words that can be repeated with a character or symbol, like using abbreviations but in code.

[@nathanlakeland2953]

@@GreatMossWater even without huffman codes / similar compression methods text is really small, each character is in 1 of 256 states, whereas with an image every pixel has 3 colour values which are each in 1 of 256 states. This means that with no compression a single pixel of an image is equivalent to 3 characters.

[@enhzflep]

@hedgeearthridge6807 I used to print Excel files to PDF - my invoices were commonly about 50kb. I then read the Adobe PDF v1.6 specification doc and worked out why these files were so large. Wrote my own library in Javascript, removed Excel from the process entirely, reduced human-interaction to just data-entry (thus reducing the scope for human-error in the process) while speeding up the production of and reducing the final size of my pdfs. My invoices are now around 2kb and are produced in about 1/4 of the time. I think I enjoyed reading that spec document far too much! 😆

[@mtarek2005]

@@nathanlakeland2953 ignoring that Unicode is a bit bigger, most people write in only a fraction of that in repeating pattern we call words and considering that PDFs are compressed files using older zip deflate or "newer" lz4, zips usually take not that much space even when fonts are included in the file since most fonts are vector graphics which take up very little space and many PDFs only contain a fraction of the font

[@resresres1]

I've made PDFs for my work that were on the order of 200,000+ pages that i ended up having to break down the file because adobe bogged down and ran way too slow with that many pages.

There's a 1.6GB PDF file on our server. Discovery in a legal case. The best part is that the idiot who put it together attempted to redact things by drawing black boxes over things. Thank you kind person for showing us where the juicy stuff was, and allowing us to see it!

[@SnekInASuit]

this is exactly the kind of stuff I like hearing about. it reminds me that the job I do isn't JUST expertise, or passion, or smarts, but the intersection of all of those things at once. the fact that someone's job can be "computers" in any capacity, and they're able to have such a misunderstanding of even the basic tech they're working with that they're able to *put a black box over some text without removing said text* and think "that oughta do it", it serves as a small, albeit powerful reminder for me, that even the most automatic, zero-thought professional impulses I have every day on the job are things that are absolutely worth being paid for. the best part is that experience just builds upon all that, and if I'm worth it as I am now, it's not going to get any less true. rambling aside, long story short, I wish I could tell every self-taught IT kid out there the same. if you care about your work, and you're always seeking to expand your knowledge, and can accept when you're wrong and learn better, then you're already better than everyone your age who's just doing it because they think it's an easy salary.

The game-book is just a Choose-Your-Own-Adventure book in PDF form, which already exist, but this one is just bigger and more tedious to make because of the graphics and interface requiring a lot more pages. 🤷 (CYOA aren't the only ones like this, they were just the biggest and most famous; there was also the popular _Fighting Fantasy_ series, but also plenty of other game-books, including official D&D ones.

The comment on the print planet forum was from Dov Isaac’s- he was one of the creators and scientists from Adobe who made the PDF format.

[@PauxloE]

My company has a tool which creates a PDF with GTIN barcode labels to stick on fashion items. One (tiny) page per item, for a big purchase order (i.e. what we are ordering from our supppliers, to later sell to customers). So when you order like 200 articles, and 1000 items for each, you easily get 200000 pages. For smaller orders, people do print them (on a label printer). (For the big orders we usually got some third-party printing service where we deliver the data in a different way.) I think we should have used the pagegroup trick to make these less huge files, as many pages are just duplicated, but we didn't yet.

I was recently preparing pdf with ~32000 pages, including maps and images, with resulting file size of 32 gigs. It was unusable at all.

What would be a better way to store information? My company runs reports that scour our entire database (which is spaghetti code) which literately freezes production.

Doesn't your database solve that problem? And alternatively, making a program that reads and displays some serialized data, like FlatBuffers, Protocol Buffers, or even something like JSON if it's not that large

I imagine there could also be a huge PDF file that are compilations of ebooks.
