What splitting a PDF is for
Extracting just some pages is handy to keep the chapter you care about from a manual, separate a single invoice from a summary, remove blank or advert pages, or send only the signed part of a contract instead of the whole document.
How to specify pages
Write the numbers separated by commas and use a dash for ranges: for example 1-3, 5, 8-10 extracts pages 1, 2, 3, 5, 8, 9 and 10 in that order. The pages are added in the order you write them. If instead you do not know which pages you need and only have to stay under a maximum size, there is Split a PDF by size.
Why splitting a PDF is needed
The two real cases are sending only the part that matters and staying under a portal's limit. In the first, splitting is also a privacy matter: attaching the whole contract when one page was needed means handing over everything else.
The third case, less obvious, is the single scan of several documents: the scanner produces one thirty-page PDF containing six separate documents, and filing it like that means never finding it again. Splitting it now costs five minutes, searching for it in a year costs far more.
Extracted pages do not bring everything with them
In the extracted parts bookmarks do not carry over, because they index the whole document, and internal links pointing to pages left behind become dead ends. That is normal and happens with any program, it is not a flaw of the split.
What does remain is selectable text, fonts and image quality: pages are copied, not redrawn or reconverted. An extracted page is identical to the original, which is why the size of a part is never proportional to its page count.
How much a part really weighs
Pages do not all weigh the same: in a scan, a page with a photo weighs a hundred times one of plain text. Splitting «into four equal parts» to stay under 10 MB nearly always produces one part that breaks the limit anyway.
There is also a fixed cost: each part carries its own copy of fonts and shared resources, so the sum of the pieces weighs more than the original. On a document with heavy embedded fonts, splitting into ten can grow the total by 30%.
