Can I split by file size?

Yes. Choose “by size” and enter a target in megabytes. Ream packs pages into files that stay under the limit, which is what email attachments usually need.

Does splitting re-compress my pages?

No. Pages are copied as original objects, so text stays selectable and images keep their original resolution.

What is the page range syntax?

Comma-separate ranges, and use a dash for spans: 1-3, 5, 8-10. Leave it empty to split every page into its own file.

Split a PDF

Cut a document into separate files by page range, or explode it into one file per page. Cap the output size when an email limit is the real constraint — whichever fits how the document is actually structured.
