What do I do if my PDF is too large to email?

If your PDF is too large to email, the quickest fix is splitting it into smaller files. Gmail and Outlook.com cap attachments at 25 MB, and sending adds about a third to the size, so aim for parts under roughly 18 MB.

Split by chapter or by a range of pages, then send the parts in two or three emails.

Drop the PDF into the splitter below and pick the pages for each part.
