How to Split Large PDFs for Email Attachments

Reduce PDF file size by splitting to meet email attachment limits.

Splitting PDFs for Email

Email providers limit attachment sizes (typically 10-25MB). When your PDF is too large, splitting is the solution.

Gmail25 MB
Outlook20 MB
Yahoo25 MB
Corporate10-15 MB (varies)

Strategies

1. Split by sections: If sending a report, split into sections and send multiple emails. 2. Extract relevant pages only: Don't send the entire 100-page document if the recipient only needs pages 5-12. 3. Split into equal parts: Break a 30MB PDF into three 10MB files.

After Splitting

    • Name files clearly: "Report_Part1.pdf", "Report_Part2.pdf"
    • In your email, mention the total number of parts
    • Consider using file compression if individual parts are still large
    • For very large documents, consider cloud storage links instead
