About This Scenario

Most corporate email servers (such as Microsoft Exchange and Google Workspace) enforce strict 20MB or 25MB attachment limits. Attempting to email a 60MB presentation or technical manual results in rejected bounce-backs. By splitting the large document into logical two or three parts (e.g., Part 1: Pages 1-40, Part 2: Pages 41-80), you can easily send the complete document across email threads without compression loss.

Step-by-Step Instructions

Complete this task in seconds using our on-device engine:

  1. Drop your oversized PDF document into the splitting stage.
  2. Define the page intervals for Part 1 (for example, pages 1 to 30).
  3. Click "Split PDF Locally" to generate the first email-ready document part.
  4. Repeat for subsequent page ranges and attach the smaller parts to your email.

Dividing the total page count roughly in half or thirds produces files that comfortably fall under standard 20MB-25MB email attachment limits.
