How to send a large PDF by email without extra friction
Updated on May 9, 2026
Sending a large PDF by email sounds simple, but attachment limits often get in the way. This guide summarizes the fastest options to reduce file size and share the document more easily.
First step: reduce the attachment size
In most cases, the fastest fix is to compress the PDF before sending it.
That reduces upload time and helps prevent the attachment from being rejected because of size limits.
When to use each level
- Low for important documents where readability should stay stronger.
- Recommended for most work attachments.
- Extreme for urgent files that need to become as small as possible.
