About this tool
Most email providers cap attachments at around 20–25 MB, and corporate servers are often stricter. A high-resolution scanned PDF blows past that easily.
The default target is 10 MB, a comfortable margin for almost any inbox. If your recipient has a lower limit, change it before compressing.

Questions
What is the email attachment limit?
It depends on the provider and is usually 20–25 MB per message; many companies set lower limits. If a message bounces for size, try a lower target.
Should I compress or share a link instead?
Sharing a link means uploading the document to a service. For sensitive content, compressing locally and attaching keeps the file under your control.
