Frequently Asked Questions: Compressing to For Email

Why did my 24MB PDF get bounced by Gmail when the limit is 25MB?

Email protocols encode binary files using Base64, which adds roughly 33% overhead. A 24MB PDF becomes ~32MB in MIME format, triggering email server rejections.

What is the safest target size for email attachments?

Targeting under 15MB guarantees safe delivery across enterprise email security gateways and spam filters.
