Compress Images for Email

Gmail allows 25MB per message, Outlook 20MB, and many corporate mail servers far less. Several untouched phone photos blow past those limits quickly.

Target 1MB per image and you can attach a dozen photos comfortably while they still look great on screen.

Attachment limits worth knowing

Plan for the strictest server in the chain, not the most generous.

  • Gmail: 25MB per message
  • Outlook / Microsoft 365: 20MB, often lowered by administrators
  • Corporate and university mail: frequently 5–10MB
  • Contact forms: often 2MB per file

Why not just use a cloud link?

Links expire, require sign-in and sometimes get blocked. A compressed attachment simply arrives — and compressing it here means the photo is never copied to a third-party server first.
