Here's everything about PDF sizes for email.

Attachment Limits

Most services allow up to 25MB. But smaller is better.

Recommended Sizes

  • Under 5MB — Ideal. Downloads quickly
  • 5-10MB — Acceptable for most recipients
  • 10-20MB — Only when necessary
  • Over 20MB — Consider compression or cloud sharing

Why Smaller Is Better

  • Saves recipient's mailbox space
  • Faster downloads, especially on mobile
  • Shows professionalism
  • Many corporate emails limit to 10MB

Quick Solution

Upload to FreeConversion, select High compression, download. Most documents will be well under 5MB.

Alternative: Cloud Links

For very large files, upload to Google Drive, Dropbox, or OneDrive and share a link instead. This also allows you to update the file later without resending.
