Why Compress PDF for Email β€” Fit Gmail, Outlook & Yahoo Limits?

Email providers like Gmail (25MB), Outlook (20MB), and Yahoo Mail (25MB) have strict attachment limits. Large PDFs β€” especially reports, portfolios, and scanned documents β€” often bounce back or fail to send altogether. Our intelligent compressor analyzes your PDF and reduces its size to fit within any email provider's limits, while preserving text clarity and image quality.

  • Yahoo Mail allows 25MB β€” same target as Gmail
  • For multiple attachments, compress each file individually
  • Use "Balanced" compression for the best quality-to-size ratio
  • For text-heavy reports, even Maximum compression keeps text perfectly readable
