How to Reduce PDF Size for Email Attachments
Struggling with large PDF files that won't attach to emails? Here's how to compress them quickly and easily.
Email Attachment Limits
Most email providers have attachment size limits:
- Gmail: 25 MB limit
- Outlook: 20 MB limit
- Yahoo: 25 MB limit
- iCloud: 20 MB limit
If your PDF exceeds these limits, you'll need to compress it or use cloud sharing.
Why Are PDFs So Large?
PDFs can become large due to:
- High-resolution images embedded in the document
- Multiple pages with complex graphics
- Embedded fonts
- Scanned documents saved at high DPI
- Layers and annotations
