Understanding Email Attachment Limits

Most email providers impose strict limits on attachment sizes:

Email ProviderAttachment Limit
Gmail25 MB
Outlook20 MB
Yahoo Mail25 MB
Apple Mail20 MB
Corporate emailOften 10-15 MB

When your PDF exceeds these limits, the email simply won't send. Here's how to solve this problem quickly.

Quick Solution: Online PDF Compression

The fastest way to reduce PDF size is using an online compressor.

Using AllPDFMagic Compress

  1. Go to AllPDFMagic Compress
  2. Upload your large PDF
  3. Select "High" compression for maximum reduction
  4. Download the smaller file
  5. Attach to your email

Most PDFs can be reduced by 50-80% without noticeable quality loss for screen viewing.

Other Methods to Reduce PDF Size

1. Reduce Image Quality

If your PDF contains many images, you can:

  • Convert high-resolution images to lower resolution
  • Change image format (TIFF → JPEG)
  • Remove unnecessary images

2. Remove Embedded Fonts

PDFs often embed fonts to ensure consistent display. Removing embedded fonts can significantly reduce size, but the document may display differently on systems without those fonts.

3. Split the PDF

If compression isn't enough, split the PDF into smaller parts:

  1. Use AllPDFMagic Split to divide pages
  2. Send as multiple attachments
  3. Or share via cloud link

4. Use Cloud Sharing Instead

If the file is still too large:

  • Upload to Google Drive, Dropbox, or OneDrive
  • Share the link instead of attaching the file
  • Recipients can view and download at their convenience

How Much Can You Reduce?

Original SizeCompression LevelResult
50 MBHigh~10-15 MB
25 MBMedium~10-12 MB
15 MBLow~10-12 MB

Results vary based on PDF content. Image-heavy PDFs compress better than text-heavy ones.

Tips for Creating Smaller PDFs Initially

  1. Optimize images before adding: Resize and compress images before including in documents
  2. Use "Print to PDF": Often creates smaller files than "Export to PDF"
  3. Avoid scanning at high DPI: 150 DPI is sufficient for most documents
  4. Remove hidden content: Delete unused layers and objects

Conclusion

Don't let large PDFs prevent you from sending important emails. Use AllPDFMagic Compress to quickly reduce file size and send your attachments without issues. It's free, fast, and requires no signup!
