Other Methods to Reduce Size

Split the Document

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

  • Use Split PDF to divide by pages
  • Send as multiple emails
  • Recipients can merge if needed

Remove Unnecessary Pages

Only send what's needed:

  • Use Remove Pages to delete extras
  • Include only relevant sections

Use Cloud Sharing Instead

For very large files, upload to cloud storage and share a link:

  • Google Drive
  • Dropbox
  • OneDrive
  • WeTransfer

💡 Quick Tip

Most people won't notice the quality difference with medium compression. Try it first before using other methods.

What Makes PDFs Large?

  • High-resolution images: The #1 cause of large PDFs
  • Embedded fonts: Full font families add size
  • Scanned pages: Image-based pages are larger than text
  • Many pages: More content = more space

FAQ

Will compression hurt the quality?

Medium compression maintains good quality for viewing on screens. If the document will be printed, use low compression.

Can I compress password-protected PDFs?

You'll need to unlock the PDF first using the password.

What if compression isn't enough?

Try high compression, split the document, or use cloud sharing for very large files.
