How to Send a Large PDF by Email

You've tried to compress your PDF but it's still too large to email. Or maybe you need to send a file to someone but aren't sure they can receive a large attachment. Here are all your options.

Step 1: Always Try Compression First

Before reaching for alternative sharing methods, always run your PDF through a compressor first. Many PDFs can be reduced by 50–80%, which often brings them under email limits.

Go to compress-pdf.cc, upload your file, select Maximum compression, and check the result. If the compressed file is under 20–25MB, you should be able to email it directly.

Method 1: Share via Cloud Storage Link

This is the most professional and widely used approach:

• Google Drive: Upload your PDF to Drive, right-click it, select "Get link", and set sharing to "Anyone with the link can view". Paste the link in your email.
• Dropbox: Upload and use "Share" → "Copy link". The recipient can view or download without a Dropbox account.
• OneDrive: Upload and share via "Copy link" in the right-click menu.

Cloud links work for PDFs of any size and are the most reliable option for professional contexts.

Method 2: WeTransfer (Free, No Account Needed)

WeTransfer allows you to send files up to 2GB for free without creating an account:

1. Go to wetransfer.com.
2. Click "+" and select your PDF.
3. Enter your email and the recipient's email, add a message, and click "Transfer".
4. The recipient gets a download link that expires after 7 days.

WeTransfer is ideal for one-off transfers to people outside your organization.

Method 3: Split the PDF

If the content logically divides into sections (chapters, departments, date ranges), splitting the PDF into smaller files and emailing them separately is a clean solution. Free tools like PDF24 or Smallpdf offer PDF splitting. Combine this with compression for best results.

Method 4: ZIP Compression

Compressing a PDF into a ZIP file rarely produces significant additional size reduction, because PDFs are already internally compressed. However, if your email provider accepts ZIP files but has a different size limit for PDFs, zipping might help in edge cases. On Windows, right-click the file and select "Send to → Compressed (zipped) folder". On Mac, right-click and select "Compress".

Which Method to Use

• PDF is under 25MB after compression: Just email it directly
• 25MB–100MB: Use a cloud link (Drive, Dropbox, OneDrive)
• Over 100MB or no cloud storage available: WeTransfer
• Sending to many recipients at once: Cloud link is cleanest
• Sensitive/confidential document: Use a password-protected cloud share rather than WeTransfer
