Sending Large PDFs Without Email Attachments

Email caps attachments at 25 MB on most providers. Here are five ways to send larger PDFs cleanly.

Gmail, Outlook, Yahoo, Apple Mail — all cap attachments around 25 MB. For larger files you need different channels. Five reliable options.

Option 1: Google Drive link

If you have a Google account, you have 15 GB of free Drive storage:

  1. Upload the PDF to Drive
  2. Right-click → Share → "Anyone with the link" (or restrict to specific people)
  3. Copy the link, paste in your email

Gmail integrates with Drive — if you attach a large file, it auto-uploads to Drive and inserts a link. The recipient just clicks.

Pros: free for files up to 15 GB total, integrated with Gmail, recipient doesn't need an account.

Cons: requires a Google account to send.

Option 2: WeTransfer (no account needed)

WeTransfer lets you send files up to 2 GB without an account:

  1. Go to wetransfer.com
  2. Upload the file
  3. Enter recipient email
  4. Send

The recipient gets a link, downloads, link expires in 7 days. Free, no signup, works.

Pros: no account, clean UI, fast.

Cons: link expires; not suitable for long-term sharing.

Option 3: Dropbox or OneDrive link

Same idea as Drive but on Dropbox or Microsoft's storage. Both offer free tiers (2 GB for Dropbox, 5 GB for OneDrive). Upload, share link, recipient downloads.

Option 4: Compress first, then attach

For files in the 25-50 MB range, compression often gets them under the 25 MB attachment cap:

  1. Run Compress PDF at Medium
  2. Check the resulting size
  3. If under 25 MB, attach to email normally

The slight quality loss is usually invisible at screen-viewing zoom levels.

Option 5: Split and send pieces

If a file is genuinely too large and you can't use cloud storage:

  1. Split PDF into chunks of 20-25 MB each
  2. Email each piece separately with subject lines like "Report part 1 of 4"
  3. Recipient uses Merge PDF to reassemble

This works for offline recipients who can't use cloud storage. Awkward but reliable.

Choosing the right option

SituationBest option
Have Gmail, can use DriveDrive link (smoothest)
Sending once, no accountWeTransfer
Company uses Microsoft 365OneDrive
Recipient can't follow links (offline, restricted)Compress + attach, or split
Sending repeatedly to same personCloud storage link (long-term shareable)

Privacy considerations

Cloud-link sharing means the file lives on someone else's server for as long as the link is active. For sensitive documents:

  • Set links to expire (Drive supports this for paid Workspace accounts)
  • Restrict to specific emails (not "anyone with link")
  • Use Protect PDF to add a password — recipient needs both the link AND the password

For documents under NDA or with PII, consider whether free cloud storage is appropriate. Enterprise file-sharing tools (Box, Citrix ShareFile) offer better controls.

Bottom line

Drive link for Gmail users, WeTransfer for one-off shares, compression for borderline cases. Match the channel to the sensitivity of the content.
