You've written the email, attached the file, hit send — and get the dreaded "attachment too large" error. Here's how to handle every scenario.
Step 1: Compress First
Before anything else, try FreePDFNest Compress PDF. Most PDFs can be reduced by 40-90% with no visible quality loss. A 35MB report might compress to 4MB — well within any email limit.
Step 2: Split If Still Too Large
If compression isn't enough, use Split PDF to divide the document into smaller parts. Send each part as a separate attachment. Name them clearly: Report-Part1.pdf, Report-Part2.pdf, etc.
Step 3: Use Cloud Links
For very large files, upload to Google Drive, Dropbox, or OneDrive and share a link instead of attaching. This bypasses all size limits and lets the recipient download at their convenience.
Email Size Limits Quick Reference
Gmail: 25MB total (all attachments combined).
Outlook: 20MB (Outlook.com) or varies by organization.
Yahoo: 25MB.
Corporate email: Often 10-15MB, sometimes as low as 5MB.
Combining Both Approaches
The most reliable method: compress the PDF first, then if it's still over the limit, share via a cloud link. This gives your recipient a smaller, faster download while bypassing attachment limits entirely.
