Compress PDF for Email Attachment — Get Under 10MB Free
Overview
Corporate email servers commonly block attachments over 10MB. Gmail caps at 25MB and redirects larger files to Drive links. Outlook limits to 20MB. If your PDF report, presentation, or proposal is too large to attach, PDF Mavericks compresses it in your browser without routing the file through any external service. Most PDFs with images compress by 40 to 70 percent — enough to clear the typical corporate mail server limit.
How to Use This Tool
Open PDF Mavericks and upload your PDF. Select 'Medium' compression for a quality-size balance, or 'High' if you need to get well under a 10MB cap. The tool shows the compressed file size before you download so you can judge the result. If the file is still over the limit, use Split to send it as separate parts or trim unnecessary pages first.

What is the attachment size limit for major email providers?
Gmail: 25MB. Outlook and Hotmail: 20MB. Yahoo Mail: 25MB. Corporate Exchange servers: commonly 10MB, sometimes as low as 5MB. Always check with your recipient's IT policy for corporate email.
How much can I compress a PDF for email?
Compression savings depend on content. Image-heavy PDFs such as scans and presentations compress 50 to 80 percent. Text-only PDFs may only compress 10 to 20 percent. Try 'High' compression for maximum reduction before splitting.
What if the compressed PDF is still too large to email?
Use the Split tool to divide it into multiple smaller PDFs and send them as separate attachments. Alternatively, upload to Google Drive or Dropbox and share a link instead.
