Compress PDF to 1MB for Email
Email clients like Gmail and Outlook have strict attachment limits (usually 20-25MB). However, due to Base64 encoding overhead, files as small as 18MB can be rejected. Compressing your PDF to under 1MB guarantees it will smoothly attach to any email client without forcing you to use Google Drive or OneDrive sharing links.
