Shrink PDF for Email Attachment Limit (Gmail, Outlook, Yahoo)
Trying to send an important PDF but getting a 'File too large' error from your email provider? Most email services like Gmail, Outlook, and Yahoo have strict attachment size limits that can delay your work.
Official Requirements & Limits
Gmail and Yahoo typically have a 25MB limit. Outlook.com and Office 365 often limit attachments to 20MB. If your PDF is even slightly over, it won't send, or it will be converted into a slow-to-access cloud link.
