Frequently Asked Questions
What are typical email attachment size limits?
Gmail: 25MB, Outlook: 20MB, Yahoo: 25MB, ProtonMail: 25MB. Many corporate email systems have even stricter limits (5-10MB).
Will recipients be able to open compressed PDFs?

What if my file is still too large?
Options: 1) Use maximum compression, 2) Split into multiple smaller files, 3) Use cloud storage links (Google Drive, Dropbox) instead of attachments.
How much can I reduce the file size?
