Compress PDF for email is the fastest way to fix the “file too large” error when sending documents. If your PDF is too big for Gmail, Outlook, or office email, you can reduce the file size in seconds without losing quality.

Email providers have strict file size limits. If your file is too large, it simply won’t send.
| Email Provider | Max Attachment Size |
