How to make a file smaller for email

  1. Identify whether the attachment is an image, a PDF, or many files.
  2. Compress images with Compress Image; compress PDFs with Compress PDF.
  3. ZIP multiple files only after each piece is already lean.
  4. Retry the email send.
  5. If it still fails, share fewer pages or a single compressed PDF.

Why it matters

Getting the message through beats sending the perfect uncompressed master.

Tips

  • Many providers struggle beyond roughly 10–25 MB total—targets vary.
  • Inline screenshots in the email body can also bloat sends.
  • Temporary file share links help when attachments remain too large.
