PDF Too Large for Email? Quick Tricks to Fix It

Most email providers cap attachments around 20–25 MB. Here’s how to shrink your PDF so it sends without errors.

1. Compress the PDF (Fastest Fix)

Start with compression. Many PDFs drop from 40–50 MB to under the email limit in a few seconds.

  1. Open the Compress PDF tool.
  2. Upload your large PDF.
  3. Choose a standard or higher compression level.
  4. Download the compressed version and check the file size.

2. Remove Pages You Don’t Need

Extra pages make the file heavier for no reason. Clean them out before sending:

  1. Open Delete pages.
  2. Upload your PDF and review all pages.
  3. Delete blank, duplicate, or irrelevant pages.
  4. Download the trimmed PDF and compress it again if needed.

3. Watch Out for Image-Heavy PDFs

Scanned documents and design-heavy files are mostly images. Reducing image quality slightly often cuts size by 50–80% while still looking fine.

Combine these steps: remove pages, compress the file, and keep an eye on email limits like ~25 MB for Gmail or ~20–25 MB for Outlook.

Tip: If your PDF is still too big, split it into two parts using Delete pages and send them in separate emails.
