How to Send a Large PDF by Email — 5 Free Solutions

Published October 7, 2025 • 5 min read • PDF Tips

You need to email a PDF but it is too large. Gmail says "attachment too large," Outlook rejects it, and you are stuck. This is one of the most common file problems people face every day. The good news: there are several free ways to solve it.

Quick Answer: Gmail's limit is 25 MB, Outlook is 20 MB. If your PDF is too large, compress the images inside it using the Image Compressor, split it with Extract PDF Pages, or remove unnecessary pages with Delete PDF Pages.

Email Attachment Size Limits

Gmail: 25 MB (auto-switches to Google Drive link if larger)
Outlook: 20 MB
Yahoo Mail: 25 MB
Apple Mail / iCloud: 20 MB (uses Mail Drop for larger files)
ProtonMail: 25 MB

5 Free Ways to Send a Large PDF

1. Compress the Images in Your PDF

Most large PDFs are big because of high-resolution images. If your PDF has photos, scanned pages, or graphics, compressing those images can cut the file size by 50-80%.

Use the Image Compressor to compress images before building the PDF, or rebuild the PDF with optimized images using JPG to PDF.

2. Remove Unnecessary Pages

Does the recipient actually need all 50 pages? Often you only need to send specific sections. Use Delete PDF Pages to remove pages you do not need, dramatically reducing file size.

3. Extract Only the Pages You Need

Instead of sending the whole document, extract just the relevant pages with Extract PDF Pages. Send a 5-page extract instead of a 100-page document.

4. Split Into Multiple Smaller PDFs

If the recipient needs everything, split the PDF into parts. Extract pages 1-25 as Part 1 and pages 26-50 as Part 2. Send them as separate attachments or emails.

5. Use a Cloud Link Instead

Upload the PDF to Google Drive, Dropbox, or OneDrive and share a link. This avoids attachment limits entirely. Gmail does this automatically when files are over 25 MB.

Quick Decision Guide

PDF has lots of images? → Compress images first
Only need some pages? → Extract or delete pages
Need to send everything? → Split into parts or use a cloud link
Scanned document? → Re-scan at lower DPI (150-200 instead of 300+)
