Gmail lets you attach up to 25 MB, and Outlook.com up to 20 MB — and work email is often lower (Microsoft's business default is 10 MB). A scanned contract or a photo-heavy report can easily go over. Add your PDF here; the Recommended level usually shrinks scans by 70–90% while keeping them perfectly readable.

## Tips

- Smaller attachments arrive faster and are less likely to be blocked — aim for under 10 MB.
- Still too big? Split the PDF by size and send it in parts.
- For a black-and-white scan, tick Convert to black & white for an even smaller file.

## FAQ

### What's the maximum PDF size I can email?

Personal Gmail allows attachments up to 25 MB, and Outlook.com up to 20 MB for the whole email. Work accounts are often lower — Microsoft's default for business email is 10 MB — so smaller is safer.

### How do I make a PDF small enough to email?

Add it here and click Compress PDF. Recommended works for most files; choose Extreme or Exact size if you need it smaller.

### What if it's still too large after compressing?

Split it into several files with Split PDF by size and send them in separate emails, or share a cloud link instead.

### How do I reduce a PDF to 200 KB (or 100 KB)?

Add your PDF, choose "Exact size (KB / MB)", type 200 (or 100) and click Compress PDF. The tool tries different quality settings and gives you the best-looking version that fits under your limit.
