How to Reduce PDF Size for Email Attachments
Email services limit attachment size. Aim below the stated limit because message encoding can add overhead during transmission.
Check the attachment limit
Confirm the maximum shown by the email service or recipient portal. Leave a safety margin, especially when sending several files.
Compress the PDF
- Open the Compress PDF tool.
- Start with balanced compression.
- Compare the result with the email limit.
- Inspect signatures, stamps, QR codes and fine print.
- Use strong compression only if needed.
Remove unnecessary pages
Use Delete PDF Pages for duplicate scans or blank pages, but never remove pages required for a complete official record.
If it is still too large
- Split the PDF into clearly named parts.
- Ask whether a secure upload link is available.
- Avoid repeated compression because image clarity can decline.
Check before sending
Verify names, dates, totals and page edges. Keep the full-quality original in a safe location.
