How to Compress a PDF for Email
Learn practical ways to reduce PDF file size so you can attach and send PDFs by email.
Check the email limit first
Many email services limit attachments to around 20 MB or 25 MB. Before compressing, check the file size and the upload limit so you know how much smaller the PDF needs to be.
Use a PDF compressor
Upload the file to a free PDF compressor and download the optimized copy. If the file contains scanned images, compression may depend on the image quality inside the PDF.
Remove unnecessary pages
If the PDF contains extra pages, split the PDF first and keep only the pages you need. Removing pages can reduce size without lowering quality.
Use a sharing link for very large files
If the PDF is still too large, use cloud storage and send a secure sharing link instead of forcing it into an email attachment.
