Compress PDF for email
Shrink a PDF before you attach it. Gmail and Outlook often cap attachments around 20–25 MB. This page starts on our smallest setting.
How to compress a PDF for email
1.Choose the PDF you want to attach, or drop it into the tool.
2.Add more files or rotate pages if you need to, then open compression levels.
3.Leave Extreme compression selected for the smallest attachment, or pick balanced quality.
4.Download the smaller PDF and attach it to your message. Server copies are deleted after 60 minutes.
FEATURES
Built for attachments
The job is the same Compress PDF compressor. This page starts on the smallest setting because email size caps are the usual reason people land here.
Inbox size limits
Many providers reject attachments above about 20–25 MB. Extreme compression is the best first try. It still cannot make every scan tiny.
Keep it readable
If the email is a contract or a one-page letter, balanced quality is often enough and looks cleaner.
Deleted after 60 minutes
We keep the upload and the result only long enough for you to download them.
No watermark
The file you attach does not get a MyPDF stamp. Free accounts get 5 jobs a day.
Same tool, email copy
Need a different starting quality? Open Compress PDF. Need a 2 MB cap? Use Compress PDF to 2MB.
Make a PDF small enough to send
Email is still a common way to send a PDF, and attachment limits are why people search for this page. MyPDF compresses the file with Ghostscript on the server, then you download it and attach it yourself. We do not send the email for you.
This page pre-selects Extreme compression (level 3). That is the smallest quality we offer. A presentation with photos may still be large. If it is, split the PDF or send a link instead of an attachment.
Working files are deleted after 60 minutes. There is no watermark. Free accounts get 5 jobs a day. If the original is over 25 MB, use Pro, Team, or a $5 day pass before you upload.
