Compress PDF for email attachments
Email still rejects heavy PDFs even when cloud links are available. Here is how to shrink documents to a predictable KB size before you hit send.
Email providers tolerate large attachments until they do not. Gmail blocks outgoing messages above 25 MB; corporate inboxes often enforce much smaller limits on the receiving side. Compressing a PDF before you attach it avoids bounce-backs and keeps mobile recipients happy.
Pick a realistic KB target
- 500 KB - comfortable for most business PDFs under ten pages.
- 400 KB - common on government and licensing portals.
- 200 KB - tight, best for text-heavy documents.
Combine steps before sending
Need to merge screenshots into a PDF first? Use JPG to PDF, then compress on the all-in-one PDF page without a second upload.
