Compress a PDF Before You Email It

Email providers often reject large attachments. Compressing a PDF reduces image-heavy pages and optimizes structure without needing desktop software. That is especially common with phone scans, slide decks exported to PDF, and multi-invoice packets.

Upload your file to Compress PDF, download the smaller version, and attach it. If quality is critical for print, keep an uncompressed master copy and only send the compressed variant to inboxes with size limits.

For scanned documents, compressing after cleanup usually yields the best balance of size and readability. Remove blank pages and rotate misoriented pages before you compress so you are not spending bytes on content you do not need.

If the attachment is still too large, split the PDF into parts or convert heavy pages to images, resize them, and rebuild — FileToolsHub image and PDF tools can cover that multi-step path without leaving the hub.
