Benefits of Compressing PDF Files

Email Limits: Standard email providers (like Gmail and Outlook) limit attachments to 20-25MB. Compressing helps you fit large documents into attachments.
Web Portals: Job boards, government portals, and school application forms often have strict 2MB limit limits.
Faster Loading: Smaller PDF file sizes render and open much faster for mobile users.

Frequently Asked Questions

Does compression degrade PDF text quality?

No. Our tool uses smart downsampling that compresses images and flattens metadata without affecting the readability of vector text.

Do you save a copy of my PDF file?

No. Your uploaded file is deleted from the server directory immediately upon completion of the compression script.
