Gmail has a 25MB limit. Most government portals cap uploads at 5MB. University submission systems reject anything over 10MB. If you've ever had a PDF bounce back because it was "too large," you know exactly how frustrating that is. Our free PDF compressor fixes that in a few clicks — no quality loss on regular documents, and no signup required. Students use it before uploading assignments, freelancers use it before emailing proposals, and office workers use it every time they need to attach that one bloated report. Choose how aggressively you want to compress, and we'll show you the exact before/after file size so you know what you're getting.

Frequently Asked Questions
How much can I reduce my PDF file size?
Depending on content, you can reduce PDF size by 30-90%. Image-heavy PDFs and scanned documents see the largest reductions. Text-only PDFs may compress less since text is already efficient.
Will compression affect my PDF quality?
Low compression keeps quality nearly identical to the original. Medium offers a good balance. High compression may slightly reduce image sharpness but keeps text perfectly readable.
Can I compress multiple PDFs at once?
You can process files one at a time using any individual tool, or use our Batch Compress feature to process up to 20 files at once and download as ZIP.
Is there a maximum file size limit?
Yes, we accept PDF files up to 50MB for compression. For larger files, try splitting them first with our Split PDF tool.
Why is my compressed PDF sometimes larger?
This rarely happens with PDFs that are already highly optimized. In such cases, the original file is returned unchanged.
