Shrink PDF File Size Online
PDFs can be surprisingly large. Shrink them by stripping unnecessary metadata and optimizing the internal structure.
Your files are never sent to our serversHow it works
Large PDFs are slow to email, expensive to print, and consume mobile data. Our PDF compressor analyzes the internal structure of your document, removes unused objects, strips metadata, and applies lossless optimizations — all without reducing the visual quality of the content.
For publishing on the web
A multi-megabyte PDF linked from a website slows page load and hurts mobile visitors on limited data plans. Shrinking a downloadable brochure, report, or manual before uploading it keeps your site fast and avoids frustrating visitors with a slow download.
FAQ
Will shrinking affect print quality?
Optimization targets redundant data and bloated internal structure, not the visible content — printed output should look the same.
Can I compress password-protected PDFs?
The tool works on standard PDFs; password-protected files may need to be unlocked first since the browser can't read their internal structure while encrypted.
