Why Use Our PDF Compressor for Exam Uploads?

100% Privacy Guaranteed: Your PDF is processed entirely on your device — we never upload your documents to our servers.

Many exam portals like Kerala PSC, UPSC, SSC, and banking exams have strict file size limits for document uploads. Our PDF compressor helps you meet these requirements without losing document quality.

The compression works by optimizing embedded images in your PDF while keeping text crisp and readable. Perfect for scanned documents, certificates, and mark sheets.
