About this compress PDF online tool
Large PDFs bounce from email inboxes and slow down uploads. LovePDF.online helps you compress PDF files in your browser. Choose Low, Medium, or High compression, preview the estimated reduction, and download a smaller file.
Compression runs locally. Your document is not uploaded to a server, which makes this a strong option for resumes, scanned forms, and shareable reports.

How it works
LovePDF compresses PDFs by rendering each page and rebuilding a lighter PDF with optimized page images. Lower quality settings create smaller files. Higher quality settings keep more detail. Because this method is lossy, text-heavy vector PDFs may look different after High compression. For many scanned documents, the size savings are worth it.
Step-by-step guide

2.Choose a compression level
Pick Low for better quality, Medium for balance, or High for the smallest size.
