What is Compress PDF?

Large PDF files can be a headache when submitting job applications, filing government forms, or attaching reports to email messages. Freeallpdf Compress PDF analyzes your document to strip redundant metadata, optimize internal stream compression, and downscale over-bloated raster assets.

Our engine offers three intuitive compression presets: Extreme Compression for maximum size reduction, Recommended Compression for the ideal balance between quality and small size, and Low Compression for high-fidelity archival.

Track your exact savings in real time with our live file size comparison metrics, showing you the exact percentage reduction before you download.
