What is PDF Compression?

PDF compression reduces file size without removing content. By optimizing images, removing metadata, and applying smart compression algorithms, you can reduce file size by 30-70% while maintaining readability. Compressed PDFs are perfect for sharing via email, uploading to websites, or storing on devices with limited space.

ToolForge's PDF Compressor offers three compression levels. Choose Low for documents with critical images, Medium for balanced results, or High for maximum compression on text-heavy documents.
