Merging multiple PDF files into a single cohesive document streamlines sharing and archiving, but often results in an unmanageably large file. Large merged PDFs can exceed email attachment limits, slow down loading times, and consume excessive storage. A reliable PDF compression tool is essential for reducing file size without sacrificing readability or formatting.

- Smart Optimization: Automatically detects images, vector graphics, and text layers to apply lossless or lossy compression as appropriate — maintaining clarity while cutting size.
- Multiple Compression Modes: Choose between “High Quality,” “Balanced,” or “Maximum Reduction” to meet different distribution requirements.
