How PDF Compression Works
This tool re-renders each page of your PDF at the selected quality, then repackages into a new smaller PDF. With Custom target mode, it uses a binary-search algorithm to hit your exact size range.
- 100% private — processed entirely in your browser, never uploaded
- Quality presets for quick compression, or set an exact KB target
- Custom mode: binary-searches JPEG quality to land within your range
- If result is below Min KB, invisible padding brings it up to target
- Works on multi-page PDFs — processes each page individually
