Quick answers

Frequently asked questions

Will lossless PDF compression reduce every file?

No. It repacks eligible objects and streams, so an already optimized or image-heavy PDF may stay the same size or grow.

Does this PDF compressor lower image resolution?

No. This tool uses lossless repacking rather than intentionally reducing image quality or resolution.
