Savings vary depending on the content. Text-heavy PDFs typically compress 20-50%. Scanned document PDFs may see smaller reductions since the images are already compressed.
Our compressor works by removing metadata and optimizing structure without re-encoding images. For significant size reduction on image-heavy PDFs, try converting to black and white or reducing image resolution first.
