About compressing PDF files

A PDF balloons for two reasons: scanned pages stored as full-resolution images, and embedded fonts or metadata you never see. This tool tackles both: for text PDFs it re-streams the structure; for scans it re-renders pages at a sensible DPI. Pick a target size or use the quality levels. If a file genuinely can't shrink, we keep your original rather than hand back something bigger.
