Understand, compare and shrink PDFs — using the same structural engine that powers Noteshelf's on-device compression.
A complete x-ray of one PDF — where every byte goes, images and duplicates, vectors, text, fonts, links, and a ranked optimization report with per-page drill-down.
Upload two PDFs — which is better optimized and why, a side-by-side of every metric, and exactly what content the two share (identical images, structures, page designs).
Shrink a PDF with the exact C cores shipped in the app — structural dedup + Flate recompression, lossless and verified — then see the before/after and download the result.
