by Hyper Compress is a PDF compression engine built around verified transformations and document fidelity. It offers a true lossless mode and visual preserving presets, verifies every change that can affect how a page looks and rolls it back when the check fails, and never returns a file larger than the original.
Benchmarked against Ghostscript, MuPDF and qpdf on 2,104 real world PDFs (27,352 engine runs), it achieved median size reductions of 22.4% in lossless mode and 52.3% at the 300 DPI preset, with the lowest corruption rate of any engine measured. It ships as a CLI, Node SDK, C library, self hosted service and a WebAssembly build that runs in the browser.
