Spec score 9.4 #1 of 39 in PDF Compression Software

What it is

BentoPDF Hyper Compress is a PDF compression engine intended to reduce file size while preserving document content. It is available as a command-line tool, Node SDK, C library, self-hosted service, and WebAssembly build, with web, Windows, macOS, Linux, API, and self-hosted platforms listed. The engine includes a lossless mode and is stated never to produce a file larger than the original. Its maker reports a 0.39% corruption rate across 2,104 real-world PDFs in its benchmark. Open-source projects under an AGPL-compatible license, self-hosting, and internal use are covered by AGPL-3.0; no price is listed for that plan. A commercial license is needed only to ship the engine inside closed-source software. Annual commercial plans are Solo at $99 a year, Indie at $199 a year, Business at $499 a year, and OEM at $1,999 a year. Purchases provide a ZIP archive with complete source code, not a license key. Active commercial licenses include releases published during the license term.
