TrulyFreeOCR is a self-contained Java CLI that turns scanned PDFs and images into searchable, compressed PDF documents. It applies MRC compression (PNG background + JBIG2/G4 foreground) to reduce file size while preserving readability — no Ghostscript, no Python runtime, no cloud APIs needed. A single fat JAR + bundled Tesseract is all you need. Apache 2.0 licensed for worry-free commercial use.
