MRC PDF Kompressor converts scanned images into compact PDF files using
Mixed Raster Content (MRC): the page is split into a high-resolution text
mask (JBIG2, pattern-safe without character substitution), separate colour
text layers for stamps and headings, and a smoothed, downscaled background
(JPEG 2000 or JPEG). Typical results are 90-95 % smaller than the original
scan while the text stays crisp. Optional text recognition (OCR, runs
locally) adds an invisible text layer so the PDF becomes searchable.
It also converts PDF files (e.g. from copiers) into small, searchable
PDF/A, keeping existing text, links and bookmarks.
Supports PDF/A-1b, -2b, -2u, -3b, -3u and PDF/A-4 output (validated with
veraPDF), multi-page TIFF, batch
processing of folders, custom profiles and a split-view GUI with live
preview. The command line is fully scriptable (exit codes, progress,
profiles). Free for private individuals and small businesses (PolyForm
Small Business License).
