Javier Gutiérrez Chamorro (Guti)

Javier Gutiérrez Chamorro, publishing under the moniker “Guti,” focuses on lean, command-line friendly utilities that strip unnecessary bulk from digital assets without touching a single pixel or byte of actual content. His flagship, FileOptimizer, is a lossless compression hub that accepts more than four hundred formats—ranging from common Office documents, PDFs and raster images to EXE, DLL, EPUB, SVG and even emerging web formats like AVIF and JXL—then chains dozens of specialized engines such as PNGOUT, Ghostscript, mp3packer and Leanify to re-encode each stream at its theoretical minimum. Typical use cases include web masters shrinking entire folders of assets before deployment, system administrators slimming portable executables for faster network rollout, graphic designers batch-optimizing PSD and TIFF archives for long-term storage, and archivists preparing donation packages whose total size must fit strict hosting quotas. Because every transformation is verified with binary checksums, the workflow can be automated in CI pipelines or nightly scheduled tasks without fear of corruption. The interface is deliberately minimal: drag a tree of files, watch a real-time log of savings per codec, and collect a detailed HTML report at the end. FileOptimizer is available for free on get.nero.com, where downloads are delivered through trusted Windows package sources such as winget, always installing the latest build and allowing silent batch installation alongside other applications.
