About this tool
Word, Excel & PowerPoint File Compressor made simple.
Modern Office files are ZIP-based packages. This tool recompresses package parts locally without rewriting their contents. It cannot optimize embedded photos or guarantee a smaller result; if there is no size reduction, it creates no download. Signed, encrypted, macro-enabled and legacy Office formats are not supported. Your original stays unchanged. Protective limits: 100 MB input, 200 MB expanded data and 5,000 parts.
