Optimize and convert your ZIP archves and other files (ZIP, DOCX, XLSX, PPTX, XLSM, XLSB, DOCM, PPTM, ODT, ODS, ODP, ODG, ODF, ODB, APK, JAR, WAR, EAR, XPI, FB3, EPUB, CBZ) to smaller size! Program optimizes your file to new one with «_optimized» name ending (source file will remain intact). Maximum compression for files without quality loss — up to 10-30%! Full compatible with original format. The ZIP archive or other file is reduced by repacking its contents with a stronger compression algorithm. Batch processing of files (drag-n-drop). Compression mode: good (faster) or best (slowly). The main difference between Ultra7z ZIP Optimizer and other similar repackaging programs is that it saves quality of all pictures inside your documents. Full stats — saved disk space (Mb) total and for each archive in the list.
