+# mtt(multitool)
+
+A multi-tool that performs various operations on files within a directory. Currently, it supports the following features.
+
+## Usage
+
+`npm insatll -g @riq0h/mtt`
+
+## `mtt -r`
+
+Bulk renames filenames within a directory. When launched, `$EDITOR` is called, allowing you to flexibly edit with any editor.
+
+## `mtt -c`
+
+Compresses individual files within a directory. If no filenames are specified, all files will be targeted.
+
+## `mtt -i <files...> -p <value>`
+
+Resizes image files (`.jpg`, `.jpeg`, `.png`, `.gif`, `.webp`) within a directory. The `-p` option is required to specify the resize ratio.
