Batch File Organizer

Files are read locally to create a preview and ZIP. This browser tool does not rename or remove your originals. Its output is a separate ZIP copy that includes a CSV rename manifest.

You can preserve selected folders, sort files by type or modification month, change letter case, add numbering or prefixes, replace name text, and use name/date/index patterns. Exact duplicates are compared using file contents, not just names or sizes.

For reliable browser memory use, the current limits are 300 files, 30 MB per file, and 50 MB total. Folder selection depends on browser support; selecting files individually is available everywhere.
