File Renamer
Rename multiple files with find and replace, case conversion, direct editing, or a two-column CSV. Everything stays in your browser.
1. Add files
2. Rename
The two modes are alternatives. Uploaded files stay available and each mode keeps its own preview.
Each application starts from the original name. Longer find matches have priority.
Find/replace, letter case, prefixes, suffixes and numbering are applied together, always to the original name. You can also edit names manually in the final table.
The table does not replace uploaded files. It can contain multiple columns: choose which ones to use. Incomplete rows are skipped and counted. File names must include extensions; files not listed in the table keep their original name.
| Original name | New name from table | Match |
|---|
3. Preview and export
File extensions are protected. Edit the filename (without extension) in the right column. Duplicate or invalid names must be fixed before download.
| Original name | New filename (without extension) | Extension | Status |

Only conflicting names will change. Nothing changes until you confirm.
