I needed to rename hundreds of .jpeg files to .jpg across nested folders. Softaken File Extension Changer did it in a few steps with From→To mapping and subfolders included. File content stayed the same — only the extension changed. Perfect freeware for Windows.

Used the “Create a copy of file with new extension” option so my originals stayed untouched while I batch-changed .txt to .csv. Simple UI,free forever,and no hassle renaming multiple extensions at once.
