LocalFile.io
LocalFile.io lets you bulk-rename files and run simple folder automation from the browser without sending file contents or filenames to any server. Pick a local folder, set a rename pattern, preview every proposed change, and apply the batch on your own machine.
Cloud file managers make you upload data before anything runs. LocalFile.io keeps processing local, which suits anyone handling contracts, medical records, or client deliverables who cannot expose filenames to a third party. The web app is free; you can also buy a $5 Windows .exe for one-click offline execution of a saved task.
LocalFile.io fits photographers sorting image batches, developers normalizing source file names, and archivists cleaning up large folder dumps. Tasks support lowercasing extensions, adding numeric prefixes by file size, and swapping name segments around a delimiter.
