Everything arrives as one ZIP with the new names applied.
A hundred files named IMG_4021 through IMG_4121 help nobody. Batch renaming — find & replace, a proper prefix, sequential numbers — is how a folder becomes an archive. This tool does it in your browser with a live preview of every change before you commit to anything.
It's also an honest demo of how RenameTo thinks: the filename is an interface. On a Mac, RenameTo goes further — renaming in Finder can compress, convert, date-stamp, and archive, not just relabel.
Free, private, no upload. Ever.
This tool runs entirely on your device. It's built by the team behind RenameTo for Mac — where the same job is just a rename in Finder.
