Rename a batch of files using a pattern, then download as a ZIP. 100% free, no sign-up — your file never leaves this browser tab.
Batch Rename Files lets you batch rename files entirely inside your browser, with no software to install and no account to create. Like every tool on Techsinghge Smart Tools, it's built around cleaning up and shrinking a file so it's faster to send, store, and open, and it works the same way whether you're on a laptop, a Chromebook, or a phone.
Under the hood, Batch Rename Files takes a batch of files and hands back the same files renamed using a pattern, downloaded as a ZIP. Your file is loaded directly into this page's memory using JavaScript — nothing is transmitted to a server, which means there's no upload wait, no file-size cap tied to a paid plan, and no copy of your document left sitting on someone else's storage once you're done.
Renaming a folder of scanned pages into a consistent sequence is one of the most common reasons people reach for this tool, but it works just as well for standardizing product photo filenames before uploading to a store. If you need a related step before or after this one, check the related tools further down the page — every tool on this site is designed to slot into the same drag-and-drop workflow.
No installs, no accounts — just your browser doing the work.

Because Batch Rename Files runs locally, teams handling sensitive paperwork — legal, HR, healthcare admin, finance — can use it without the compliance questions that come with uploading documents to a third-party server.
