About

A free online file renamer

renameafile is a free online file renamer. Instead of right-clicking and editing names one at a time, you open a file in your browser, type the name you want, and download a clean copy. The original file is left untouched, and the extension is kept unless you choose to change it. Everything runs locally, so your files are never uploaded, and it works the same for a private document as for a quick photo rename.

There is nothing to install and no account to create. It handles a single file or a whole batch, shows the name and extension as separate boxes, and works with images, documents, audio, video, archives and more.

Rename files on any device

Because renameafile runs entirely in the browser, it works on Windows, macOS, Linux, Android and iPhone, anywhere with a modern browser. There is no separate app to download for each platform. Open the page, rename your files, and the renamed copies land in your usual downloads folder.

FAQ

Questions

How do I rename a file?

Choose the file, type the new name in the box, and click Download. The renamed copy is saved to your downloads and the extension is kept automatically, so you can't break the file.

Can I rename a file without changing its extension?

Yes, that is the default. The name and extension are separate boxes, so editing the name leaves the extension alone. You can also change the extension if you want to.

Are my files uploaded anywhere?

No. Everything runs in your browser: files are read, renamed, and saved back to your device. Nothing is sent to a server.

Is renameafile safe?

Yes. Files are processed locally in your browser and are never uploaded, so nothing leaves your device. Your originals are kept too, so you only ever download renamed copies.

Does it work with every file type?

Yes. By default only the name changes, so the file's contents are never altered. Images, PDFs, archives, audio and video all work the same way.

Can I rename several files at once?

Yes. Add multiple files, give each one a new name, and download them together.

Can I rename files on my phone?

Yes. It works in mobile browsers on iPhone and Android the same way it does on a computer. Choose a file, type a new name, and download the renamed copy.

Can I undo a rename?

Originals are never modified. Renamed copies are downloaded as new files, so you can keep or delete the originals as you like.

Is the file renamer free?

Yes. No account, no limits, no upload.

Rename any file. In seconds.
