Processing order Find & Replace → Clean Filename → Numbering → Prefix / Suffix

Frequently Asked Questions

  1. 01

    What types of files can I rename?

    You can rename images, documents, PDFs, spreadsheets, videos, and other common file types supported by your browser.

  2. 02

    My files are large and there are a lot of them. Do I need to upload them?

    No. You don't need to upload your files, even if you are renaming a large number of files. The tool works directly in your browser.

  3. 03

    Can I use the bulk file renamer on my phone?

    Yes, you can use it on supported mobile browsers. Some file-management features may depend on your browser and device.

  4. 04

    Can I rename files using more than one option at the same time?

    Yes. You can combine different renaming options to create the filename format you need.

  5. 05

    Can I rename hundreds of files at once?

    Yes. You can rename a large number of files in a folder at once, instead of changing each filename individually.

  6. 06

    Do I need to download the renamed files again from my browser?

    No. The tool is designed to rename your files on your device rather than upload them to a server and send them back as downloads.

  7. 07

    Can this tool access, analyze, or steal my files or other data from my device?

    No. CleanFiles.click does not upload, store, or analyze your files. The tool only uses the files you select for the renaming process, and your files remain on your device. It cannot access unrelated files or personal data on your computer or phone.
