FAQ
- Is the website 100% free for everyone?
- Yes, you can use all our file renaming features for free, with no limits, no registration, and no hidden fees.
- How does file renaming work?
- File renaming modifies the file names without changing the content. Using batch rules (prefixes, suffixes, sequence numbers, character replacements, etc.), you can quickly and efficiently organize multiple files.
- Why can the browser rename files?
- Modern browsers allow safe access to local files. With user permission, files can be batch-renamed and new files generated for download without installing any software.
- Does renaming affect file content or format?
- No. Only the file name changes. File content, size, and format remain the same.
- Which file types are supported?
- Almost all common file types, including images, videos, audio, documents, and archives. JPG, PNG, MP4, MP3, PDF, ZIP, and more can be batch renamed.
- How many files can be renamed at once?
- There is no strict limit. It depends on browser performance and device memory. On typical devices, tens to hundreds of files can usually be handled smoothly.
- Will renamed files have watermarks or extra marks?
- No. Only file names are modified. No watermarks, marks, or extra content are added.
- Why don’t files need to be uploaded to the server?
- All renaming happens locally in your browser, ensuring data privacy, ideal for sensitive or private files.
- Why might batch renaming be slower?
- Speed depends on file count, browser performance, and device. Closing unnecessary programs can improve efficiency.
- Is mobile supported?
