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?
Yes. Most modern mobile browsers can rename files, but large batches may be slower than on a PC.
Is renaming faster on a computer?
Yes. PCs usually have better performance and multi-file handling, making large batch renaming faster and more stable.
