How to Rename Files in Bulk Online
Add files, choose rename rules, review every new filename, and export renamed files as single downloads or a ZIP.
Select your files
Drag files into the uploader, or click to choose them from your device. Start with one file or a larger bulk rename job.
Choose rename rules
Tell the tool how the new names should look: add a prefix or suffix, type a manual date, run find and replace, change case, clean names, or add sequence numbers.
Review live preview
Check the renamed results before anything is downloaded. You can spot conflicts, confirm filenames, and undo or reset changes.
Download renamed files
When the preview looks right, download renamed files one by one or export the full bulk rename result as a ZIP package.
Filename Rules You Can Combine
Build a practical workflow to bulk rename files with rules you can preview before downloading.
Add prefixes or suffixes
Add project names, labels, manual dates, or status tags to many filenames at once.
Find and replace filename text
Replace repeated words, remove unwanted text, or clean exported filenames across the whole batch.
Add sequential numbers
Number files in preview order, place the number before or after the name, and use zero padding like 001, 002, and 003.
Change filename case
Convert filenames to uppercase, lowercase, or title case for a more consistent batch.
Clean messy names
Remove download numbers, duplicate markers, special characters, and extra separators.
Undo before downloading
Preview every renamed file and undo or reset changes before exporting the result.
When You Need to Rename Files in Bulk
Use this bulk file renamer when filenames need to be clearer, easier to sort, or ready for upload before you share, archive, or publish a batch.
Prepare image uploads
Turn camera names, AI exports, or downloaded images into readable filenames before compressing, resizing, converting, publishing, or sharing.
Clean messy downloads
Make saved files easier to scan by removing copy markers, download numbers, special characters, and extra spaces.
Standardize project assets
Give design assets, documents, exports, or archives consistent labels and sequence numbers so related files stay easy to sort.
Bulk Rename Files FAQ
Answers about privacy, original files, file types, how to rename files in bulk, duplicate names, ZIP downloads, and current limits.
Can I rename files online without uploading?
Yes. Files are handled locally in your browser. The tool creates renamed downloads on your device without uploading your selected files to a server.
Will this rename my original files on my computer?
No. This tool does not rename your original files in place. It downloads renamed copies, so the files already on your computer stay unchanged.
Does renaming change the file content or file type?
No. Only the output filename changes. The image, document, audio, video, or other file content is not edited or converted, and the existing extension is preserved and normalized when possible.
Which file types can I rename?
You can rename common files such as images, PDFs, documents, archives, audio, and video files. The tool works with filenames; it is not limited to image files.
Can I rename multiple files at once?
Yes. Select multiple files, apply rules like prefix, suffix, find and replace, case conversion, cleanup, or sequential numbering, then review the live preview before downloading renamed copies.
What happens if two files get the same name?
The preview automatically keeps output names unique by adding a numeric suffix such as -2 before download.
Can I download all renamed files together?
Yes. For a batch, you can download files individually or export all renamed copies in one ZIP package.
Does find and replace support regular expressions?
No. Find and replace uses plain text matching in the current version. Use it for repeated words, labels, spaces, or simple filename fragments.
Can I upload folders or change file extensions?
No. The current version supports selecting files, not a dedicated folder workflow. Rename rules apply to the filename before the extension, so this tool does not convert files or intentionally change their extensions.
Ready for Another Batch?
Go back to the uploader and run another group of files through the same rename workflow.
