What is Bulk Image Renamer?

This bulk rename files tool lets you rename multiple photos at once using a consistent naming pattern instead of renaming each file by hand. It works well as a sequential file renamer online for organizing event photos, product images, or project files with numbered or custom names. It's a lightweight alternative to OS-level batch renaming tools when you want a quick, no-install browser option.

How It Works

Each file you upload is read in your browser, and a new filename is generated based on the pattern you define, such as a prefix plus a sequential number or a custom text string. The renaming logic runs entirely in JavaScript within your browser tab, applying your chosen naming scheme consistently across the whole batch in the order you set. The renamed files are then packaged together for download with their new names applied.

Is It Safe to Use?

Because renaming happens locally in your browser, your image files are never uploaded to a server just to change their filenames. This keeps personal photos, business assets, or project files completely private throughout the renaming process. No file content or names are logged or stored outside your own session.

How to Use Bulk Image Renamer (Step-by-Step Guide)

  1. Drag and drop multiple photos at once into the upload area
  2. Choose a naming pattern, such as a custom prefix followed by sequential numbers
  3. Set the starting number and numbering format if using sequential naming
  4. Reorder files in the queue if the renaming order matters to you
  5. Preview the new filenames before processing to confirm they look correct
  6. Download all renamed images together as a ZIP file

Frequently Asked Questions

Can I rename multiple photos at once with custom text plus numbers?
Yes, you can set a custom prefix or suffix combined with sequential numbering, like 'vacation-001.jpg', 'vacation-002.jpg', and so on.
Is this a true sequential file renamer online, or does it just add random names?
It's sequential by design, assigning numbers in order based on the sequence you set, which is ideal for organizing batches of photos.
Will renaming files change the image quality or format?
No, only the filename changes; the image data, resolution, and format remain exactly the same.
Can I control the order the files get renamed in?
Yes, you can typically reorder the upload queue before processing so the sequential numbers match your intended order.
Does this work for file types other than images?
This tool is built specifically for image files; non-image files aren't supported for renaming here.
How many files can I bulk rename at once?
You can queue up a large batch of files in one session, limited mainly by your browser's memory rather than a fixed file count.
Why not just use my operating system's built-in batch rename feature?
This browser tool is a quick, no-install option when you want a simple renaming pattern without digging into OS-specific batch rename settings.
Can I add leading zeros to the sequential numbers, like 001 instead of 1?
Yes, the numbering format typically supports leading zeros so your filenames sort correctly in file explorers.
