How many photos can I batch rename at once?

You can batch rename hundreds of photos in one go. The only limit is the memory available on your device since everything happens right in your browser.

Will this tool change the original files on my computer?

No. Browsers cannot overwrite your local files. The tool creates a ZIP file containing your newly renamed images for you to download.

Can I organize photos by the date they were taken?

Yes. The tool looks at the last modified date of each file and sorts them chronologically. This keeps your photos in the correct order.

What will the new filenames look like?

Your files get the prefix you choose followed by a sequential number. For example, BeachTrip_001.jpg, BeachTrip_002.jpg, and so forth.

What is a Bulk Image Renamer?

A bulk image renamer helps you take a messy folder of photos with random names like IMG_4821.jpg or WA0043.jpeg and changes them to a clean, sequential format.

This tool works entirely inside your browser. You just drop in your images, choose a prefix, decide how to sort them, and download a ZIP file of the renamed images in seconds. There is no software to install, no uploading, and no file size limits.

How to Use

Drop your images: Drag and drop all the photos you want to rename into the upload area.
Choose a sort order: Sort by filename, file size, or last modified date. Sorting by date is great for keeping photos chronological.
Set a prefix: Type a base name for the batch, such as Holiday_Rome or Product_Blue.
Download the ZIP: The tool creates sequential filenames like Holiday_Rome_001.jpg and bundles them into a single ZIP file for easy downloading.

Use Cases

Travel photography: Merge photos from your phone and your camera into one folder with a consistent naming scheme.
E-commerce product photos: Standardize dozens of product images before adding them to your online store. Clean names make managing your catalog much easier.
Event photography: Rename all photos from a wedding or party so they sort perfectly chronologically for your clients.
Stock photography: Prepare large batches of images with descriptive filenames before uploading them to stock websites.
Archiving: Organize messy photo dumps from older devices into one cleanly named archive.

Why Use This

Most batch renaming software requires downloading and installing an application on your computer. Many online options force you to upload your photos to their servers. This is slow and creates privacy risks for personal or client photos.

This tool solves that problem. It processes everything locally on your device using your browser. Your photos go straight into a ZIP file on your hard drive, meaning nothing is ever transmitted over the internet.

Sorting Options Explained

By filename: Sorts alphabetically. This is useful if your current filenames already have a logical order.
By file size: Sorts from smallest to largest file.
By last modified date: Sorts chronologically based on when each file was last changed. This is the best way to sort photos in the order you captured them.
