What Is Batch Renaming?

Batch renaming is the process of changing the filenames of multiple files at once using a systematic rule or pattern. Instead of manually clicking "Rename" on every single photo, you can apply a consistent format like "Vacation_2024_001.jpg" to an entire folder instantly.

Common Use Cases

Photographers

Convert cryptic camera filenames like "DSC_8943.jpg" into meaningful names like "Wedding_Shoot_001.jpg" for clients.

E-commerce

Standardize product images with SKUs (e.g., "shoe-red-01.jpg") for better inventory management and SEO.

SEO Optimization

Search engines prefer descriptive filenames. Renaming "Img1.jpg" to "hiking-boots-waterproof.jpg" can improve visibility.

Digital Archiving

Organize scanned documents or old photos by date and category for easier retrieval.

  4. Preview: Check the live table to ensure the new names are exactly what you want.
  5. Download: Click "Download ZIP" to get your renamed files.

Frequently Asked Questions

Can I rename JPG and PNG together?▼
Yes! You can mix and match any supported image formats (JPG, PNG, WEBP, GIF, SVG) in a single batch. Our tool preserves the correct file extension for each image.
Are my images uploaded?▼
No. All renaming happens locally in your web browser. Your files are never sent to our servers, ensuring complete privacy.
Will this change image quality?▼
Not at all. We only change the filename. The image data itself is not re-encoded or modified, so the quality remains 100% original.
Can I keep original file extensions?▼
Yes, by default we preserve the original extension (e.g., .jpg, .png). You can disable this if you have a specific need, but it's recommended to keep it.
Can I rename hundreds of images?▼
Yes. Since the processing is lightweight and happens on your device, you can rename hundreds of files in seconds without hitting server limits.
Why do my files sort incorrectly without padding?▼
Computers often sort alphabetically, meaning 'image-10' comes before 'image-2'. Using padding (e.g., 'image-002', 'image-010') ensures files stay in the correct numerical order.
