How many files can I rename at once?

You can rename as many files as your browser can handle in memory. In practice, this means hundreds of files work smoothly. For very large batches of thousands of files, we recommend processing them in smaller groups for the best performance.

Can I combine multiple rename rules?

Yes, you can apply multiple rename strategies in sequence. For example, you can first add a prefix and then apply sequential numbering. The preview updates in real-time as you add or modify rules, so you can see the combined effect before applying.

Does the tool change the file content?

No, the tool only changes the file name. The actual content of your files remains completely untouched. The renamed files are identical to the originals in every way except the name.

Can I undo the rename operation?

Since the tool downloads the renamed files as new files rather than modifying originals, your original files remain unchanged on your device. You can always revert by using the original files. The preview feature also helps you verify names before applying.

What numbering formats are supported?

The tool supports sequential numbering with customizable leading zeros, starting number, and increment step. For example, you can create names like file-001, file-002, or item-10, item-20. You can also place the number anywhere in the file name.

Can I use regular expressions for find and replace?

Yes, the find and replace mode supports regular expressions for advanced pattern matching. This lets you perform complex replacements like removing all numbers from file names or replacing specific patterns with dynamic content.

Are my files uploaded to a server during renaming?

No, all processing happens locally in your browser. Your files are read, renamed, and packaged for download entirely on your device. No data is transmitted to any server, ensuring complete privacy.
