About the Advanced Bulk Rename Tool

Our Advanced Bulk Rename Tool is the most powerful file renaming utility on File Rename Online. It combines three renaming methods — pattern-based renaming, find & replace, and prefix/suffix addition — into a single tool with full preview and ZIP download. Whether you need to rename five files or five thousand, this tool handles it instantly.

Everything runs entirely inside your browser. Your files are never uploaded to any server, making this tool ideal for sensitive documents, confidential client work, and proprietary data. There are no file type restrictions and no usage limits.

Three Powerful Renaming Modes

Pattern Mode replaces all file names with a base name plus sequential numbers, with configurable padding from 2 to 5 digits. Find & Replace Mode searches for specific text within existing file names and replaces it. Prefix/Suffix Mode adds text before or after the existing file name without changing the original.

Advanced Numbering Formats

The numbering system supports five padding levels: no padding, 2-digit, 3-digit, 4-digit, and 5-digit. This ensures files sort correctly in every file manager and operating system. You can start numbering from any number, making it easy to continue where a previous batch ended.

Frequently Asked Questions

What is the difference between the three modes?

Pattern replaces all names with a base name + number. Find & Replace modifies specific text within existing names. Prefix/Suffix adds text before or after names without changing the original.

Can I combine multiple modes?

The tool applies one mode at a time for clarity. However, you can download the renamed files and then re-upload them to apply a second transformation.

What numbering format should I use?

Use 3-digit padding (001, 002) for batches under 1,000 files. Use 4-digit (0001) for larger collections. Padding ensures files sort correctly.

Does find & replace work on extensions?

Find & replace operates only on the file name, not the extension. Extensions are handled separately by the lowercase option to prevent accidentally breaking file associations.

Are my files uploaded to a server?

Absolutely not. Everything runs inside your browser using JavaScript. Files are read, renamed and zipped on your own device.

Is there a file count or size limit?

No limit on the number of files. Individual files can be up to 100MB each. The tool handles large batches smoothly in your browser.
