Rename multiple files at once with various patterns
Bulk file renaming is the process of renaming multiple files at once using patterns, rules, or find-and-replace operations. Instead of renaming files one by one (which can take hours for large collections), bulk file renaming allows you to rename hundreds or thousands of files in seconds. This is essential for organizing files, standardizing naming conventions, adding sequential numbers, removing unwanted text, and managing large file collections.
Bulk file renaming is particularly important for photographers organizing image collections, content creators managing media files, developers organizing project files, and anyone working with large numbers of files. Manual renaming of hundreds or thousands of files is time-consuming, error-prone, and impractical. Bulk file renaming automates this process, ensuring consistent naming conventions and saving significant time. The bulk file renamer makes this process simple and accessible, allowing anyone to rename large batches of files quickly and efficiently.
Different renaming modes serve different purposes: Sequential numbering adds numbers to files (001, 002, 003), perfect for organizing photos or documents, Find & Replace finds specific text and replaces it with new text, ideal for fixing naming issues or standardizing formats, Prefix/Suffix adds text to the beginning or end of filenames, great for adding identifiers or categories, and Custom patterns use placeholders like {name}, {n}, {date}, {time} for maximum flexibility. Understanding these modes helps you choose the right approach for your file organization needs.
Research from file management and organization communities shows that bulk file renaming is one of the most requested features for file organization workflows. Tools and platforms like Bulk Rename Utility, Advanced Renamer, and file managers emphasize bulk renaming capabilities because of their critical importance in file organization and management. The bulk file renamer ensures you can organize large file collections quickly and efficiently.
Bulk file renaming is particularly important for maintaining organized file collections, standardizing naming conventions across teams, preparing files for distribution, and managing large media libraries. Whether you're organizing photos from a vacation, renaming downloaded files, standardizing project files, or managing content libraries, bulk file renaming saves time and ensures consistency. The bulk file renamer makes this process simple and accessible, allowing anyone to rename large batches of files quickly and efficiently.
Bulk file renaming is essential for organizing large file collections. Our tool provides a simple, efficient way to rename multiple files at once with complete privacy and support for various renaming patterns.
Four renaming modes for different use cases: Sequential (add numbers), Find & Replace (fix naming issues), Prefix/Suffix (add identifiers), and Custom (use patterns). Each mode is designed for specific scenarios, making it easy to choose the right approach for your file organization needs. Sequential is perfect for numbered files, Find & Replace is ideal for fixing naming issues, Prefix/Suffix is great for adding identifiers, and Custom offers maximum flexibility.
See exactly how files will be renamed before processing. The preview shows a side-by-side comparison of original names and new names, allowing you to verify the renaming pattern works correctly. Review the preview carefully to ensure the renaming pattern works as expected. If the preview doesn't look right, adjust the settings and preview again. This prevents mistakes and ensures you get the results you want.
All file renaming happens entirely in your browser using JavaScript. Your files are never uploaded to any server, stored, or tracked. The renaming process, preview generation, and ZIP file creation all happen locally on your device. This ensures complete privacy and security, allowing you to rename sensitive files without any data collection or privacy concerns. Perfect for confidential documents, personal files, and sensitive content.
Rename hundreds or thousands of files in seconds. The tool processes files efficiently, applying renaming patterns to all files in a batch. This saves significant time compared to manual renaming, which can take hours for large collections. Whether you're organizing photos, renaming downloaded files, or standardizing project files, bulk renaming makes the process quick and efficient.
Use custom patterns with placeholders like {name}, {n}, {date}, {time}, {timestamp}, {ext} for maximum flexibility. Create complex naming schemes that combine multiple elements. For example, 'photo-{n}-{date}.{ext}' creates names like 'photo-1-2024-01-15.jpg'. This provides maximum flexibility for creating custom naming schemes that match your specific needs and preferences.
Download all renamed files as a ZIP archive for easy organization and distribution. The ZIP file contains all files with their new names, making it easy to extract and use the renamed files. This is perfect for sharing renamed files, organizing downloads, and managing file collections. The ZIP download preserves file structure and makes it easy to work with renamed files.

Renaming multiple files is straightforward with our tool. Follow these steps to rename large batches of files quickly and efficiently:
Click 'Upload Files' and select multiple files you want to rename. You can select files of any type (images, documents, videos, etc.) and mix different file types in a single batch. Hold Ctrl (Windows) or Cmd (Mac) to select multiple files, or use Shift to select a range. The tool will display all uploaded files with their original names. You can remove individual files if needed.
Select a renaming mode: Sequential (add numbers like 001, 002), Find & Replace (find and replace text), Prefix/Suffix (add text to beginning/end), or Custom (use patterns). Each mode is designed for different use cases. Sequential is perfect for numbered files, Find & Replace is ideal for fixing naming issues, Prefix/Suffix is great for adding identifiers, and Custom offers maximum flexibility with pattern-based renaming.
Configure the options for your chosen mode. For Sequential: set starting number and format (use {n} for the number). For Find & Replace: enter text to find and replacement text, choose case sensitivity. For Prefix/Suffix: enter prefix and/or suffix text. For Custom: enter pattern using {name}, {n}, {date}, {time}, {timestamp}, {ext}. The tool shows examples and descriptions for each option.
Click 'Preview Rename' to see how files will be renamed. The preview shows a side-by-side comparison of original names and new names. Review the preview carefully to ensure the renaming pattern works correctly. If the preview doesn't look right, adjust the settings and preview again. The preview helps you catch issues before processing and ensures you get the results you want.
Once you're satisfied with the preview, click 'Download Renamed Files' to download a ZIP file containing all files with their new names. The ZIP file preserves the original files with their new names. Extract the ZIP file to access your renamed files. All processing happens in your browser, ensuring complete privacy. Use the renamed files for your intended purpose.
Following best practices ensures you get the best results from bulk file renaming. Here are essential guidelines for renaming multiple files:
Always use the preview feature to see how files will be renamed before downloading. The preview shows a side-by-side comparison of original names and new names, allowing you to verify the renaming pattern works correctly. Review the preview carefully to ensure the renaming pattern works as expected. If the preview doesn't look right, adjust the settings and preview again. This prevents mistakes and ensures you get the results you want.
Select the renaming mode that best fits your use case. Sequential is perfect for numbered files (photos, documents), Find & Replace is ideal for fixing naming issues or standardizing formats, Prefix/Suffix is great for adding identifiers or categories, and Custom offers maximum flexibility for complex naming schemes. Understanding each mode helps you choose the right approach for your file organization needs.
When trying a new renaming pattern, test it with a small batch of files first. Upload a few files, configure the renaming options, preview the results, and verify they look correct. Once you're confident the pattern works, apply it to larger batches. This helps you catch issues early and ensures the renaming pattern works as expected before processing large file collections.
Create descriptive naming patterns that make files easy to identify and organize. Use meaningful prefixes, suffixes, and patterns that convey information about the files. For example, 'photo-{n}-vacation-2024.jpg' is more descriptive than 'file{n}.jpg'. Descriptive patterns make it easier to find and organize files later, improving file management and organization.
The tool preserves file extensions by default, ensuring files remain usable after renaming. In custom patterns, use {ext} to include the extension explicitly. Avoid removing or modifying extensions unless necessary, as this can make files unusable. Preserving extensions ensures files open correctly with their associated applications and maintain compatibility.
Avoid using invalid filename characters like /, \, :, *, ?, ", <, >, | in your renaming patterns. These characters are not allowed in filenames on most operating systems and will cause errors. The tool may not prevent all invalid characters, so be careful when creating custom patterns. Stick to alphanumeric characters, hyphens, underscores, and spaces for maximum compatibility.

The tool handles mixed file types in a single batch, making it perfect for organizing diverse file collections.
The maximum number of files depends on your browser's memory and performance. Most modern browsers can handle hundreds or even thousands of files in a single batch. Very large batches (over 1000 files) may cause performance issues or browser slowdowns. If you encounter issues with large batches, try processing files in smaller groups. The tool processes files efficiently, but browser memory limits apply for very large batches.
Yes, the tool includes a preview feature that shows how files will be renamed before you download them. Click 'Preview Rename' to see a side-by-side comparison of original names and new names. This allows you to verify the renaming pattern works correctly and catch any issues before processing. The preview shows all files and their new names, making it easy to review and adjust settings if needed.
Custom mode supports several patterns: {name} for the original filename (without extension), {ext} for the file extension, {n} for sequential number, {date} for current date (YYYY-MM-DD), {time} for current time (HH-MM-SS), and {timestamp} for Unix timestamp. You can combine these patterns with custom text. For example, 'photo-{n}-{date}.{ext}' would create names like 'photo-1-2024-01-15.jpg'. This provides maximum flexibility for creating custom naming schemes.
