AI rename files: Compete with traditional tools, but smarter

If you need a fast, reliable way to rename files with a full preview, our AI rename files tool is built for you. Describe your rule in plain English - for example: "lowercase, replace spaces with hyphens, keep extensions, zero-pad numbers" - and instantly preview how we will rename files in bulk. Every step is controlled, reversible, and auditable.

Unlike traditional batch tools, the core innovation is natural language instructions. You don’t need to learn regex or write scripts to rename files consistently. We preserve extensions, normalize case and delimiters, and resolve duplicates - turning one sentence into precise steps that safely rename files across photos, invoices, design assets, and code resources.

  • Describe a rule and instantly rename files (no regex/scripts)
  • Bulk preview before applying to safely rename files
  • Keep extensions, zero-pad numbers, add prefixes/suffixes
  • Resolve duplicates and export a CSV diff after you rename files

Before

  • ✗Wrestling with complex regex patterns
  • ✗Brittle scripts that break on edge cases
  • ✗Accidentally changing file extensions
  • ✗No safe preview before applying
  • ✗Manual renaming of hundreds of files
  • ✗Inconsistent naming across projects

Now

  • Say the rule out loud in plain English
  • AI translates to consistent rename steps
  • Extensions automatically preserved
  • Full preview with conflict detection
  • Bulk rename thousands in seconds
  • Standardized naming with one click

Say the rule out loud - AI translates it to consistent, bulk rename steps you can preview and undo. No technical knowledge required.

Drag in Files or Folder

Upload your files or an entire folder. We support thousands of files at once, with all common file types and extensions.

2

Type One Sentence in Plain English

Describe your renaming rule naturally: "lowercase, spaces to hyphens, remove brackets, limit to 40 chars". No regex knowledge needed.

3

Preview Original vs. New Names

See a side-by-side comparison of all changes before applying. Verify conflicts, duplicates, and naming patterns instantly.

One-Click Recipes

Pre-configured renaming rules for common use cases. Click to apply instantly or customize to fit your needs.

Lowercase + Spaces to Hyphens

Convert all filenames to lowercase and replace spaces with hyphens for web-friendly names

lowercase; spaces → hyphens; dedupe separators

Add Prefix/Suffix

Add custom prefixes or suffixes to organize files by project, brand, or category

add prefix "brand-"; keep extension

Zero-Pad Numbers

Pad numbers with zeros (001, 002) for proper sorting in file explorers

zero-pad numbers to 3 digits; keep extension

Remove Brackets & Emojis

Clean up filenames by removing brackets, parentheses, and special characters

remove brackets; remove emojis; dedupe separators

Kebab-Case Conversion

Convert to kebab-case for consistent, SEO-friendly filenames

lowercase; spaces/underscores → hyphens; limit to 40 chars

Snake Case ↔ Camel Case

Convert between snake_case, kebab-case, and camelCase naming conventions

convert snake_case to kebab-case; lowercase

Move Date to Front

Reorder filenames to start with dates (YYYY-MM-DD) for chronological sorting

move date to beginning; format YYYY-MM-DD

Truncate Long Names

Limit filename length to 40 characters while preserving extensions

truncate to 40 characters; keep extension; add ellipsis

Chinese to Pinyin

Convert Chinese characters to pinyin (full or initials) for ASCII-safe names

Chinese → pinyin initials; kebab-case

How AI helps you safely and reliably rename files

When teams rename files at scale, small mistakes compound: a wrong regex, lost extensions, or scripts that are hard to roll back. Our approach is preview-first: see the full diff in your browser and then apply. Describe the format you want - "all lowercase, replace spaces with hyphens, zero-pad numbers to 3 digits" - and we generate an auditable plan to rename files in bulk with complete traceability.

To standardize collaboration, we ship the most common normalizations: case, delimiters, prefixes/suffixes, zero-padding, date reordering, and length trimming. Whether content comes from cameras, downloads, design assets, code, logs, or invoices, you can rename files consistently across your entire workspace. Systematically rename files and everything becomes easier to search, compare, and archive.

Compared to classic utilities, our advantage is zero learning curve and what-you-see-is-what-you-get. You don’t memorize complex patterns or worry about scripts. Say the rule, let AI preview and rename files at scale, and fine-tune until it’s perfect. That’s the next generation of how you rename files: intuitive, reliable, and efficient.
