    Organize Your File List

    Once files are uploaded, organize them as needed:

    • Sort Files: Use the sort dropdown to organize by name, size, or date
    • Drag to Reorder: Manually arrange files by dragging them (important for numbering order)
    • Remove Files: Click the remove button on any file to exclude it
    • Check for Duplicates: Use the duplicate detection feature to find identical files

    Apply Rename Rules

    Choose your renaming strategy. You have three approaches:

    šŸ”„ Quick Templates

    Use pre-built templates for common scenarios:

    • Prefix + Counter: project_001_filename.jpg
    • Date Prefix: 2024-06-15-filename.jpg
    • Story Mode: story_01.jpg, story_02.jpg
    • Lowercase: Convert all names to lowercase
    • Clean Names: Remove symbols and spaces

    āš™ļø Individual Rules

    Build custom rules using our rule categories:

    • Add Text: Prefixes, suffixes, find/replace, insert at position
    • Numbering & Case: Sequential numbers, change text case
    • Cleanup & Trim: Remove characters, trim length, sanitize

    šŸ—ļø Action Stack (Advanced)

    Combine multiple operations in sequence:

    • Add multiple rules that execute in order
    • Drag to reorder actions

    Download Results

    Choose your preferred download method:

    • Individual Download: Files download one by one with their new names
    • ZIP Archive: All files packaged into a single ZIP file for easy transfer

    Both methods preserve your original files - only the downloaded copies have the new names.

    Pro Tip: Use ZIP download when renaming large numbers of files for easier management and sharing.

    Limitations & System Requirements

    While our bulk filename renamer is powerful and versatile, there are some limitations and system requirements you should be aware of for optimal performance.

    Browser Requirements

    Supported Browsers

    • Chrome 80+
    • Firefox 75+
    • Safari 13+
    • Edge 80+

    Unsupported Browsers

    • Internet Explorer (all versions)
    • Older mobile browsers
    • Text-only browsers

    File Size & Quantity

    Recommended Maximum
    200-300 files per session
    Optimal performance for most systems
    Absolute Maximum
    ~1000 files
    Browser memory dependent
    Individual File Size
    No specific limit
    Limited by available RAM
    Total Session Size
    ~2GB total
    Browser memory constraints

    Technical Limitations

    Memory Intensive

    All files are loaded into browser memory. Very large batches may slow down or crash the browser.

    No System File Access

    Cannot rename files outside the browser session. Original files remain unchanged on your system.

    No Folder Structure Preservation

    All files are processed as a flat list. Subfolder structures are not maintained in the output.

    Session-Based Only

    No save/load functionality. All work must be completed in a single browser session.

    Feature Limitations

    Metadata Extraction

    Partial Support
    • EXIF Data: Basic date and resolution only
    • ID3 Tags: Title and artist for MP3 files only
    • No Support: Custom metadata, PDF properties, document metadata

    File Type Handling

    Full Support

    All file types supported for renaming, but preview only available for images.

    Regular Expressions

    Limited Support

    Basic pattern matching only. No advanced regex features like lookaheads or backreferences.

    šŸ’” Performance Optimization Tips

    Batch Large Collections

    Process very large file collections in multiple batches of 200-300 files each.

    Close Other Tabs

    Close unnecessary browser tabs to free up memory for better performance.

    Use Simple Rules First

    Apply complex rules in separate steps rather than all at once in the action stack.

    Download Frequently

    Download and clear the file list periodically when working with large batches.

    šŸ› ļø Common Limitations & Workarounds

    Browser crashes with large files
    Process files in smaller batches or use a desktop application for very large collections
    Need to preserve folder structure
    Process folders individually and manually recreate the structure after renaming
    Advanced metadata needed for naming
    Use specialized software for complex metadata-based renaming scenarios
    Regular browser refreshes lose work
    Download renamed files frequently and avoid refreshing the page during long sessions

    šŸ’» Recommended System Specifications

    Minimum Requirements

    RAM: 4GB
    Browser: Chrome 80+ / Firefox 75+
    Files: Up to 100 files

    Recommended for Best Experience

    RAM: 8GB+
    Browser: Latest Chrome/Firefox
    Files: 200-300 files per batch

    Power User Setup

    RAM: 16GB+
    Browser: Chrome with hardware acceleration
    Files: 500+ files (with caution)

    Advanced Usage Tips & Techniques

    šŸ”„ Mastering the Action Stack

    Complex Renaming Workflow

    Combine multiple actions for sophisticated renaming:

    replace Replace " " with "_"
    case Convert to lowercase
    prefix Add "project_" prefix
    number Add sequential numbers

    Result: "my file.jpg" → "project_my_file_001.jpg"

    šŸŽÆ Smart Numbering Strategies

    Custom Numbering Patterns

    • Start from specific number: Use 100 instead of 1 for continuation
    • Different padding: 001 vs 0001 based on total file count
    • Position control: Number before or after filename

    Metadata-Based Numbering

    Sort by date taken (EXIF) before numbering to create chronological sequences for photos.

    šŸ”§ Power User Shortcuts

    Efficient Workflows

    • Use templates as starting points, then customize
    • Save complex action stacks for recurring tasks
    • Combine duplicate detection with renaming in one session
    • Use find/replace with empty "replace" field to delete text

    Common Use Case Templates

    Photo Gallery Organization

    Goal: vacation_001.jpg, vacation_002.jpg...

    1. Upload all photos
    2. Sort by date taken (if EXIF data available)
    3. Apply template: Prefix + Counter
    4. Set prefix to "vacation_"
    5. Set padding to 3 digits
    6. Preview and download

    Document Version Control

    Goal: report_v2.1_final.docx, budget_Q3_2024.xlsx

    1. Upload document files
    2. Use Find & Replace to update version numbers
    3. Add date suffixes using Insert Text
    4. Apply Title Case for consistency
    5. Remove any temporary prefixes (like "draft_")

    Music Library Standardization

    Goal: Artist - Song Title.mp3

    1. Upload music files
    2. Use multiple Find & Replace actions to fix common patterns
    3. Apply consistent spacing around dashes
    4. Use Title Case for song titles
    5. Remove unwanted characters like underscores

    Troubleshooting Common Issues

    āŒ Files not uploading

    Solution: Check file size limits and browser compatibility. Try refreshing the page.

    šŸ”¢ Numbering not in correct order

    Solution: Sort or drag files into the desired order before applying numbering rules.

    šŸ“› Special characters in filenames

    Solution: Use the "Remove symbols" or "Sanitize" options to clean filenames.

    šŸ”„ Actions not applying correctly

    Solution: Check action stack order and ensure find/replace text matches exactly.

    šŸ“„ Download not working

    Solution: Check browser pop-up settings and ensure you have storage space.

    ⚔ Performance with large batches

    Solution: Process files in smaller batches of 100-200 files for optimal performance.
