Batch Rename Files on Mac: Complete Guide (2026)
TL;DR
- The built-in Finder tool on macOS can replace text, add text or format file names, but its options are limited and require manual steps [support.apple.com]. You can undo changes with Command-Z [macmost.com].
- Third-party renamers like ForkLift combine multiple rules (change case, replace text, add date) yet still lack AI context and require careful setup [blog.binarynights.com].
- NameQuick is a macOS-only app that uses AI to understand your files. Smart Rename and customizable Presets generate descriptive names (e.g., IMG_4823.jpg → Wedding_Ceremony_Garden_Sunset.jpg) using OCR and text extraction, while preserving extensions and safely handling invalid output.
- Watch Folders, menu-bar access and a global shortcut mean NameQuick can automate batch renaming and filing the moment new items appear, without interrupting your workflow.
- With Templates, Custom Prompts and Rules, you can build pattern-based naming schemes, pull EXIF metadata, apply Finder tags and move files into structured folders -- turning chaotic downloads and photo archives into organised projects.
Introduction
If you're a freelancer, photographer, researcher or business owner who uses a Mac, you've probably stared at a folder full of cryptically named files. Perhaps your Downloads folder is overflowing with download(3).pdf and IMG_4823.jpg, or your client deliverables are scattered as "Final_v2_FINAL.docx" duplicates. Batch renaming isn't just a neat trick; it's a way of enforcing naming conventions, improving searchability and eliminating duplicates. Modern macOS provides a built-in option to rename multiple files at once, but its three-rule system (replace, add or format) can feel restrictive and time consuming [support.apple.com]. Third-party rename utilities offer more flexibility, yet they still operate on simple string manipulations and require manual intervention.
This article explores why batch renaming files on macOS matters, what the Finder and other tools can (and can't) do, and how NameQuick reimagines the process through AI, automation and smart templates.
Why Mac users need smarter batch renaming
Every photo shoot, research project or product launch generates a batch of files. Without a clear naming convention, you end up with cluttered file names, duplicates and inconsistent prefixes or suffixes. For example, multiple cameras might output names like DSC_0001.JPG or IMG_4823.jpg, while PDF downloads appear as download(3).pdf. Searching for the right asset becomes tedious, especially when working with hundreds or thousands of items. Consistent naming also matters when collaborating across devices: many clients or collaborators use a mix of iPhone and Android devices, so adopting a clear "YYYY-MM-DD_Description" scheme (with lower case or uppercase as needed) improves cross-platform compatibility.
Misnamed files introduce errors, too. Apple's support documentation cautions against renaming file extensions or system folders because changing the extension can make a file unusable [support.apple.com]. Photographers often want to embed the date taken or camera model into names, while researchers may need to capture details from scanned PDFs. Doing this by hand or with Finder's limited rename utility is error prone and time consuming.
The pain is amplified by volume: selecting each item, right-clicking and choosing Rename works for a handful of selected files, but when you have hundreds of JPGs to sort into client folders, manual renaming disrupts your workflow. Even command-line loops that use mv to rename patterns require scripting knowledge and offer no preview. That's why more sophisticated automation is needed.
How macOS Finder handles batch renaming
The simplest way to batch rename files on a Mac is built into Finder. Apple's guide explains that you must first select the items, Control-click (or right-click), choose Rename, and then choose a rename mode [support.apple.com]. There are three modes:
Replace Text -- You enter the text you want to remove and the text to replace it with. For example, replacing "Draft" with "Final" will change every instance in the selected file names [support.apple.com].
Add Text -- You supply text to insert and choose whether to add it before or after the current name [support.apple.com]. This is handy for adding a project prefix or suffix.
Format -- You define a new name and add an index, counter or date before or after it [support.apple.com]. The index uses simple numbers (1, 2, 3), the counter adds leading zeros (0001, 0002) and the date inserts the current date and time.
Once configured, you click Rename to apply the changes [support.apple.com]. If you make a mistake, Command-Z allows you to undo the entire batch [macmost.com]. Finder also shows a preview of one new name before confirming [blog.binarynights.com].
Finder's tool helps with straightforward tasks like replacing draft with final, adding a prefix such as "Q1" or changing a run of JPG files from Vacation_001.jpg to Vacation 1.jpg. However, its limitations become clear when you need more complex logic. According to an analysis of blog posts and tutorials, Finder only supports these three basic rules; you cannot combine multiple replacements or use advanced regular expressions, and the Name and Date option inserts the current timestamp rather than the actual creation date [blog.binarynights.com]. To rename by EXIF date or camera model, you must use third-party solutions or write a script. Even adding a different name format, like YYYY-MM-DD_Project_Photo##, requires manual entry and is not reusable.
Apps like ForkLift extend Finder's capabilities by allowing multiple rename rules, changing case and saving presets [blog.binarynights.com]. Yet they still rely on manual string operations: you must choose from modules like change case, replace text or add date, then define rule order [blog.binarynights.com]. While helpful for power users, these rename utilities lack context awareness -- there's no way to extract a descriptive title from a PDF, detect people in a photo or understand the document content. They also require you to open a separate app for each bulk rename session.
Meet NameQuick: AI-powered renaming and organization for macOS
NameQuick is a macOS-only application designed to make renaming and organising files as effortless as typing a sentence. It's an AI-powered rename utility that goes beyond simple replacements by understanding the content of your files. Where Finder merely renames strings, NameQuick reads documents, performs OCR on images or PDF files, and parses metadata so your file names are meaningful.
Smart Rename
In Smart Rename mode, you drag files into NameQuick (or use a global shortcut, menu-bar icon or Finder selection) and the app suggests descriptive names. For example, the app can rename IMG_4823.jpg to Wedding_Ceremony_Garden_Sunset.jpg or transform download(3).pdf into 2025-01-15_Project_Update.pdf. It does this by extracting text, dates and context from images or Office documents using OCR and text extraction. Smart Rename uses your chosen AI provider -- Gemini, OpenAI, Claude (Anthropic) or a local Ollama model -- and there's no silent switching, so you always know which engine processes your data.
Presets: Templates and Custom Prompts
NameQuick offers two kinds of presets. Templates are visual patterns built with drag-and-drop field chips. Each template can combine up to eight extraction types: text, date, regex pattern, literal strings, counters, conditional values, computed values or the original file name. You can insert over sixteen built-in placeholders (for example {date:yyyy-MM-dd}, {year}, {month}, {original}, {extension}, {parent}, {size}, {dimensions}, {counter}) and build fallback chains so a second extraction runs if the first fails. Templates also support unified pre- and post-extraction rules, and you can test them in real time with actual files. This approach is perfect for creating consistent naming conventions, such as 2026-02-25_ProjectName_CameraModel_001 where the date comes from metadata and the counter starts from a chosen number.
If you prefer natural language, Custom Prompts let you describe how to rename files in free-form text. You might write, "Name each PDF after the first heading and date in the document," or "Name photos by location and time of day." These prompts can be saved as reusable presets and combine the flexibility of AI with your own instructions. Since NameQuick uses BYOK for AI, you control which service processes your data and can even run locally via Ollama.
Watch Folders and batch processing
One of NameQuick's standout features is Watch Folders. You can point the app at a folder (with optional subfolders) and have it continuously scan for new files. When new items appear, NameQuick indexes them and can automatically apply Smart Rename or a preset. This is invaluable for photographers importing images from an iPhone or DSLR: drop your photos into the watch folder and watch them immediately renamed and organised. Watch Folders support bulk batch rename operations, and because the app runs in the menu bar, you can process downloads, screenshots or incoming scanned documents without leaving your workflow.
Batch processing can also be triggered manually: you can drag and drop a batch of files or use the menu-bar icon to run a preset. The system is robust enough to handle different file types -- JPG, PNG, PDF, DOCX, CSV -- while preserving file extensions and preventing collisions. For safety, NameQuick will block renames if the output is invalid, provide a Clean Filenames option to strip forbidden characters, and always allow you to undo changes.
Rules automation
Beyond basic renaming, NameQuick includes a powerful Rules engine. Rules let you define conditions to decide when and how files are renamed or moved. There are more than seventeen condition types, including filename regex matches, file size thresholds, creation or modification dates, and EXIF metadata such as camera make/model, GPS coordinates, dimensions, date taken and orientation. You can also use video attributes (duration, codec) and combine conditions with AND/OR logic. Rules run in both pre-AI and post-rename phases, allowing you to validate names before processing and automate follow-up actions afterwards.
A rule can, for instance, look for photos taken with a Nikon camera, then move them into a path template like {year}/{month}/{camera_make}/, assign a blue Finder color label, add a descriptive comment and adjust file dates. Another rule might detect PDFs larger than 10 MB and move them into an Archive folder. Because rules support placeholders, you can create smart path templates that mirror how you'd manually organise files. NameQuick's safety features ensure no collisions occur -- files aren't overwritten, and if a name already exists, the app safely increments a digit or prompts for resolution.
Finder integration and Library
NameQuick integrates seamlessly with the Finder. A menu-bar icon, context-menu action and shortcut (set via System Settings) let you rename selected files without switching apps. It also provides a Library view where you can search by original names, paths, AI-generated descriptions or Finder tags. Filters allow you to narrow results by watch folder, state (new, processed, skipped) or tags. Multiple views (list, grid, timeline) help you visualise your assets, and you can remove items from the library or move them to the trash directly from NameQuick.
Automation and workflows: transforming real-world use cases
NameQuick isn't just a rename tool -- it's an organiser designed for busy professionals. Consider a wedding photographer juggling thousands of RAW and JPG files. Using Watch Folders, every imported image is scanned; a template extracts the date taken, camera model, and key descriptors from the AI (e.g., "ceremony," "garden," "sunset"), then applies a sequential counter. A rule moves each file into a 2025/03/15/Canon/ directory and assigns a purple tag for easy sorting. The result: logically organised, searchable images without manual typing.
Another scenario involves researchers who download academic papers and meeting minutes. A Custom Prompt can rename each PDF by its first heading and the date within the document. The rule engine then moves the renamed PDFs into a folder structure like {year}/{month}/{topic}, adds Finder comments summarising the content and marks them with a green label for "Reviewed." Because NameQuick can extract text from Office OpenXML documents and perform OCR on scans, it works equally well on scanned transcripts and Word files.
Even everyday tasks benefit. Imagine your Downloads folder: invoices, receipts, exported CSV files and zipped projects all accumulate. By assigning a Watch Folder, NameQuick automatically cleans file names with the Clean Filenames option, adds a prefix indicating the source (e.g., "Invoice_" or "Report_") and increments a counter when duplicates occur. The suffix can include the download date (with the {date:yyyy-MM-dd} placeholder), making it trivial to spot the latest version. Combined with a rule that archives files older than 30 days, your downloads remain tidy.
