Mass Rename: File Batch Rename

Description

Mass Rename — rename, number, and organize thousands of files in seconds. Stop renaming files one by one. Mass Rename lets you build a renaming rule once, preview every change live, and apply it to your whole folder in a single click — from a handful of photos to tens of thousands of files. NEW IN 2.0 Completely rebuilt, with on-device AI Smart Rename, reusable renamer workflows, folders to keep them organized, and a live preview that stays fast at massive scale. AI SMART RENAME — ON-DEVICE & PRIVATE Let your Mac read what's actually inside a file and give it a clear, descriptive name. "Untitled.pdf" becomes "Acme Corporation Invoice." "scan_0042.pdf" becomes "Residential Lease Agreement." It all runs on-device — nothing is ever uploaded. (Requires macOS 26 with Apple Intelligence.) BUILD REUSABLE WORKFLOWS Chain simple steps into powerful renamers you can save, organize into folders, and reuse anytime: • Custom Format — mix your own text with tokens: file name, parent folder, sequence numbers, dates, and metadata • Find & Replace — plain text or full regular expressions • Add a prefix or suffix, set or change the extension • Change case — UPPERCASE, lowercase, Title Case, Sentence case • Insert or remove characters at any position • Sequential numbering with custom start, step, and digits RENAME BY REAL FILE INFO • Photos — by dimensions, camera model, or date taken • Music — by title, artist, album, track number, and year • Dates — created, modified, or added, in the format you choose PREVIEW EVERYTHING. UNDO ANYTHING. See the old name and new name side by side for every file before you commit, with automatic conflict handling so nothing gets overwritten. Changed your mind? Undo the entire batch in one click. RENAME FILES AND FOLDERS Rename folders too — not just the files inside them. When you add items, choose to include files, folders, or both. BUILT FOR BIG JOBS Drop in an entire folder — even tens of thousands of files — and Mass Rename stays smooth and responsive, filling in the preview as you go. Perfect for photographers, designers, developers, music libraries, cluttered Downloads folders, scanned documents, and anyone tired of messy filenames. Rename smarter — with Mass Rename.

SEND FILES STRAIGHT FROM FINDER Control-click files and choose Services → Rename with Mass Rename, use Open With, or drop them onto the Dock icon. Don't see the Services entry? Turn it on in System Settings → Keyboard → Keyboard Shortcuts → Services. NUMBER RAW + JPEG PAIRS TOGETHER Turn on "Same number for files with the same name" in a Sequence action, and IMG_0001.jpg and IMG_0001.dng get the same number. RENAME IN SEVERAL ROUNDS Keep Files in List runs another renamer on the same files, just like the original Mass Rename. Undo Rename steps back one round at a time. TYPE A NAME YOURSELF Double-click a new name, or right-click and choose Edit New Name…, to set one file's name exactly. SORT BY DATE TAKEN Put photos in shooting order. "Photo taken" in the Date action now always reads the photo's own date. FILTER BY KIND AND EXTENSION Show only images, or just .jpg files. Rename applies to the files shown. FASTER AND MORE RELIABLE Fields in actions take typing on the first click, big folders load much faster, and dragging actions and sidebar items works every time. Thanks for using Mass Rename!
