Mac

Rename hundreds of files in seconds with live preview. 9 powerful rules, unlimited files, drag & drop. Automate your workflow with watched folders and Shortcuts. Batchio is the fastest way to batch rename files on your Mac. Drag in files or entire folders, set your rename rules, and see every change in real time before anything touches your disk. LIVE PREVIEW Every rename is shown side by side before you commit. Green checkmarks show changes, red warnings flag conflicts. Nothing happens until you click Rename. 9 POWERFUL RENAME RULES • Find & Replace with full regex and capture group support. Case sensitive toggle, match all or first only. • Add Text as prefix, suffix, or at any character position. • Sequential Numbering with custom start, step, padding, and format template like "Photo_###". • Change Case to UPPERCASE, lowercase, Title Case, or Sentence case. • Remove Characters: first N, last N, or a range. Strip spaces, special chars, diacritics, or emoji. Replace spaces with hyphens or underscores for clean filenames. • Date Insertion using file creation date, modification date, or current date in any custom format. • EXIF Metadata: rename photos by camera model, lens, ISO, aperture, shutter speed, focal length, or dimensions. Supports JPEG, HEIC, TIFF, and RAW. • Audio Metadata: rename music by title, artist, album, track number, genre, or year. Works with MP3, M4A, AAC, FLAC, WAV, and AIFF. • Change Extension: convert, remove, or normalize file extensions to lowercase or uppercase. CHAIN MULTIPLE RULES Stack as many rules as you need and apply them in sequence. Remove spaces, change case, and add a date prefix all in one operation. Reorder rules with drag and drop. Enable or disable individual rules without deleting them. PER-RULE FILE FILTERS Target each rule to specific files. Filter by extension, folder, or name pattern with optional regex. Apply EXIF rules only to photos while numbering everything else. SMART CONFLICT RESOLUTION Detects when files would end up with the same name. Block the rename, auto-number duplicates, or skip conflicting files. FULL UNDO & RENAME HISTORY Undo your last rename instantly with Cmd+Shift+Z. Browse your complete history with timestamps and file details. Keeps your last 100 operations. DRAG, DROP & ORGANIZE Drag files or folders directly into Batchio. Toggle subfolders with one click. Files group by source folder with collapsible headers. Sort by name, date modified, date created, size, or order added. Remove individual files or entire folders from the list. FOLDER AUTOMATION (Pro) Set up watched folders that rename new files automatically using your saved presets. Monitor Downloads, Camera Imports, or any folder that collects messy files. Run multiple automations simultaneously with activity logs. SHORTCUTS & SIRI (Pro) Use the "Rename Files with Preset" action in Apple Shortcuts. Specify folder, preset, and subfolder options. Works with Siri voice commands. FINDER QUICK ACTION (Pro) Right-click files in Finder and rename them with a saved preset without opening the app. SAVED PRESETS (Pro) Save your rule configurations for one-click reuse across the main app, Finder Quick Action, Shortcuts, and folder automation.
