Bulk Rename Utility vs ExifRenamer

Bulk Rename Utility renames multiple files and entire folders in Windows using configurable rules. It can add, replace, or insert filename text, change case, alter extensions, and add dates or automatic numbers. A detailed preview shows proposed names before changes are applied. Rules can use photo EXIF data, MP3 ID3 tags, and Windows file properties. For more involved tasks, it supports regular expressions, JavaScript renaming, filters, subdirectory processing, and CSV input lists. The utility can create an undo batch file and save a log of renaming activity. Optional PDF and MediaInfo extensions expose document and audio/video metadata as tags, and require version 4.1.0.0 or newer. A portable version is available. The maker lists Windows 11, 10, 8, and 7, Windows on ARM, and specified Windows Server versions. Personal home use is free. Listed paid options include Home / Academic at $24.95 a month for one computer and a Commercial license at $92.95 as a one-time purchase per computer.

ExifRenamer is a free macOS app that renames photos, movie clips and audio clips from embedded date and time information. Its suggested YYYY-MM-DD_hh-mm-ss pattern gives filenames chronological order in Finder. Users can drag files onto the app icon or configure it as an automatic task in Apple Image Capture. A preview appears before renaming, with controls for naming styles, prefixes, suffixes, time-difference correction and sequence counters. The app can create a destination folder, move renamed files there and forward them to other applications. Listed formats include JPEG, TIFF, MOV, MP4, M4V, AVI, AIFF, AIF, WAV, MRW, NEF, CRW, CR2 and THM, with camera support including Casio, Olympus and Canon. ExifRenamer changes only filenames, not file contents. Some cameras may omit the required date and time metadata in supported formats, so extraction can fail. The page lists version 2.4.0 (15) and compatibility with macOS Sequoia. The plan is free, with optional donations.
