PBRenamer

A cross-platform graphical batch file renaming utility built with Qt 6 (PySide6).

PBRenamer lets you rename hundreds of files at once using patterns, substitutions, counters, date stamps, and metadata — all previewed live before any change is applied.

Features

• Live preview with conflict detection — renamed entries that collide with existing files or with each other are highlighted in red; the Rename button is disabled until all conflicts are resolved
• Multi-selection — apply transformations to selected files only
• Flexible renaming rules
  • Pattern-based search / replace ({#}, {L}, {X}, {@}, capture groups…)
  • Text substitution (find & replace, spaces ↔ underscores / dots / dashes, case)
  • Counter ({num}, {num:03} zero-padded, {num::10} start offset), conflict-free auto-number ({newnum})
  • Dates ({date}, {datetime}, {mdatetime} file-modification time), parent-folder name ({dir})
  • Image metadata ({im:Make}, {im:Model}, {im:DateTimeOriginal}… — EXIF/IPTC via Pillow)
  • Audio metadata ({au:Title}, {au:Artist}, {au:Album}, {au:Year}… — via mutagen)
  • Video metadata ({vi:Title}, {vi:Duration}, {vi:Width}, {vi:Height}, {vi:VideoCodec}… — via pymediainfo)
  • Mixed-type templates: combining {im:…}, {vi:…} and {au:…} in the same replacement field works across file types — the non-matching tokens silently produce nothing (e.g. {im:DateTimeOriginal:%Y-%m-%d:}{vi:encodeddate:%Y-%m-%d:} uses the EXIF date for images and the encoded date for videos)
• Directory colouring — directories are shown in a distinct colour in the file list
• Keep extension option — transformations apply to the stem only
• Recursive directory traversal
• Undo — revert the last rename batch in one click; the button shows the number of batches available for undo
• Pattern presets — save and reuse search/replace pairs
• Pattern history — LRU drop-down lists for search and replacement fields; full history browsable and editable via the History dialog
• Directory shortcuts — Shortcuts menu combines system bookmarks (GTK / macOS / Windows) with user-defined favourite directories for fast navigation; last-used directory is restored on startup
• File info — dedicated window showing filesystem metadata and embedded EXIF/ID3/media tags for any selected file
• Window state persistence — window size, position, and splitter ratios are saved and restored between sessions
• Case-aware conflict detection — honours the case sensitivity of the underlying filesystem (case-insensitive on Windows/macOS by default)
• Internationalised — English and French included; additional languages can be added via gettext .po files
• Cross-platform — Linux, macOS, Windows

Download

Pre-built standalone executables are attached to every GitHub release:

Platform	File
Linux x86-64	pbrenamer-<ver>-linux-x86_64
Windows x86-64	pbrenamer-<ver>-windows-x86_64.exe
macOS (Apple Silicon)	pbrenamer-<ver>-macos-arm64.zip

No installation required — just download and run.

Installation from source

Requirements

• Python 3.12 or later
• PySide6 6.6 or later (Qt 6)

From PyPI

pip install pbrenamer

On Linux, pip install cannot register an application menu entry by itself (pip has no post-install hook). Run this once after installing to add a menu entry and icon for the current user:

pbrenamer --install-desktop-entry

Remove it again with pbrenamer --uninstall-desktop-entry.

From source

git clone https://github.com/ppoilbarbe/PBRenamer.git
cd PBRenamer
pip install .

Usage

GUI mode

pbrenamer            # launch the GUI (last-used directory)
pbrenamer /path/dir  # launch the GUI starting in a given directory (use '.' for current)
python -m pbrenamer  # launch from source

pbrenamer --help     # show command-line help and exit
pbrenamer --version  # print version and exit

Qt platform options (--style, --platform, --display, …) are forwarded to Qt and can be combined with the above flags.

Headless (command-line) mode

Providing --search disables the GUI and renames files directly from the terminal. All options that exist in the main window are available:

pbrenamer [DIR] --search TEXT [--replace TEXT] [OPTIONS]

Option	Default	Description
-s, --search TEXT	(required¹)	Search pattern — activates headless mode
--saved NAME	(required¹)	Load a named preset — activates headless mode; CLI options override preset values
-r, --replace TEXT	""	Replacement string
--mode {pattern,regex,plain}	pattern	Search mode
--list {files,dirs,all}	files	Entry types to process
--recurse / --no-recurse	--no-recurse	Recurse into sub-directories
--keep-ext / --no-keep-ext	--keep-ext	Preserve the file extension
--filter GLOB	(none)	Restrict listing to matching entries
--accent / --no-accent	--no-accent	Strip diacritics from result names
--dup / --no-dup	--no-dup	Collapse consecutive duplicate separators
--sep {none,space-underscore,…}	none	Separator conversion applied after rename
--case {none,upper,lower,capitalize,title}	none	Apply capitalisation after rename
--confirm / --no-confirm	--no-confirm	Preview and confirm before renaming
--debug / --verbose / --quiet	(saved pref)	Override the saved log-level preference
--config-dir DIR	(platform default)	Override the configuration directory (intended for testing)

¹ Exactly one of --search or --saved is required.

Examples

# Replace underscores with hyphens, preview first
pbrenamer ~/Photos --search "_" --replace "-" --mode plain --confirm

# Number all JPEG files: photo_001.jpg, photo_002.jpg, …
pbrenamer ~/Photos --search "{L}" --replace "photo_{num:03}" --filter "*.jpg"

# Strip diacritics and upper-case everything, recursively
pbrenamer ~/docs --search "{X}" --replace "{1}" --recurse --accent --case upper

# Rename using a regex capture group
pbrenamer . --search "img(\d+)" --replace "photo_{1}" --mode regex

Conflicting renames (two files mapping to the same target, or target already exists) are detected and skipped automatically; --confirm shows them flagged as [CONFLICT] before you confirm.

The development environment is managed with pixi, but all make targets can run against a plain Python environment by setting NOCONDA=1 (see CODING.md).

PBMou is a cross-language pun: "PB" stands for "Poilbarbe", and "Mou" is the French translation of "Soft" — so PBMou reads like "PBSoft" half-translated into French.
