Phosor — Product Documentation

Version 0.9.21 (Internal Beta) Internal documentation and feature overview for beta testers.

Beta Status

Phosor is currently in an Internal Beta stage. Features may change before the public release. Performance may occasionally be inconsistent depending on hardware, image formats, and library size. Unexpected bugs may still occur. Feedback from beta testers is highly appreciated.


What is Phosor?

Phosor is a desktop application designed to help photographers quickly browse, evaluate, and organize large collections of photos. It provides a fast, keyboard-driven culling experience in a lightweight, single-file application for Windows, macOS, and Linux.

Phosor solves the slowness often found in heavy photo management software by pairing fast file-system handling with a clean, responsive interface. The application focuses purely on culling — the process of selecting the best shots from a shoot — and avoids complex database management or editing features.

Non-destructive by design

Phosor moves original files to organized folders without modifying their contents. Your photos are never altered.

Photographers can sort hundreds of photos in minutes using only the keyboard, then execute a batch move to distribute files into category-specific destination folders.


Key Highlights

  • Keyboard-driven culling — Sort photos at speed using custom keybindings.
  • Non-destructive workflow — Original files are moved, never modified.
  • Cross-platform — Runs on Windows, macOS, and Linux as a single-file application.
  • RAW support — Displays RAW files from major camera manufacturers.
  • Batch move — Distribute sorted photos to category-specific folders in one operation.
  • Undo/redo — Up to 100 levels of history for all sorting actions.
