What is Compareel?

Compareel is a free, open-source desktop application for Windows, macOS, and Linux that finds exact-copy and visually similar videos and images on local drives and displays matches side by side before anything is removed.

Instead of relying solely on similarity percentages, Compareel provides synchronized dual video playback with time offset adjustment, frame stepping, automatic partial-clip alignment, sampled audio comparison, and Wipe, Overlay, and Difference views with shared zoom and pan.

Key features:

  • Exact duplicate detection verified with full SHA-256 file hashes.
  • Perceptual similarity scanning for videos (with optional tolerance for black borders, mirroring, 90-degree rotations, and light cropping) and static, animated, multi-page, HDR, and camera RAW images.
  • Partial clip search across folders to locate trimmed video segments inside longer recordings.
  • Safe cleanup workflow that moves files only to the system Recycle Bin or Trash, enforces protected folders and per-file locks, ensures at least one copy per group is kept, and supports SHA-256 verified file transfers with persistent undo.
  • Completely local processing with no telemetry, cloud uploads, or network encoders, plus a built-in Privacy mode and 41 interface languages.
