What PicSift Does

Multi-Tier Duplicate Detection

Finds exact byte-identical copies, pixel-identical re-encodes, and near-duplicates using three perceptual hash algorithms with vectorized NumPy comparison.

Quality-Based Keeper Selection

Scores every file on resolution, sharpness, compression, metadata richness, and screenshot likelihood — keeps the best, quarantines the rest.

Shoot Grouping

Clusters photos from the same session using perceptual similarity and timestamps, so sequential renames keep shoots together.

Video Support

Extracts keyframes from videos and compares them alongside images. Supports MP4, MOV, AVI, MKV, and more.

Full Safety Net

Preview before executing. Duplicates move to quarantine — never deleted. PowerShell rollback script generated for every operation.

Audit Trail

CSV reports, JSON logs, and an optional HTML review gallery so you can verify every decision PicSift made.

How It Works

  1. Point PicSift at a folder — images, videos, or both, with optional recursive scanning.
  2. Preview the plan — PicSift analyzes every file, groups duplicates, picks keepers, and shows you the results before anything moves.
  3. Execute with one click — duplicates go to quarantine, keepers stay put, and a rollback script is saved just in case.
  4. Sequential rename (optional) — groups similar shots together and renames them in order: Photo (1).jpg, Photo (2).jpg, etc.

FAQ

Does PicSift delete my files?

No. Duplicates are moved to a quarantine folder — your originals are never deleted. A PowerShell rollback script is generated with every operation so you can undo everything instantly.

What image and video formats are supported?

Images: JPG, PNG, GIF, BMP, TIFF, WebP, HEIC. Videos: MP4, MOV, AVI, MKV, WMV, FLV, WebM. Video analysis requires ffmpeg on your PATH.

How does duplicate detection work?

PicSift uses three tiers: Tier 1 (exact) compares SHA-256 and pixel hashes, Tier 2 (near-duplicate) uses three perceptual hash algorithms (pHash, dHash, aHash) with vectorized comparison, and Tier 3 detects screenshot variants. You control the sensitivity threshold.

What's the difference between Starter and Unlimited?

Both include all features. Starter activates on 1 PC with 1 year of updates. Unlimited activates on as many PCs as you need with lifetime updates.

Is there a trial or refund policy?

We offer a 14-day refund if the license hasn't been activated. Reach out to support@wigleystudios.com within 14 days of purchase.

Does it require an internet connection?

Only for initial activation and periodic validation (once per week). PicSift works fully offline between validations, with a 30-day grace period if you're disconnected.
