Why DupWiz?
A focused, reliable tool that does one job well.
Lightning Fast
Multi-threaded scanning with quick-hash pre-filter and SHA-256 verification. Handles millions of files without slowing down.
Safe by Default
Auto-backup before every deletion. Restore any removed file from the backup center. Your files are never lost.
Smart Matching
Beyond exact duplicates — find similar images, audio by acoustic fingerprint, and video by perceptual hash.
Four search modes, one workflow
Switch between specialized scanners for every file type.
Image
Perceptual hashing finds near-identical photos even when resized, compressed, or rotated. Match by dimensions, aspect ratio, EXIF date, and GPS.
Audio
Acoustic fingerprint comparison catches the same song across formats and bitrates. Group by ID3 tags — artist, title, album, track number.
Video
Thumbnail perceptual hashing identifies duplicate clips regardless of container. Match by duration and metadata tags.
Simple, honest pricing
Pay once. Use forever. No subscriptions, no hidden fees.
