Tips, tutorials, and updates from the team behind Sakarto — the free browser-based duplicate file finder. Learn how to clean up duplicate images, videos, and audio files without installing anything.
Upload a reference image or video and Sakarto finds all similar copies using pHash (Perceptual Hash) — the DCT‑based algorithm that detects re‑compressed, resized, watermarked, and lightly edited copies. Free, browser‑based, and 100% private.
Upload a reference image or video and Sakarto finds all similar copies using wHash (Wavelet Hash) — a multi-level Haar wavelet transform that balances speed and accuracy. Perfect for finding re-compressed, resized, and lightly edited copies of a specific file. Free, browser-based, and 100% private.
Upload a reference image or video and Sakarto finds all similar copies using ORB feature matching—the only algorithm that handles rotation, cropping, and perspective distortion. Perfect for finding geometrically transformed copies of a specific file. Free, browser-based, and 100% private.
Sakarto's Chromaprint-inspired algorithm finds duplicate and similar audio files using spectral fingerprinting—perfect for re-encoded tracks, different bitrates, and near-identical audio. Free, browser‑based, and 100% private.
Sakarto's Essentia HPCP algorithm finds duplicate and similar audio files by harmonic content—catching cover versions, live recordings, and alternate arrangements that spectral methods miss. Free, browser‑based, and 100% private.
Sakarto's Meyda MFCC algorithm finds duplicate and similar audio files by timbral texture—perfect for speech, podcasts, voice memos, and sound effects where pitch-based methods fail. Free, browser‑based, and 100% private.
Upload a reference audio file and Sakarto finds every similar copy in a folder using Chromaprint-inspired spectral fingerprinting. Pure browser JS, no uploads, reference pinned and protected.
Upload a reference audio file and Sakarto finds every harmonically similar copy in a folder using Essentia.js HPCP—perfect for covers, live recordings, and alternate arrangements. Free, browser‑based, and 100% private.
Upload a reference audio file and Sakarto finds every timbrally similar copy in a folder using Meyda.js MFCC fingerprinting—perfect for speech, podcasts, voice memos, and sound effects. Free, browser‑based, and 100% private.
Sakarto's Media Viewer lets you browse images and videos in any folder with masonry layouts, auto-scroll, play-all, and custom queues. Read-only, 100% local, and zero installation.
