Sakarto brings 7 visual and 3 audio algorithms straight to your browser with zero uploads. We dive into the tech, the algorithms, and why it beats installing native tools for daily cleanup.
Sakarto's file organizer lets you browse, delete, move, and rename files directly in your browser—no installation, no scanning, no fuss. We break down Media Viewer, Bulk Delete, Bulk Move, and Bulk Rename.
Sakarto's Color Signature algorithm finds duplicate photos and videos by comparing actual colour content across a 24×24 YUV grid. Free, browser-based, and 100% private. Learn how it works and when to use it.
Sakarto's aHash (Average Hash) algorithm finds duplicate photos and videos in milliseconds by comparing brightness structure. Free, browser-based, and 100% private. Learn how to use it effectively.
Sakarto's BlockHash algorithm finds duplicate photos and videos by comparing block‑averaged brightness. Perfect for heavily compressed JPEGs, scanned documents, and noisy image collections. Free, browser‑based, and 100% private.
Sakarto's dHash (Difference Hash) algorithm finds duplicate photos and videos by comparing edge and gradient structure—not absolute brightness. Perfect for exposure‑adjusted, HDR, and color‑graded copies. Free, browser‑based, and 100% private.
Sakarto's pHash (Perceptual Hash) algorithm finds duplicate photos and videos using the same Discrete Cosine Transform as JPEG compression. Perfect for re‑compressed, watermarked, and lightly edited copies. Free, browser‑based, and 100% private.
Sakarto's wHash (Wavelet Hash) algorithm finds duplicate photos and videos using a Haar Wavelet Transform—faster than pHash with near-identical accuracy. Perfect for large collections where speed matters. Free, browser-based, and 100% private.
Sakarto's ORB feature matching algorithm finds duplicate images and videos using OpenCV.js keypoint detection—the only algorithm that handles rotation, cropping, and perspective distortion. Free, browser‑based, and 100% private.
Upload a reference image or video and Sakarto finds all similar copies using Color Signature matching — the only colour-aware algorithm. Perfect for tracking down copies of a specific photo across your archives. Free, browser-based, and 100% private.
Upload a reference image or video and Sakarto finds all similar copies using aHash (Average Hash) — the fastest algorithm for large folders. Perfect for finding resized, re-compressed, and format-converted copies of a specific file. Free, browser-based, and 100% private.
Upload a reference image or video and Sakarto finds all similar copies using BlockHash — the noise-tolerant block-averaging algorithm. Perfect for finding heavily compressed, re-encoded, or noisy copies of a specific file. Free, browser-based, and 100% private.
Upload a reference image or video and Sakarto finds all similar copies using dHash (Difference Hash) — the gradient‑based algorithm that ignores brightness and exposure changes. Perfect for finding colour‑graded, brightness‑corrected, and exposure‑adjusted versions of a specific file. Free, browser‑based, and 100% private.
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.
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.
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.
Sakarto's Bulk Delete tool lets you select and permanently delete multiple files at once—images, videos, audio, documents, and archives. Queue Mode adds a safety net. Free, browser‑based, and 100% private.
Sakarto's Bulk Move tool lets you select and move multiple files at once to a new subfolder—images, videos, audio, documents, and archives. Queue Mode adds a safety net. Free, browser‑based, and 100% private.
Sakarto's Bulk Rename tool lets you rename multiple files at once with 14 powerful patterns—dates, timestamps, sequential numbering, custom names, and more. Preview before executing, with conflict detection. Free, browser‑based, and 100% private.
