Major speedups for large-folder thumbnail generation: - JPEGs decode through mozjpeg at the smallest DCT scale covering 320px instead of full resolution, with catch_unwind and a fallback to the image crate for anything mozjpeg rejects. EXIF orientation preserved in both paths. - RGB8 pipeline end to end (no RGBA round-trip) and CatmullRom resize in place of Lanczos3. - Video posters grab the seeked frame directly instead of running the ffmpeg thumbnail filter (which decoded ~100 frames), with decode threads capped at 2 per process. - Workers only sleep when the queue is empty rather than 250ms after every batch. Image batches commit before videos start, and videos run sequentially off the rayon pool (blocking ffmpeg waits were starving image decode) with per-item commits so progress keeps moving through slow stretches.
Phokus
A local-first desktop media library for browsing, filtering, and curating image and video folders.
Features
- Add and remove media folders; background indexing with live progress
- Browse all media or filter by folder, type (image/video), favorites, or star rating
- Filename search, semantic search (
/s query), and tag search (/t tag) - Similar image search — find visually similar media by image or selected region
- AI tagging via WD tagger (ONNX, CPU/DirectML) with confidence threshold control
- Explore view — visual cluster map and tag cloud for browsing by theme
- Duplicate finder — scan for exact duplicates by file hash with bulk delete
- Lightbox preview with keyboard navigation, inline tag editing, and rating controls
- Sort by date, name, size, rating, or duration
- Grid density controls (compact / comfortable / detail)
Supported formats
| Images | Videos |
|---|---|
| jpg, jpeg, png, gif, bmp | mp4, mov, m4v |
| tiff, tif, webp, avif, heic, heif | webm |
Stack
- Tauri 2 + Rust backend
- React 19 + TypeScript + Zustand
- SQLite +
sqlite-vec(vector search) - ONNX Runtime (
ort) for AI tagging - Candle (Rust ML) for visual embeddings
- FFmpeg sidecar for video thumbnails and metadata
- Vite + Tailwind CSS v4
Development
Prerequisites: Node.js 20+, pnpm, Rust toolchain, Tauri system prerequisites for Windows.

How it works
- Add a folder from the sidebar — the Rust indexer walks it recursively.
- Supported files are written to SQLite with metadata (path, dimensions, media type, etc.).
- Background workers generate thumbnails, compute visual embeddings, and run AI tagging.
- Progress events stream back to the UI while the gallery updates incrementally.
- Embeddings power semantic search and the similar images feature via an HNSW index.
