Filesmith puts the everyday file jobs behind one clean window. Pick what you want done - convert, compress, resize, and more - then drop files of any supported type: images, video, audio, PDFs, documents, and archives. Drop a pile of files, pick a tool, and it runs the batch with thumbnails, live per-file progress, rich previews, and collision-safe output that never overwrites your originals.
Everything runs locally on your machine, and your queue and produced files are remembered across restarts, so you can close the app mid-batch and pick up where you left off.
- Images — convert (PNG / WebP / AVIF / JPG / JXL / TIFF / BMP / GIF / ICO), compress, resize, remove background, upscale (2–4×), and generate from a text prompt.
- Video / Audio — convert (container / codec) and compress, with live
ffmpegprogress and a resolution preview. - PDF — extract text, PDF to images, merge, split, burst, extract images, compress, and pack pages into a comic archive.
- Documents — convert office documents to PDF.
- Archives — convert between ZIP / RAR / 7z / TAR and the comic formats CBZ / CBR / CB7 / CBT, extract to a folder, and turn a comic archive into a PDF. Writing CBR/RAR needs WinRAR installed (it cannot be bundled); everything else works offline.
Plus batch queues, thumbnails for every kind (images, video frames, audio cover art), a built-in viewer for images, video, and audio (with a live circular visualizer), per-file progress with ETA, and cancel.
The everyday tools (convert, compress, resize, and all PDF / video / audio / document operations) run fully offline from bundled binaries, with no AI and no downloads. The AI features are opt-in, and nothing AI runs unless you choose it:
| Feature | What it needs |
|---|---|
| Remove Background | The free uv tool; a small AI model is downloaded on first use (once, then offline). The panel tells you before you commit files. |
| Upscale | An upscaling model, downloaded on first use. NVIDIA (PiD) mode needs an NVIDIA GPU. |
| Generate | An existing ComfyUI install, which Filesmith drives headlessly. Supports SDXL, Flux 1, Flux 2 (klein), Z-Image, and Krea 2 models; missing text-encoders / VAEs can be downloaded from the panel. If something is missing, the panel says exactly what to do. |
Don't want AI? Just use the core tools, and the AI features stay out of your way.
Download Filesmith-Setup-x64-<version>.exe from the latest release and run it. It installs per-user, so no admin rights are required.
The installer is unsigned, so Windows SmartScreen may warn on first run ("Windows protected your PC"). Click More info → Run anyway to proceed. Updates are manual: download and run the newer installer when a new release is out.
- Open Filesmith from the Start menu.
- Pick what you want to do in the left rail (Convert, Compress, Resize, Upscale, Remove BG, Generate, Tools).
- Choose a tool from the top-right (Convert, Compress, Resize, …), set its options.
- Drop files onto the drop zone (or click browse), then run.
Produced files land next to your inputs with a safe name (photo (converted).webp), never overwriting anything. Right-click a result to preview, reveal, or delete it.
Requires Node.js 20+ and Windows.
npm install
npm run dev # launch with hot reload
npm run typecheck # tsc project checks
npm run lint # eslint
npm test # unit tests (vitest)
npm run binaries # populate resources/ with the bundled tools (once, before packaging)
npm run package # build the Windows installer into dist/Stack: Electron + TypeScript, with a React + Vite + Tailwind renderer. Operations are performed by external tools (ffmpeg, ImageMagick, mutool, Ghostscript, CaesiumCLT, 7-Zip, LibreOffice, Real-ESRGAN, rembg, ComfyUI) that the app orchestrates; the core tools are bundled and the AI tools are resolved from your machine or fetched on first use. See CLAUDE.md for architecture and scope.
