A growing set of tools in 1 place.
Batch-process videos, images, audio, documents and game assets on your own computer.
No account. No cloud. No credits.
⬇ Download for Windows · See all tools · Run from source
- Everything in one place. Compress video, resize and clean up images, remove backgrounds, convert files, build Unity packages and more, without hunting for a separate program for each job.
- Safe by default. Every tool shows a preview of what it will do before it writes anything, and your original files are never overwritten unless you turn that on and confirm.
- Private and offline. Your files never leave your computer. The only time it goes online is if you choose to download the optional AI models.
- Portable. On Windows there is nothing to install: unzip the folder and double-click
KS ToolBox.exe. - Built for big batches. Drop in hundreds of files, watch progress in the Queue, and get a report at the end. A broken file doesn't stop the rest.
- Open a work area or press Ctrl/Cmd+K to search for a tool.
- Add files or a folder, set the output location, and inspect the preview.
- Turn off Preview only only when the planned outputs look right.
- Watch progress in the tool or Queue; each real run leaves a manifest and completion report beside its output where applicable.
The source files are never overwritten by default. A destructive option is always explicit and confirmed.
| Tool | What it does |
|---|---|
| Video Compressor | Shrink videos without visible quality loss — decides if a file is even worth re-encoding, then proves the result with a VMAF quality gate before touching the original. |
| Video Chopper | Split a video into clips at black-frame gaps (scene/take boundaries). Lossless stream-copy or frame-accurate re-encode. |
| Audio Tool | Batch convert / trim / fade / loudness-normalize audio via the bundled FFmpeg. |
| Format Converter | Convert images, audio/video, and documents through verified local adapters. |
| Tool | What it does |
|---|---|
| Image Enhancer | Local batch restoration, CLAHE, Wavelet de-gloss, skin-tone QA, creative grades, and optional micro-model rack (SPAN, SAFMN, RAMiT, SCUNet, NAFNet, DehazeFormer, CodeFormer, AnimeGANv2) — no ComfyUI or cloud. |
| Image Rescale | Batch-resize four ways (longest-side, megapixels, scale factor, fit-inside), with snap-to-grid, safe upscale gating, and optional local Real-ESRGAN AI upscale. |
| Metadata Scrubber | Batch remove EXIF, GPS coordinates, camera serials, and AI generation parameters/prompts from PNG, JPEG, and WebP. |
| Pixel Art Converter | Turn images into clean pixel art — chunky pixels, reduced palette, sharp alpha. |
| To SVG | Vectorize raster images to SVG (vtracer). |
| Font Builder | Turn a folder of letter images or SVGs into a real TrueType (.ttf) font, with automatic glyph naming and spacing. |
| Icon Normalizer | Trim, square-pad, and resize icons/sprites to a uniform canvas. |
| Showcase | Present your work: contact sheets, framed hero renders, and before/after comparisons. |
| Tool | What it does |
|---|---|
| Alpha Doctor | Remove backgrounds & repair alpha — deterministic chroma / auto-solid / edge-flood keying + despill/defringe/premultiply, with an optional U2Net method for hard photos. |
| Material Converter | Pack/convert/rename PBR texture-map sets — ORM/MOS packing, DirectX↔OpenGL normals, gloss↔roughness, Unity/Unreal/Godot/Blender/glTF presets. |
| Sprite Viewer | View & play sprite sheets and animations — grid/cell/auto-detect slicing, playback, slice-grid overlay. |
| Seamless Checker | Interactive 3×3 wrap inspector and redo triage — dual-pass PBR and standalone detection, mouse zoom/pan, all-or-nothing Redo transfer. |
| Tileset Checker | Score & preview how seamlessly a texture tiles — seam score, offset preview, N×N tile montage. |
| Texture Renderer | Batch-export textures from Substance Designer (.sbsar) and Material Maker (.ptex) projects. (requires those external tools) |
| Package Extractor | Extract Unity .unitypackage + zip/tar archives and rebuild the original folders — with zip-slip / symlink / decompression-bomb guards. |
| Unity Packager | Build a .unitypackage from a project folder without opening Unity — preview, safe paths, duplicate-GUID check, deterministic output. |
| Tool | What it does |
|---|---|
| Asset Auditor | Find duplicates (exact + perceptual), corrupt/empty/oversized files, unsafe names, and resolution issues → HTML/JSON/CSV report. |
| Dataset Manager | Pair images with captions, split train/val/test, bucket by resolution, batch-edit captions — copy-only, never destroys originals. |
Every batch tool previews before it writes, never touches originals unless you explicitly opt in (with a confirmation), and writes a manifest plus machine-readable completion report.
Windows (no Python needed). Download the zip from the Releases page, unzip it anywhere, and double-click KS ToolBox.exe. Python and everything else is already inside the folder.
From source (Windows, Linux or macOS). You need Python 3.12.
python -m venv .venv
.venv/Scripts/python -m pip install -r requirements.txt # Windows; on Linux/macOS use .venv/bin/python
.venv/Scripts/python -m pip install -r requirements-optional.txt # optional: extra features for some tools
.venv/Scripts/python main.pyThe video and audio tools need FFmpeg. The Windows download already includes it; from source, put ffmpeg and ffprobe on your PATH or in a bin/ folder.
While all tools run 100% deterministically without neural models, KS ToolBox supports optional micro-models for AI super-resolution, background segmentation, and face detection.
1-Click In-App Download: You can download the recommended micro-models (~4.8 MB total: YuNet Face Detector + U2NetP Subject Mask) directly inside the app with a single click using the Download AI Models button in the sidebar (located directly above the Free AI Models (RAM) button).
See MODELS.md for the complete list of supported models, direct download links, and manual setup instructions.
powershell -File build.ps1Produces dist/KS ToolBox/ — a portable folder with a bundled Python. See
THIRD_PARTY_NOTICES.md for the bundled-runtime inventory when redistributing.
The build fails on unknown bundled package licences and generates
SBOM.spdx.json, DEPENDENCY_MANIFEST.json, RELEASE_COMPONENTS.md, exact
licence texts, binary hashes, and FFmpeg build/source evidence.
- Engine ≠ UI. Each tool is pure headless logic (
engine.py) + a thin UI (panel.py). Errors are values (a standard envelope), never crashes. - Deterministic-first. Most tools use no model at all. Alpha Doctor and Image Enhancer expose optional compact local utility models only when requested; no cloud account or always-on service is required.
- Lazy & portable. A tool's heavy dependency loads only when you open it; a missing one is announced in-panel, never a startup failure.
See each tool's guide in Tools above for specific options, supported formats, and settings.
