ToolHub is a collection of 25-plus offline utilities, JSON formatter, image editor, PDF tools, audio player, and developer helpers, that run entirely in your browser or as a Windows desktop app with no data uploaded anywhere.
ToolHub is a collection of more than 25 practical utilities packaged as both a web app and a desktop application. The same codebase runs in a browser and as an installable desktop program on Windows, built using Electron. All tools process data locally: nothing is uploaded to any server. The interface uses a dark business theme and supports both Chinese and English.
The tools are organized into six categories. The JSON and data section includes a formatter, a tree viewer, converters between JSON and XML, YAML, and CSV formats, and a mock data generator for testing. The image tools cover cropping, editing with text and filters, format conversion between JPG, PNG, WebP, and SVG, batch compression, watermarking, and a color picker. Audio and video tools include a waveform audio player, an audio trimmer, and a local video player with screenshot support.
The document and office tools include a PDF merger and splitter, a PDF annotation tool, an Excel viewer, and a Markdown editor that previews output and can export to HTML or PDF. The encoding and encryption section covers Base64 conversion for text and images, hash calculation with MD5, SHA-1, and SHA-256, Unicode and URL encoding, and a regex tester. Developer utilities include a timestamp converter, color format converter between HEX, RGB, and HSL, a CSS unit calculator, and a text diff viewer.
The project is built with React 18, TypeScript, and Vite for the web layer, with Electron 28 for desktop packaging. It uses i18next for internationalization, pdf-lib and SheetJS for document handling, and wavesurfer.js for audio visualization. The source is organized by tool category under a single src/tools directory.
To use it locally, you clone the repository, run npm install, and start either the web development server or the Electron desktop mode. Building a packaged desktop app requires one additional command. The project is released under the MIT license.
Where it fits
- Convert between JSON, XML, YAML, and CSV without uploading sensitive data to an online converter.
- Edit, compress, or watermark images in bulk entirely on your own machine with no internet needed.
- Merge or split PDF files and annotate them locally without any cloud service or subscription.
- Use the regex tester, hash calculator, and text diff viewer as a private offline developer scratch pad.
