I Built ToolHub: Free Browser Based Tools That Keep Your Files Local

Hi DEV Community 👋

I'm building ToolHub, a collection of practical online tools for working with files, text, images, PDFs, code, audio, video, and more.

The idea is simple:

Useful tools without unnecessary complexity.

A big part of the project is privacy. Many tools process your files directly in your browser, so your files do not need to be uploaded to a server for processing.

What can you do with ToolHub?

ToolHub currently includes tools across multiple categories:

📄 PDF Tools

Merge, split, compress, convert, organize, sign, redact, OCR, and more.

🖼️ Image Tools

Compress, resize, crop, convert, edit, extract colors, OCR images, create collages, and more.

📝 Text Tools

Count words and characters, clean text, convert cases, compare text, find duplicates, format Markdown, and more.

💻 Developer Tools

Format and minify code, compare code, validate JSON, convert JSON, YAML and XML, encode Base64, decode JWTs, generate hashes and UUIDs, and more.

🎵 Audio and Video Tools

Convert, compress, trim, merge, record, and process media directly in your browser.

🧮 Math Tools

Calculators for scientific, graphing, matrix, programmer, and other mathematical tasks.

Why I built it

I often found myself searching for small online utilities for everyday tasks.

One site for merging PDFs.

Another for converting an image.

Another for formatting JSON.

Another for cleaning text.

So I started building ToolHub as one place where people can find useful tools without jumping between multiple websites.

Built with privacy in mind

Where possible, ToolHub processes files locally in the browser.

That means the goal is simple: your files stay on your device instead of being sent to a server for processing.

ToolHub is open source

I'm building ToolHub in public and would love feedback, suggestions, bug reports, and contributions from the community.
