ToolHub
About ToolHub
ToolHub is a free collection of 54 online tools across 7 categories, built so everyday jobs like compressing a photo, merging a PDF or generating a password do not require installing software, creating an account or handing your files to a stranger.
How the tools work
Most tools run entirely inside your browser tab. Files you open are read by your own device, processed with JavaScript, Web Workers and WebAssembly, and the result is saved straight back to your device. Nothing is uploaded, so the tools work just as well for private documents as for public ones.
Four image tools (the resizer, converter, compressor and favicon generator) use our server when your browser cannot do the job, for example a very large image or an output format such as TIFF that browsers cannot write. Those files are processed to produce your result and are not stored.
ToolHub is also a progressive web app. Install it from your browser and the tools you have opened keep working offline.
What we stand for
Your files stay yours
Processing happens on your device wherever possible, and we never sell or share data.
Free for everyone
No accounts, no trials and no watermarks. Every tool is free to use.
Clear about limits
Each tool explains what it supports, its limits and when a server is involved.
Always improving
New tools and improvements ship regularly, and every tool page shows when it was last updated.
