Why trust us
Your files stay yours
All 249 published tools process your input in your browser — nothing is uploaded, so there is no server-side copy to keep. Read the privacy page.
No account, ever
There is no sign-in, no profile and no password to reset. Open a tool, use it, close the tab.
Free, with nothing sold
No advertising and no paid tier: the reserved ad slots render nothing and no payment code exists in the project.
Claims you can check
Limits and formats on a page are read from the code that enforces them, and the methodology page describes how each page is written and reviewed before it goes live.

Frequently asked questions about Tools Hub
What is Tools Hub?
Tools Hub is a free collection of single-purpose utilities for text, images, PDFs, data files and everyday sums. Every published tool runs inside your browser, so the words you paste and the files you open stay on your own device, and no account is needed to use any of them.
Do I need an account or a subscription?
No account, subscription or trial is involved. Tools Hub has no sign-in system at all, so you open a tool, use it, and close the tab. Because nothing is stored on a server, there is no profile to manage and no password to reset.
Is my data uploaded when I use a tool?
No. Every published tool processes its input locally with code that runs in your browser, so pasted text, images and documents are never sent to a server. The site has no endpoint that accepts a file. Assistants shown in review are not published.
Are the tools free, and what are the catches?
Each tool is free, with no account and no paid tier that unlocks extra features. The real limits are stated on each tool page, such as a file-size or page-count cap, so you can see what a tool will accept before you start work with it.
