Why this site
Built the way tools should be built
Three decisions shape everything here — and none of them are negotiable.
Fast
Every tool runs on your own device, so there is no upload, no queue and no round trip to a server. Results appear as you type.
Privacy first
The text, files and figures you paste in never leave your browser. Nothing is transmitted, stored or logged — there is nothing to leak.
Free forever
No account, no email wall, no trial that expires. Open the tool you need, use it as often as you like, and close the tab.

FAQ
Questions, answered plainly
If something is still unclear, the repository has the rest of the detail.
Ask on GitHubAre the tools really free?
Yes. Every tool on Inertia Pixel Tools is free to use with no usage caps, no trial period and no paid tier hidden behind the useful features. There is nothing to unlock.
Do I need an account?
No. There is no sign-up, no email wall and no login. Open a tool and start working — the site never asks who you are.
Is my data uploaded to a server?
No. The tools run entirely in your browser using client-side JavaScript, so the text, files and numbers you paste in never leave your device. Nothing is transmitted, stored or logged.
Do the tools work offline?
Once a tool has loaded, it keeps working without a connection because all of the processing happens locally. You only need the network to load the page itself.
Can I use the tools for commercial work?
Yes. Output from the tools is yours to use in client work, commercial products and internal systems. No attribution is required.
How often are new tools added?
Every tool that ships is dated and listed under Recently Added, so you can see exactly what has changed and when.
Can I request a tool?
Yes. Requests and bug reports go through the GitHub repository.
