Why Raykit
Mountains keep their secrets, tides keep their time — four promises behind every tool.
Fast by design
Results update as you type. No spinner waiting on a server, no queue — heavy work runs in Web Workers and WebAssembly, so the page stays smooth.
Private by default
Your JSON, tokens, images and PDFs are processed on your own machine. Nothing is sent, logged or stored on a server — there is no server-side processing at all.
Free, no account
No sign-up, no paywall, no ads between you and your work. Open a tool and use it.
Works your way
Any modern browser, light or dark, ten languages, and an interface you can tune — text size, density, font and colors.
How it works
Raykit is a static web app. Once a page has loaded, its tools need nothing but your browser.
You paste or drop
Text, files or images go into the tool — straight into the page's memory.
Your browser does the work
JavaScript, WebAssembly and Web Workers format, hash, compress or render it locally.
You get the result
Copy it or download it. Close the tab and it's gone — unless you chose to keep it.
No server in the loop
There is no API that receives your input, so it can't be read, logged or leaked on the way.
Tip: The first time a heavy tool runs — the AI background remover, for example — your browser downloads its engine once and caches it. Your files still stay on your device.

Working with a tool
Most tools follow the same simple flow.
Options
Choose how the result should look — style, indentation, dialect…
Input
Paste, type or drop a file. Load sample shows an example; Clear starts over.
Format

Tip: Inputs and options are remembered in this browser, so you can pick up right where you left off.

Light & dark
Follows your system, or pick one from the header.
10 languages

Your data, your device
What Raykit keeps, where it keeps it, and how to remove it.
What's remembered
Tool inputs and options, recent tools, shortcuts and UI preferences — saved only in this browser's local storage.
How to clear it
Use Clear inside a tool, or clear this site's data in your browser settings to wipe everything at once.
What never happens
No account, no tracking of what you type, no copy on any server. The only cookie remembers your language.
Questions & answers
Raykit never sends your input anywhere, so tokens, keys and data stay on your machine. As with any website, use a browser and device you trust.
Once a tool has loaded, the work happens locally — most tools keep working even if your connection drops.
Only your device's memory. Large files take longer on older hardware, but no server caps them.
Any recent Chrome, Edge, Firefox or Safari, on desktop or mobile. Some image tools run faster where WebGPU is available.
