The small tools you reach for every day, in one place
Netaru Tools collects the little utilities you need in the middle of a task. Everything runs inside your browser, so the text you paste never reaches a server — and there is nothing to sign up for.

About Netaru Tools
Checking whether a config file parses, reading through an API response, converting a color a designer handed you into another notation — these interruptions happen many times a day. Searching for a site to do each one, then pasting work data into whatever comes up first, costs both time and peace of mind.
Netaru Tools exists to absorb those interruptions. Every tool does its work entirely in the browser, so the text you paste never travels over the network. That makes it safe to use with internal config files, API responses and anything else you would rather not upload.
Your input is kept in your browser's local storage, so closing the tab does not lose your work. That storage lives on your device only — it is not something this site can read.
Why this site
Everything stays local
Parsing and conversion happen in JavaScript in your browser. No input is ever uploaded.
No accounts, no installs
Open the page and start typing. There is nothing to register for and nothing to download.
Your work is remembered
Input and pane widths are saved locally, so you can pick up exactly where you left off.
Works offline
Once a page has loaded it keeps working without a connection — handy on a train or a flaky network.
Frequently asked questions
Is anything I paste sent to a server?
No. Every tool runs entirely in your browser. Disconnect from the network and the pages keep working — the easiest way to confirm it for yourself.
Do the tools cost anything?
All of them are free. Running costs are covered by advertising.
How do I clear what I have typed?
Use the clear button in each tool, or delete this site's data from your browser settings. Everything is stored in local storage on your device.
Do the tools work on a phone?
Yes. The layout adapts to the screen: on narrow screens the side-by-side panes stack vertically instead.
