About Everyday Kit
Free browser tools for everyday tasks—writing, encoding, security checks, developer helpers, and more. No account required.
Who runs Everyday Kit
Everyday Kit is independently run by Jeppe Johanson. It is a personal project, not a content mill: each tool is written and checked by hand, then shipped as a static page that you can use without an account.
The site exists to give people small, private utilities for writing, encoding, file conversion, and everyday calculations. If something is wrong or a tool would be more useful with a change, use the contact form.
How the tools are built
Tools run in your browser with client-side JavaScript. We do not scrape other sites for copy, auto-generate farms of near-duplicate pages, or send your pasted text to a server for processing. Conversion pages each have their own headings, examples, and FAQs for that unit pair.
What you see on a tool page is the working app plus a short guide: what the tool does, how to use it, and common questions. Longer explainers live in Guides. Limitations are listed on this page and on tools where the output is heuristic (password strength, JWT decoding, SQL helpers).
What we offer
Everyday Kit is a collection of small, focused utilities you can open in any modern browser. Each tool does one job well: format JSON, split a tip, merge PDFs, test a regex, convert units, and dozens of similar tasks you hit during work or study.
The site is built for speed and clarity. You should land on a tool, get your answer, and move on—without installing software or creating an account.
Privacy by design
In almost every case, your input is processed in your browser on your device. We do not upload the text you paste into tools to our servers for processing. That matters for passwords, personal notes, API tokens, and business data you would not want to send elsewhere.

Who it is for
- Students and writers checking word counts or comparing drafts
- Developers formatting JSON, decoding JWTs, or testing regular expressions
- Anyone splitting a bill, converting units, or generating a strong password
- Small teams that need quick utilities without signing up for another SaaS tool

Limitations
These tools are helpers, not professional advice. Password strength scores are heuristic. JWT decoding does not verify signatures. SQL output should be reviewed before you run it on real data. CSV parsing is basic. cURL conversion covers common flags, not every shell option.
If you need guaranteed accuracy for legal, medical, or financial decisions, use dedicated software and qualified professionals.
