About ByToolHub
A collection of small, fast tools that do one job well and keep your data on your own machine.
Most online utilities ask you to upload something before they will help you. For a JSON payload from a production system, a photo from your phone, or a token from a live session, that is a poor trade. These tools make it unnecessary: the work happens in the page you are already looking at.
Your data stays with you
With one exception, every tool runs in your browser. Text you paste, files you drop and passwords you generate are processed on your device and never sent to a server. The exception is the Open Graph checker, which has to fetch the page you name — a browser is not allowed to read another site's HTML directly.
It works without a connection
Once a tool page has loaded, every tool except the Open Graph checker keeps working offline. That is a side effect of doing the work locally rather than a feature bolted on, and it is the simplest proof that nothing is being uploaded.
No accounts, no limits
There is nothing to sign up for, no usage cap and no watermark on anything you produce. If a tool is here, it works fully on the first visit.
What's here
15 tools across 5 areas, each with a guide explaining the background rather than just the buttons.
- Developer — Inspect and debug the formats you work in every day.
- Encoding & Conversion — Move data between representations without losing anything.
- Security & Identity — Hashes, tokens, passwords and identifiers.
- Images & Design — Prepare images, colour and codes for the real world.
- Text & Writing — Count, measure and reshape written text.
How it works
The site is a Next.js application. Every page is prerendered to plain HTML at build time, and the tools themselves are JavaScript that runs on your device using standard browser APIs — the Web Crypto API for hashing and passwords, a canvas for image work, the platform's own parsers for everything else. There is no database, no account system and no analytics on your input.
There is exactly one server endpoint, and it exists for the Open Graph checker: it fetches the single public address you give it, reads the page's meta tags and returns them. It refuses private and internal addresses, gives up after a few seconds, and stores nothing. The privacy policy describes it in full.
The site does show ads, which is what pays for it. Ads are supplied by a third party and, like any ad network, they use cookies — that is separate from the tools themselves, which never transmit what you type.
Who builds it
ByToolHub is built and maintained by Abdul Samad, a web developer who kept reaching for small utilities like these and got tired of pasting work data into sites that upload it. Every tool, and every guide that goes with it, is written and tested by hand. Corrections and suggestions go straight to the same person through the contact page.
Suggest a tool
The list grows based on what people ask for. If something you need is missing, or a tool here is close but not quite right, say so — it is the most useful thing you can send.
