About Mini-Tools.uk

Practical calculators and browser tools for everyday tasks.

Mini-Tools.uk is a collection of focused utility pages for finance, development, images, PDFs, text and privacy-related tasks. The goal is simple: make each page useful, clear and quick to understand.

Focused tools Each page is designed around one practical task instead of a crowded dashboard.
Clear assumptions Calculators explain what they include, what they exclude and when results are only estimates.
Browser-first design Many tools run locally in the browser when the task does not need remote processing.

What Mini-Tools.uk is

Mini-Tools.uk publishes small, practical tools for people who need quick answers or simple browser utilities. Some pages provide UK calculator estimates, while others support developer, image, PDF, text, security and privacy tasks.

The site is built around ordinary use cases: checking a salary estimate, formatting JSON, compressing an image, comparing text, generating a secure password, or estimating the cost of an AI API call.

A good tool page should be easy to open, easy to understand and clear about how the result is produced.

How pages are designed

Mini-Tools.uk keeps navigation, wording and assumptions consistent while allowing each tool to use the layout best suited to its task.

Purpose Make the main task obvious within a few seconds.
Privacy Use browser-side processing when the task allows it.
Limits Explain what a tool covers and what it does not cover.
Clarity Avoid unnecessary visual clutter and confusing wording.

How Mini-Tools.uk approaches privacy

Privacy depends on what a page actually does. A JSON formatter, password generator or image compressor can often run inside the browser. A hosted image-sharing tool, by contrast, needs a remote service so the file can be stored and shared.

That is why each tool should describe its behaviour in plain language. Local-only pages should say that processing happens in the browser. Upload or sharing pages should explain when a file is sent to a service.

What kinds of tools are on the site

  • UK calculators, including tax, VAT, mortgage, stamp duty, IR35 and dividend planning tools.
  • Developer tools, including JSON formatting, text diff checking and AI token cost estimation.
  • Image and PDF tools, including image resizing, compression, color picking and PDF conversion helpers.
  • Security & Privacy Tools, including a browser-side password generator.

Are the tools free to use?

The public tools on Mini-Tools.uk are available to use in the browser. Some features may depend on browser capabilities, file size or third-party service limits.

Which tools send data to a server?

Browser-only tools keep files on your device. Image hosting uploads a file so you can copy a public link. Each tool page explains what leaves the browser.

Can I suggest a new tool?

Yes. Send the suggestion by email and include the task, expected input, expected output and any examples that would make the tool easier to design.
