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 help with UK finance estimates, while others support developer, image, PDF, text and security 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

The site is being improved page by page so that navigation, layout, wording and assumptions stay consistent. The goal is not to make every page look identical, but to make every page feel familiar and dependable.

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 finance 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.
  • Privacy and security helpers, including a browser-side password generator.

Contact and feedback

Mini-Tools.uk is still evolving. Feedback is useful when a page is confusing, a calculation needs clearer assumptions, a tool has a broken flow, or a feature could be explained better.

Are all 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.

Do all tools process data locally?

No. Many tools run locally, but features that create hosted files or shared links may need a remote service. Each tool should explain its own behaviour.

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.
