Useful tools, one job each.

Fourteen categories, from percentages to invoices and material estimates. Each tool finishes one job.

There is no account to create. Log in on this site is a preview, and it does not save anything.

Calculations run in your browser. Image tools redraw a picture on this device and offer a download. Those files are not uploaded.

Most results use only the figures you type. The crypto scanner is the exception: it reads public market data and shows when that data was fetched. Fee tools start from rates you can edit.

Tax, health, building, and price figures are estimates from the formula on the page. They are not advice, a quote, a diagnosis, or a promise of a future price.

• Calculators — Percentages, loans, pay, and other everyday maths. Enter the numbers and read the result.
• Developer Tools — Format, convert, and generate text in the browser. Paste, edit, and copy.
• Files & Media — Compress, convert, merge, sign, and clean up files in the browser. Your files stay on your device.
• Design & Creative — Palettes, contrast, gradients, and CSS you can preview and copy.
• Data Visualization — Paste a table and export a chart. Funnels, Gantt, bars, lines, pies, and simple diagrams.
• Business Tools — Invoices, quotes, fees, and margins from the numbers you enter.
• Home & Trade — Paint, concrete, tiles, and material quantities from measurements you already have.
• People & Teams — Meetings, roles, and a short work-style quiz for working together.
• Text Tools — Count, convert, clean, and compare text in the browser.
• Everyday & Fun — Timers, pickers, dice, and other small helpers.
• Gaming & Hardware — Hardware testers, and calculators for the number a player needs.
• Crypto — Profit, position size, and staking from numbers you type. The scanner shows its source and time. No wallet.
• Creator Tools — Rate cards, engagement, and posting windows. Starting points, not a promise of reach or income.
• AI Tools — Token counts and cost estimates from published prices, with the date those prices were checked.
