About ToolsFlow

ToolsFlow is a free collection of 160+ browser-based tools — calculators, converters, generators, image tools, PDF tools, and more — built to get everyday tasks done in seconds without accounts, installs, or paywalls.

Why we built it

Most online "free tools" bury a simple task behind signups, upload limits, or watermarks on the output. We wanted the opposite: open a page, do the task, get the result — nothing else in the way. Every tool on ToolsFlow runs entirely in your browser using client-side JavaScript, so there's no server processing your files and no account to create.

How it works

Each tool is a self-contained page. When you use a calculator, converter, or file tool, the computation happens on your own device using your browser's built-in capabilities — nothing you type or upload is transmitted to a server. This is also why ToolsFlow tools tend to be fast: there's no round trip to wait on.

What you'll find here

• Calculators — age, percentage, interest, BMI, and more
• Converters — file format, unit, and currency conversions
• Generators — passwords, QR codes, and other everyday generators
• File & PDF tools — merge, split, compress, edit, and convert
• Image tools — resize, convert, and edit images in-browser

Our approach

We add new tools regularly based on genuinely common tasks people search for. If there's a tool you'd like to see, reach out — we read every message.
