What ToolWorld is
ToolWorld is a set of 100 small web tools — calculators, text utilities, developer tools, image tools, document utilities, date and time tools, unit converters and generators. Each tool is built to do one job well: open the page, use the tool, get your answer.
Why it exists
A lot of everyday tasks — checking a percentage, resizing an image, formatting a block of JSON, converting a unit — don't need a heavyweight app or a sign-up form. ToolWorld was built to give each of those tasks a clean, dedicated page that loads quickly and works the same way every time.
Privacy-first, browser-based tools
Wherever practical, tools on ToolWorld process your input directly in your browser using JavaScript. Text, files and images generally aren't uploaded to a server — the calculation, formatting or conversion happens on your own device. Individual tool pages note this explicitly, and any exception is called out on that tool's page.
What you can do here
- Run quick calculations without opening a spreadsheet
- Clean up, count or reshape blocks of text
- Format, minify or decode common developer formats
- Resize, compress or convert images locally
- Convert between everyday units and time zones
- Generate passwords, QR codes, colors and placeholder content
What's next
ToolWorld is actively maintained, and new tools are added over time based on what people actually search for and ask about. If there's a tool you'd like to see, the contact page is the best way to suggest it.
