ToolExo

ToolExo is a free, no-signup hub of online calculators and everyday utility tools for students, small-business owners, marketers, developers, and anyone who needs a quick calculation or file conversion.

It helps you handle percentages and math, business and finance, SEO and text utilities, PDF and image tasks, and common developer workflows right in your browser. Every tool runs locally with a privacy-first, ad-free experience - no account required.

What's inside

• Free online calculators for percentages, math, business, and finance
• SEO and text utilities (word count, case conversion, metadata checks)
• PDF and image tools (merge, compress, resize, metadata removal)
• Developer helpers and everyday browser workflows
• Growing categorized tool library with practical guides

Each tool shows the method behind the result, so you can check the inputs, understand the assumptions and limits, and move on with confidence. Built as a one-person side project. I'd love feedback on which everyday tool should be clearer or more trustworthy, and which category to expand next.
