All tools

All free tools in one place

This page lists every tool on adigitools.com, grouped by category. Use it as a directory when you know what you want to do but not where to find it. Each tool opens on its own page with a working tool, step-by-step instructions and a guide that explains how to interpret the results. All tools are free, work in modern browsers on phones and computers and need no registration.

How to choose the right tool

Start with the job you are trying to finish rather than the tool name. If you need to prepare pictures for a website or listing, look in image tools. If you need to bill a client, plan a project or work out what to charge, look in business tools. If you need to understand whether marketing is profitable, use the marketing calculators. If you need to check a website, a password or an internet connection, open the web security tools. Sellers will find helpers for Etsy and Amazon KDP, and anyone handling agreements will find the contract tools.
