Every tool listed here was opened and used before being added. Each review covers what the tool actually does, how to use it step by step, what the free plan really includes — including resolution caps and daily limits that marketing pages tend to bury — and where it falls short.
Two of the tools are our own: PicCalc for local, private image editing, and CalcHub for mortgage, APR and currency calculations. Both are marked clearly wherever they appear.
All other links point to third-party sites. We are not affiliated with them, and their free quotas and pricing change often — always confirm current terms on the official site.
