Disclosure: agathox makes some of the tools listed here. They are labelled and scored by the same method as every other tool.
Ranked by signals we can measure or quote: website health, the facts each tool's own pages state, and community discussion. Nothing here has been hands-on tested yet, so this is not a quality test. How the signals rank works

- Where files go
- Calculations are processed locally in the user's browser using JavaScript. The page says: “Calculations are processed locally in your browser using JavaScript, so the webpage does not need to interact with a server.”
From the tool's own pages, checked 2026-11-04. Sources: Home. Prices and limits change; check the tool before you rely on them.
Read automatically by a program, not by a person. Each fact quotes the sentence it came from, and a fact is shown only if that sentence is on the page. Where a page did not say, it reads “Not stated.”
