About these tools

Finance, tax, health and everyday calculators that show their working. They share a small number of engines configured differently on each page — a target file size, and where a form demands it, exact pixel dimensions. The result is tuned to the specification you actually need to meet, rather than a generic "make it smaller" pass.

Processing happens on your device. Your files are never uploaded to a server, which is why there are no usage limits and no account to create.
