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.

Are the calculators free to use?

Yes. No account, no trial, no watermark and no cap on how many files you process. Every setting is available to everyone.

Do my files get uploaded?

No. These tools run entirely in your browser, so the file never leaves your device. You can confirm it in your browser’s Network tab, or by disconnecting from the internet once the page has loaded — the tools keep working.

Do I need to install anything?
