Make it local

Choose defaults for supported calculators. You can mix a region, units and currency.

Changing units converts supported measurements. Changing currency relabels amounts; it does not exchange money. Tax rules, tariffs and broker rates remain your inputs.

Only these preferences are saved in this browser. Calculator inputs are not saved.

Small tools. A little more time.

Made for everyday work

ToolMallow brings free tools and calculators together in one calm workspace. Prepare an image, organize a PDF, clean up a CSV export, or work through a calculation. The catalog is organized by task, with compact categories, search, favorites, and recently used tools.

Useful before everything else

Every tool has a specific job, practical instructions, and an explanation of its limits. Related tools and guides help you move to the next step without searching the web again. There is no subscription or account required to use the tools.

Local processing

File processing and calculations happen on your device. The website serves the application code; the tool does not upload your files to a conversion server. Larger file tools load their engines only when needed. Device memory and browser support affect the sizes they can handle.

Built to grow carefully

New tools belong in the existing catalog, with clear categories and useful guides. We favor a tested capability over a page that merely repeats a search phrase. Suggest something useful through Contact.

Health and financial estimates

These calculators explain their assumptions and cite relevant sources. They do not replace clinical assessment, financial advice, or the terms of an actual product. ToolMallow does not claim independent medical review.
