Every tool you need,
completely free

ScoutMyTool is a browser-first suite of 2300+ free calculators, PDF utilities, document templates, and unit converters. The site is built and maintained by the ScoutMyTool editorial team as a public-benefit project — every tool is free forever, with no signup, no watermarks, no per-file limits, and no paywalls. The mission is straightforward: the internet\u2019s best online tools should not be locked behind a subscription or gated by an account.

Every formula on the site is verified against an authoritative source before it ships. Health calculators cite the World Health Organization (Technical Report Series 894 for BMI), the Centers for Disease Control (growth charts for pediatric BMI), and the American Heart Association 2017 hypertension guideline. Finance calculators cite the IRS (Rev. Proc. 2025-32 for 2026 tax brackets), the Consumer Financial Protection Bureau (Regulation Z for loan APR calculation), and the SEC (compound-interest reference). Every top calculator page walks through the underlying formula with a worked example, so a reader can verify our math against the source.

Privacy is a first-class design constraint. PDF tools that can run in the browser — merging, splitting, watermarking, page rotation, cropping — process files entirely on your device via WebAssembly, so your documents never leave your computer. Tools that require server-side processing (OCR, high-quality PDF-to-Word conversion) delete uploaded files immediately after the download link is generated. There is no telemetry on tool usage inputs, no data sales to third parties, and no advertising retargeting based on your file contents.

The site launched in early 2026 and grew to over 2,300 tools across finance, health, PDF, document templates, image utilities, and unit converters through steady daily development. The complete tool catalog, our methodology, and our approach to formula verification are documented on the methodology page. Find the tool you need below.
