Coinmill review
A free web converter with broad asset coverage and useful tools for publishers.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
Coinmill is a free, browser-based currency converter for people who need quick conversions across a broad selection of fiat currencies, cryptocurrencies, metals and other units. Users choose source and target currencies, enter an amount, and receive a current conversion. The service also suits website owners who want to add conversion forms, rates, converted prices or feeds to their own pages. Its fit is strongest for solo users and small organizations that need a web tool rather than a full financial data platform.
The calculator combines practical options with a publisher-oriented ecosystem. Rates are downloaded to the page, while calculations run locally in the browser after that download. A text calculator accepts natural-language conversion entries, and users can choose rounding to the smallest currency unit or leave results unrounded. Printable exchange-rate tables support reference and reporting tasks. For websites, Coinmill supplies embeddable JavaScript currency rates and conversion forms, website price-conversion tools, and currency RSS feeds. These features make it more useful than a basic one-off converter when conversion needs must appear in content or web workflows.
Coinmill’s free model keeps access straightforward, but its scope remains centered on browser use. There are no mobile apps, so people who need a dedicated phone experience should consider another option. Historical-rate verification is also not part of the stated offering, which limits suitability for users analyzing past exchange movements or requiring an auditable rate history. Choose Coinmill for accessible web conversion, broad asset coverage and embedding options; choose an alternative when native mobile access or verified historical data is essential.
