What It Is

Currency.Wiki is an online currency tool operated by CurrencyWiki Technologies LLC. Its core features include real-time exchange-rate conversion, popular currency pairs, historical exchange-rate charts, financial news, a currency encyclopedia, and Chrome/Firefox browser extensions. It supports 170+ currencies and Bitcoin, and emphasizes that basic currency conversion is always free.

Core Features and Developer Perspective

Feature-wise, it is more than a simple converter. It offers up to 15 years of historical exchange rates, CSV/HTML/TXT export, price alerts, conversion cards, in-page price detection, AI Smart Scan, and Document Converter. AI Smart Scan can identify products and prices on web pages, while Document Converter can process PDF, PNG, JPG, TIFF, WebP, and other files, outputting formats such as CSV, XLSX, QBO, and JSON. It can also translate 70+ languages. Ecosystem integrations include Google Sign-In, Google Gemini AI, Stripe, Google Drive, Dropbox, Box, plus Chrome Extension and Firefox Add-on.

However, by “developer tool” standards, the reviewed text does not disclose a public API, SDK, webhook, or sample code. Its terms also explicitly prohibit scraping exchange-rate data without permission, automated access, or using the service to build competing products. As a result, it is better suited to end users and lightweight operational workflows than to serving as a backend exchange-rate data source.

Pricing and Limits

Basic conversion is free to use. Premium features are split into Web Pro, Extension Pro, and Document Converter Pro, with monthly and annual billing options; annual plans include a 3-day trial. AI Smart Scan and document conversion also have separate credit packs. Payments are processed by Stripe and priced in USD, but the reviewed text does not provide specific amounts. Subscriptions can be canceled, and fees after the trial are generally non-refundable.

Pros, Cons, and Who It’s For

Its strengths are ease of use, broad currency coverage, long historical-data range, comprehensive export and cloud-save options, and a privacy policy that states original uploaded files are deleted after processing. Its drawbacks are that exchange rates are for reference only, AI recognition accuracy is not guaranteed, premium features depend on services such as Google, Stripe, and Gemini, and there is no developer API information.

It is suitable for travelers, cross-border shoppers, business users, operations staff, or finance assistants who need exchange-rate lookup and document organization. It is not ideal for engineering teams that require SLAs, compliance-grade exchange-rate sources, programmable APIs, or self-hosted deployment.

Access from China

The reviewed text does not provide information on accessibility from mainland China, payment availability, or localization. Given its reliance on services such as Google Sign-In, Gemini, Stripe, and Dropbox, use in China may be affected by the local network and payment environment, though actual connectivity cannot be determined from the text alone. Alternatives include XE, Wise, OANDA, Google Finance, as well as developer-oriented services such as ExchangeRate-API, Fixer, and Open Exchange Rates.
