Currency Converter

Instantly convert prices on any webpage to your preferred currency — no copy-pasting, no switching tabs.

How it works
Click the toolbar button or right-click to toggle conversion on and off. All prices with recognized currency symbols (€, $, £, ¥, kr, and many more) are highlighted in yellow with the converted value shown inline. Hover over any converted price to see the original value, exchange rate, and timestamp. A built-in calculator in the toolbar popup lets you convert any amount manually.

Features
-Converts prices in text automatically on page toggle
-Handles split-rendered prices (e.g. Amazon's superscript cent format)
-Automatically picks up newly loaded prices as you scroll (lazy-loaded content)
-Right-click any selected text to convert just that selection
-Supports Latin, Cyrillic, Arabic, Japanese, Korean, Thai, Hebrew, Greek and other script currency symbols and names, including spelled-out names (Euro, Yen, Pound, etc.)
-OCR conversion for prices embedded in images, including photos in Yelp restaurant listings
-Automatically restricts image OCR to the active lightbox/modal when one is open
-Built-in calculator in the toolbar popup for quick manual conversions

Limitations
