Twinprice - Currency Converter for Every Page от Krlo

See shop prices in your own currency, right beside the original. 160+ currencies. Page content never leaves your browser.

See what a foreign price costs in your own money, right where the price sits on the page, next to the original.

Open a shop that uses another currency and Twinprice finds the prices, offers to convert them, and shows you the rate before you accept. Each converted value appears beside the original, so you always see what the shop actually charges.

WHY IT ASKS TO READ AND CHANGE DATA ON ALL WEBSITES
A price can be on any shop, so Twinprice has to look at the pages you open to notice one. It only reads them on your device. Page content, prices and the sites you visit never leave your browser. The only thing sent anywhere is a three-letter currency code such as EUR, to fetch that day's reference rate. No ads, no analytics, no tracking. The code is open source under the MIT licence.

WHAT YOU CAN CONVERT
- Every price on a page, in one click
- One price you highlight
- Any amount you type into the popup

CURRENCIES
- Over 160 currencies to convert into, searchable by code or name
- 50 currencies detected automatically from the page
- Correct formats, including yen with no decimals and dinar with three

MADE FOR REAL SHOPS
- Handles tricky price layouts, with fixes for shops such as Allegro, Digitec, Trendyol and tap.az
- Picks up prices that load later on modern shop pages
- Mark the shops you use most to convert automatically
- Undo puts the page back exactly as it was
- Keyboard shortcut: Ctrl+Shift+Y (Command+Shift+Y on Mac)

ABOUT THE RATES
Reference rates come from Frankfurter, which publishes European Central Bank rates every working day. They are for comparing prices. They are not the rate your bank or card will charge, and they don't include fees.

LIMITS
Prices inside images and some embedded frames can't be converted. On unusual layouts you may need to choose the source currency yourself.

Free, no account needed. Available for Chrome and Firefox, including Firefox for Android.
