Chrome Extension
Scale recipes
on any website.
The free Chrome extension detects ingredients on any recipe page and opens them pre-loaded in Recipe Converter Pro — one click, no copy-pasting.
How it works
- 1 Install the extension
Add Recipe Converter Pro to Chrome from the Web Store. It's free, no account needed.
- 2 Navigate to any recipe
Go to Allrecipes, NYT Cooking, BBC Good Food, or any food blog. The extension works on any site that uses standard recipe markup.
- 3 Click the extension icon
Click the Recipe Converter Pro icon in your toolbar. The extension reads the ingredient list from the page automatically.
- 4 Scale instantly
The converter opens with your ingredients pre-loaded. Set your scale factor or target serving count — all quantities update at once.
What the extension includes
Reads recipe JSON-LD structured data from the page — no scraping, no fragile parsing. Works reliably across thousands of sites.
Launches Recipe Converter Pro with your ingredient list already filled in. Skip the copy-paste.
Scale by multiplier or servings, convert grams to cups, switch metric and imperial, and generate a shopping list.
Free to install, free to use, no signup, no subscription, no ads.
No data leaves your browser. Ingredients are passed directly to the converter locally — nothing is sent to any server.
Compatible with Allrecipes, NYT Cooking, BBC Good Food, Serious Eats, Food Network, King Arthur Baking, and any site using Recipe schema markup.
Why copy-pasting ingredients is slower than it looks
Most recipe websites don't format ingredient lists in a way that pastes cleanly into another tool. Amounts and unit names are embedded in prose, fractions are rendered as HTML entities, and ingredient names often include parenthetical notes or brand names. Manually transcribing a 12-ingredient recipe takes 2–4 minutes even for a fast typist — and introduces transcription errors. The extension reads the structured data that most recipe sites already embed in their pages and passes it directly to the converter, so the list arrives ready to scale with no manual input.
The structured data format (JSON-LD with Recipe schema) is used by virtually every major recipe publisher — it's what Google uses to generate rich snippets in search results. If a recipe page appears in Google with a star rating, serving size, and ingredient count in the search preview, it has the structured data the extension needs. This covers the vast majority of recipes on high-traffic sites and most individual food blogs that use standard WordPress or other recipe plugins.
Who the extension is for
The extension is most useful for cooks who regularly work from recipe websites and frequently need to scale: halving a dinner recipe for two, doubling a cookie batch for a party, converting a UK recipe's gram measurements to cups, or adjusting a standard recipe to feed a crowd. Without the extension, each of these workflows involves opening the converter separately, re-entering the ingredients, and then switching between tabs to check amounts. The extension collapses that into a single click from the recipe page you're already reading.
It's also useful when you want to save a scaled version of a recipe. Scale it in the converter, generate the adjusted ingredient list, and copy it to your notes app or recipe manager. The converter produces clean, human-readable output — not raw numbers — so the scaled list is ready to cook from immediately.
Privacy and data handling
The extension requests only the minimum permissions it needs: access to the current tab's page content when you click the extension icon. It does not run in the background, does not track browsing history, and does not collect any personal data. When you click the icon, the extension reads the recipe structured data from the active tab, encodes it as URL parameters, and opens the converter in a new tab. The ingredient data travels from your browser to your browser — it is never sent to a remote server. The extension's source code is open for inspection, and the full privacy policy is available on this page.
