Paste an ingredient list, set how many servings the recipe currently makes and how many you want, and this tool rescales every line for you. It reads the number at the start of each ingredient, including fractions like 1/2 and mixed numbers like 1 1/2, then multiplies by the scale factor and rewrites the amount cleanly. You can also just type a plain multiplier such as 2 to double or 0.5 to halve. Scaling a recipe by hand is where mistakes creep in, especially with awkward fractions and larger batches, so letting the numbers update automatically keeps your ratios correct. Everything runs locally in your browser, nothing is uploaded, and the result is ready to copy straight into your notes or a shopping list.
