Paste a recipe and resize it by multiplier or servings — fractions handled, unreadable lines flagged not guessed, with copy and PDF export.
Resizing a recipe is just multiplication: pick a factor (2 to double, 0.5 to halve) or enter your original and desired servings, and every quantity scales by the same ratio.
This tool reads common formats — whole numbers, decimals, fractions like 1 1/2, unicode ½, and ranges like 1–2 — and rewrites each line with cooking-friendly fractions.
Lines without a clear quantity (“a pinch of nutmeg”, “salt to taste”, or an instruction line) are passed through unchanged and flagged, rather than guessed at — a confidently wrong number is worse than an honest “adjust this one yourself.” Also note that some things don't scale linearly: baking time, pan size, and leavening at large multiples all need judgement, not just arithmetic. For pans, use the pan size converter.
