# Scale Any Recipe to Any Serving Count

> Paste recipe text, drop a screenshot, or photograph a cookbook page — ingredients are parsed with their amounts and re-portioned to whatever serving count you need. Rounding is kitchen-real: cups land on eighths, eggs stay whole, "2.67 eggs" never happens. Flip every amount between metric and US, and when you're missing an ingredient, the built-in substitution table offers the standard swap. Copy the result as a clean recipe card.

## How it works

1. **Get the recipe in** — Paste the text, drop a screenshot, or take a photo of the cookbook page. Ingredient lines are detected automatically.
2. **Set the servings** — Tell it what the recipe serves and what you need — or use the half/double buttons. Every amount re-portions with sensible rounding.
3. **Adapt and take it to the kitchen** — Flip units between metric and US, check the swap for any ingredient you're missing, then copy the scaled recipe card or print it.

## FAQ

### How does the rounding work?

Like a cook, not a calculator. Cups and spoons round to eighths, eggs round to whole eggs, metric grams round to sensible figures. Scaling a 4-serving recipe to 6 gives you "1 ½ cups", never "1.4999 cups".

### What can it substitute?

The built-in table covers the classic baking and cooking swaps — buttermilk, eggs, brown sugar, cake flour, baking powder, heavy cream, fresh herbs, wine, and about twenty more. Tap the swap icon next to a matched ingredient to see the ratio.

### Does the photo import work on handwriting?

Printed cookbook pages and screenshots work well. Handwriting is hit-or-miss — paste the text instead when you can.

### Can it scale by pan size?

Not yet — serving count and direct multipliers only. Pan-area scaling is on the list.

## Tips

- **Eggs stay whole** — Scaling math respects the kitchen — eggs round to whole eggs, spoons to eighths. Trust the card, not a calculator.
- **Missing something? Check the swap** — Ingredients with a known substitution show a swap icon — buttermilk, cake flour, fresh herbs, wine, and more.
- **Screenshots parse too** — A recipe site screenshot or cookbook photo works — OCR runs on your device. For handwriting, paste the text.

## Privacy — what we do not do

This tool runs entirely in the browser via WebAssembly. Your file never reaches a Loft Tools server. Specifically:

- **No upload.** The file bytes load into the browser tab's memory and process on your own CPU. Open DevTools → Network and observe zero outbound requests carrying file data while Scale Any Recipe to Any Serving Count runs.
- **No AI training on your file.** Loft does not train models. We could not train on a file we cannot see.
- **No content scanning.** No virus, copyright, or content-moderation pass against your file. The bytes are not accessible to us.
- **No server-side log of file contents, filenames, or EXIF metadata.** Cloudflare edge captures URL and truncated IP for abuse defense (standard CDN behaviour). Cloudflare Web Analytics records anonymous page hits, no cookies, no PII. Nothing about your file content reaches any log.
- **No retention.** Close the tab and the file leaves browser memory. No backups exist on our side because no copy ever existed on our side.
- **No account.** No email, no signup, no auth, no telemetry tied to you.
- **Offline-capable after first visit** (PWA). Once you've loaded a tool, it caches; later sessions work without internet. For high-sensitivity files, run the tool once online to warm the cache, then disconnect before processing.

Compare with upload-based services: each transmits your file to a processing server. Even over HTTPS, each has logs, retention windows, and subpoena exposure. Loft has none of these because the server architecture does not include your file.
