Cooking Converter — Free Online Tool (No Upload, Private)

Convert cups, tbsp, tsp, ml, fl oz, liters and grams (water-based).

What is Cooking Converter?

Cooking Converter is a free, browser-based tool in the Unit & Data Converters suite. Convert cooking measurements between volume units (ml, L, US/metric cups, tablespoons, teaspoons, fluid ounces, pints) and water-equivalent grams. Swap with one click.

The headline benefit: convert cups, tbsp, tsp, ml, fl oz, liters and grams (water-based).

Unlike most online tools that upload your file to a server, process it, and send it back, Cooking Converter runs entirely in your browser. Open DevTools → Network while using it and you'll see zero file-upload requests — only static assets (JavaScript, CSS, fonts) load. Your data never leaves your device.

Why use this cooking converter?

Three reasons EasyFileKit's Cooking Converter stands out from the crowd:

- **Private by design** — all processing happens locally via JavaScript and WebAssembly. No server ever sees your input.

- **Instant** — no upload wait, no queue, no server round-trip. Results appear the moment you act.

- **Free & unlimited** — no accounts, no watermarks, no daily caps. Use it as many times as you like.

How to use Cooking Converter — step by step

Here's the complete walkthrough. Everything happens instantly in your browser:

- **Step 1.** Enter the amount you want to convert.

- **Step 2.** Pick the source unit (cup, tbsp, tsp, ml, L, fl oz, pint, gram, kg).

- **Step 3.** Pick the target unit.

- **Step 4.** Use the swap button to reverse the conversion.

That's it. No sign-up, no upload bar, no waiting. If something doesn't work as expected, check the FAQ below.

Common use cases for Cooking Converter

People reach for Cooking Converter in a few recurring situations:

- When you need the result **now** and can't wait for a server-based tool to upload, queue, and process your file.

- When your file is **private or sensitive** — financial documents, personal photos, medical PDFs — and you don't want it travelling across the internet.

- When you're on a **slow or metered connection** — uploading a 50 MB file just to compress it makes no sense when the same work can happen locally.

- When you've hit the **daily limit or paywall** on another "free" tool site.

Privacy: what actually happens to your data

This is the single most important point about Cooking Converter, so it deserves its own section.

When you use this tool, your input is processed by JavaScript running in your browser tab. The code is downloaded once (cached afterwards) and executes locally on your CPU. At no point is your file, your text, or your input data transmitted to any server.

You can verify this yourself in under 30 seconds:

- Open Cooking Converter in your browser.

- Press F12 to open DevTools.

- Switch to the Network tab and tick "Disable cache".

- Use the tool — drop a file, type text, whatever the tool needs.

- Watch the Network log. You'll see only static assets (JS, CSS, fonts, icons). No request contains your data.

This isn't a setting you toggle or a promise in a privacy policy — it's how the tool is architecturally built. There is no upload endpoint to call.

Frequently asked questions about Cooking Converter

Q: Why are there US and metric versions of cups and spoons?

A: A US cup is 240 ml, a metric cup is 250 ml. A US tablespoon is ~14.79 ml while an Australian one is 20 ml. Pick the one matching your recipe's origin.


Q: How are grams handled?

A: Grams are converted assuming water density (1 ml = 1 g). For flour, sugar, oil etc. the conversion will be off — weigh ingredients on a kitchen scale for precision baking.


Q: What's a fluid ounce?

A: A US fluid ounce is ~29.57 ml. A UK (imperial) fluid ounce is ~28.41 ml. The tool includes both.


Q: Are the factors exact?

A: Yes for the defined units (1 US fl oz = 29.5735295625 ml exactly, 1 US gal = 3.785411784 L exactly, etc.). The gram conversion is exact for water only.


Q: Is anything uploaded?

A: No — all conversion is local to your browser.


Cooking Converter: EasyFileKit vs server-based tools

Most "free" online tools that do what Cooking Converter does follow the same model: you upload your file to their server, they process it with a backend script, then they send the result back. Here's the honest comparison:

| | EasyFileKit | Server-based tools |

|---|---|---|

| **Your file leaves your device?** | Never | Yes, uploaded to a server |

| **Speed** | Instant (no upload) | Slower (upload + queue + download) |

| **Privacy** | Complete | Your file is on someone else's computer |

| **Cost** | Free, unlimited | Often capped or "premium" gated |

| **Works offline** | Yes (PWA) | No |

Server-based tools aren't evil — they exist because some tasks genuinely need heavy backend compute. But for everything Cooking Converter does, client-side processing is strictly better for you.

Under the hood: how Cooking Converter works

Cooking Converter is built with modern browser APIs. Depending on what it does, it may use:

- **Canvas API** — for image manipulation (pixel-level access, filters, resizing).

- **Web Crypto API** — native, hardware-accelerated cryptography (AES-GCM, SHA-256, PBKDF2) for any encryption or hashing.

- **pdf-lib / pdf.js** — fully client-side PDF creation and rendering.

- **MediaRecorder API** — for capturing screen, audio, and video.

- **WebAssembly** — for heavy codecs (image compression, media processing).

All of these run inside your browser's sandbox. They cannot access your filesystem (beyond files you explicitly choose), cannot make network requests with your data, and cannot run persistently in the background.

Pro tips for getting the most out of Cooking Converter

- **Bookmark the tool** — it works offline once cached, so you can use it even without a connection.

- **Install EasyFileKit as a PWA** — open the browser menu and choose "Install app" for a standalone window and offline access.

- **Use it on mobile** — every tool is fully responsive and works on phones and tablets, not just desktops.

- **No file size anxiety** — because nothing uploads, you can process large files that server-based tools would reject or charge for.
