What is Dice Roller?
Dice Roller is a free, browser-based tool in the Random & Fun Tools suite. Roll any number of polyhedral dice (1–6 dice, 7 side counts) with pip-rendered d6s, totals, crit detection, and a rolling history.
The headline benefit: roll 1–6 dice with d4, d6, d8, d10, d12, d20 or d100 sides.
Unlike most online tools that upload your file to a server, process it, and send it back, Dice Roller 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 dice roller?
Three reasons EasyFileKit's Dice Roller 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 Dice Roller — step by step
Here's the complete walkthrough. Everything happens instantly in your browser:
- **Step 1.** Pick how many dice to roll (1–6) using the number buttons.
- **Step 2.** Select the number of sides — d4, d6, d8, d10, d12, d20 or d100.
- **Step 3.** Click “Roll” to animate the dice and reveal each result plus the total.
- **Step 4.** Recent rolls are listed below for easy reference during your game.
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 Dice Roller
People reach for Dice Roller 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 Dice Roller, 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 Dice Roller 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 Dice Roller
Q: Which dice types are supported?
A: d4, d6, d8, d10, d12, d20 and d100 — covering the standard polyhedral set used by Dungeons & Dragons and most tabletop RPGs.
Q: Are the rolls truly random?
A: Yes. Every roll uses crypto.getRandomValues, the same secure source browsers use for cryptography. Results are uniform across the die's range.
Q: Does d6 show pips?
A: Yes — a six-sided die renders classic dot pips in a 3×3 grid. All other dice show their numeric value.
Q: What does d100 mean?
A: A percentile die that rolls a value from 1 to 100. It's commonly used together with a d10 in tabletop games to produce values like 73 or 08.
Q: Can I roll multiple dice at once?
A: Yes — between 1 and 6 dice can be rolled simultaneously, with each die shown individually and a combined total below.
Q: Does it detect critical hits?
A: Yes. Rolling a single die that lands on its maximum value (like a 20 on a d20) triggers a celebratory toast; rolling a 1 triggers a fumble alert.
Dice Roller: EasyFileKit vs server-based tools
Most "free" online tools that do what Dice Roller 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 Dice Roller does, client-side processing is strictly better for you.
Under the hood: how Dice Roller works
Dice Roller 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 Dice Roller
- **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.
