How to use Tournament Bracket Maker in 3 simple steps

Open the Tournament Bracket Maker workbench
Open the workspace in your browser. The code it needs loads with the page — there is nothing to install and no account to create.
Provide your input files or parameters

Save your output
Preview the result and click download. The file is written from the page straight to your disk; nothing is stored on a server.
Local Browser Compute vs. Traditional Cloud Converters
What changes when the tool runs in your own tab instead of on someone else's server.
| Feature / Aspect | OpenTools (Local) | Standard Cloud Converters |
|---|---|---|
| Where your file goes | Stays in the page; it never touches a server | Uploaded to and processed on the provider’s servers |
| Waiting to upload | None — there is no upload step | Upload time, then a place in the server queue |
| Price | Free, with no paywall and no sign-up | Often a free tier with daily limits or a subscription |
| Retention | Nothing to retain; the file was never sent | Stored on the provider’s disks under their policy |
| Account & tracking | No account, no third-party trackers, no client-side analytics | Often an email sign-up and advertising trackers |

Frequently Asked Questions
Does Tournament Bracket Maker upload my files or data to any server?
No. The work happens in the page you have open. This page is served with a Content Security Policy of connect-src 'none', so the browser will not let it open a network connection at all.
Is Tournament Bracket Maker free?
Yes. There is no paywall, no usage limit and no account. If the tool is useful to you, you can choose to support the project.
Can I use this for confidential legal or financial records?
Your file is not sent anywhere, so it is not exposed to this site or to a third party. What remains is your own device and browser — treat it the way your organisation's policy treats any local file.
Does the site collect anything when I visit?
The server records one coarse metadata event per page visit (see the security policy for exactly what). There are no third-party trackers and no client-side analytics, and nothing from the tool itself — your files, inputs or results — is included.
