Free Tools

Tools I built to make the work faster.

Beyond the edit, I vibe-code small media utilities to remove the friction from everyday production work. They all run 100% on your own device: no accounts, no uploads, nothing sent to a server.

Why local

Private by design.

The same principle behind good post: keep control of your files. These tools do the work on your hardware, not in someone else's cloud.

On-device

Your files stay yours

Conversions run in your browser; downloads run in a local process. Nothing uploads.

No accounts

Nothing to sign up for

No logins, no telemetry, no paywalls. Open it and use it.

Practical

Built for real delivery

Presets and formats that match the platforms and limits you actually ship to.

Open

Yours to run

The downloader ships as source you can read and run yourself. No black box.
