Your files stay
on your machine

Most online converters upload your files to a server and store them — sometimes indefinitely. FileConverter does the opposite.

Zero network access

No telemetry, no analytics, no pinging home. Works identically with Wi-Fi off. Contracts, health records, financials — nothing leaves your disk.

No account, no tracking

No sign-up, no licence key, no email. FileConverter doesn't know who you are or what you convert. It's a tool, not a service.

Open source engines

Powered by ffmpeg, pandoc, ImageMagick, and LibreOffice — audited by millions of developers. No proprietary black box processes your data.

Three steps.
Zero friction.

Install once, forget about it. FileConverter lives in your menu bar and is always one right-click away.

01

Launch once

Open FileConverter and it settles into your menu bar. It registers as a Login Item so it's ready on every restart — automatically.

02

Right-click any file

In Finder, right-click any supported file. "Convert to…" appears in the context menu. Hover to see every valid output format.

03

Watch the badge

A spinning badge appears on the file while it converts. A green checkmark confirms success. The new file lands right next to the original.

04

Nothing leaves your Mac

Conversions run through locally installed tools — ffmpeg, pandoc, ImageMagick. No network request is ever made.
