Convert supported files without uploading them.

FileConverter is a focused macOS desktop app. It inspects files locally, shows only eligible output choices, validates results, and keeps the original untouched. Download the Apple silicon build for macOS 26.5.2+ or the Intel build for macOS 14+.

No account to tryNo subscriptionNo file uploads

Download free and prove it works for your files.

Free mode includes your first 10 successfully completed source-file conversions, then 1 successful conversion each local calendar day. Failed, cancelled, refused, corrupt, or invalid jobs use none of the allowance.

Apple silicon and Intel Mac builds are available now. The Windows build is coming later.

Private and local

Conversion runs on your computer. Source files and outputs are never uploaded to Nunuworks.

Careful output handling

FileConverter validates completed output before publishing it and never silently overwrites an existing file.

One honest app

The same signed application works in free and paid mode. Purchase changes the allowance, not quality or formats.

One payment, every update we release.

Nunuworks will keep improving FileConverter and send updates whenever possible. Every FileConverter update Nunuworks releases is included at no extra charge.

This does not promise a particular feature, release date, maintenance period, or compatibility with every future operating system or device. Your signed keys do not expire and do not require a recurring license check.

Nunuworks uses this address only to look for an eligible purchase and deliver its existing keys. See the FileConverter Privacy Policy.
