One extension. A new format.

Name: MediaShift
Author: Hybris Studio SRL

Convert photos, videos and audio files directly in Finder: in a watched folder, simply rename their extension and MediaShift converts their content on your Mac. Image to image, video to video or audio to audio: each file stays within its category.

RENAME. CONVERTED.

Watch a folder

In Folders, add a test folder. Subfolders are included. Wait a moment after adding a file, then rename its extension in Finder, for example photo.png → photo.jpg. Keep the app open and watching active. Renames while paused or closed and moves between folders do not trigger conversion. Keeping an original copy is off by default; enable it in General to keep a copy. When enabled, unique names avoid overwriting files.

Rename the extension

Right-click → Rename → replace .heic with .jpeg → confirm.

Let MediaShift convert

Keep MediaShift open and watching active. Outside watched folders, renaming does not convert a file.

A familiar interface. In your language.

General lets you choose a language and a light, dark or system appearance. Changes apply immediately and are saved. System language is used by default, with English as fallback. Image, audio and video tabs control output quality. Activity shows the last 30 conversions of the current session. Quit is unavailable during conversion or while jobs are queued.

Updates

Enabled by default: checks at launch, then every 4 hours while the app is running.

Installation

Drag MediaShift.app into Applications, then open it from Applications. Requires macOS 13 or later and an Apple Silicon Mac. The app appears in the menu bar. Closing Settings keeps it running; Quit stops folder watching.

First launch: macOS approval

This app is not signed with an Apple Developer ID or notarized. If macOS blocks it, first try opening it, then go to System Settings → Privacy & Security → Open Anyway. Only proceed if you trust its source. Do not disable macOS security protections.

Finder

Disabling Finder confirmation is a global, persistent setting for every Finder file, even when MediaShift is closed. Outside watched folders, changing an extension does not convert content. You can restore confirmation in General. Unsupported conversions are rejected; the original name is restored only when safe. If restoration fails, check the filename, extension and folder permissions in Finder. No protection is guaranteed for very fast renames or files modified at the same time.
