Images and video, compressed with settings you control. Export browser-ready formats, strip metadata, and cut mobile crops — all from one native macOS utility powered by FFmpeg.
// Features
A lightweight native macOS utility for developers and creators shipping media to the web.
Output JPEG, PNG, WebP, or AVIF with a quality slider, optional max width, metadata stripping, and an extra WebP copy for modern delivery.
Every clip can ship as H.264, WebM, HEVC, and a poster still — browser-ready in one pass.
Cut 9:16, 1:1, 4:5 — or any ratio you add — from the widest area that fits, then encode in the same formats.
Drop files or whole folders. Everything readable inside is queued and processed concurrently.
One 0–100 slider maps to each encoder’s CRF range. The video panel shows live H.264 CRF so you can dial in a known-good number.
Detects your FFmpeg build and greys out formats it can’t produce — no silent failures if a codec is missing.
// Installation
Install the app, then install FFmpeg once — Media Optimiser uses it to compress images and video. No account required.
Download
Click below to download the universal DMG — works on both Apple Silicon (M1–M4) and Intel Macs.
Open the DMG and drag to Applications
Double-click the .dmg to mount it, then drag Media Optimiser.app into your /Applications folder.
Install FFmpeg
FFmpeg is not bundled with the app. Install it with Homebrew (recommended), or point the app at an existing binary via Locate… in the sidebar.
brew install ffmpeg
Don’t have Homebrew? Install it from brew.sh, then run the command above.
Launch
Open Spotlight (⌘ Space), type media optimiser, press Return — or double-click from Finder. The sidebar shows FFmpeg ready when the encoder is found.
⚙ Dependency — FFmpeg
Media Optimiser is a UI around FFmpeg. Without it, the queue won’t encode. The app looks for FFmpeg in this order: a path you set with Locate…, a binary bundled inside the app (not included in this release), then common Homebrew paths (/opt/homebrew/bin, /usr/local/bin).
⚠ macOS Gatekeeper
If macOS shows "Media Optimiser cannot be opened because it is from an unidentified developer", run the command below in Terminal once after installation. This clears the quarantine flag macOS applies to apps downloaded outside the App Store — the app itself is not modified.
xattr -cr "/Applications/Media Optimiser.app"
After running this, launch the app normally from Spotlight or Finder.
